Predictions for water restrictions? Don’t throw in the towel yet

Gazing into a crystal ball for predictions on the future isn’t easy, especially when you’re talking about Mother Nature.  Vagaries in the weather have left Colorado high and dry for the past year and forecasts of no relief have spurred Denver Water into planning for spring watering restrictions. But for residents north of Denver, things aren’t quite as dire.  Not yet, anyway.

“It’s a case of we don’t know what we don’t know,” says Russ Sands, City of Boulder’s Water Conservation Program Manager, “it’s way too early to say if we’ll have restrictions.  If we have a few good storms we won’t have to; everything is so dependent on late winter early spring.” 

Coming off of a record hot season, Sands says decisions Boulder made in 2012 to ramp up treatment plants and storage kept the city in good shape to meet needs heading into 2013.  “But it’s a good reminder for people to be conscious of water use; we need people to pay attention to making sure irrigation is efficient.  Pay attention to the lawn and tackle irrigation issues.”

Northern Colorado Water Conservancy District isn’t ready to push the panic button either, says Brian Werner, Public Information Officer for the supplier of water to 33 cities and towns and 640,000 acres of farmland in northeast Colorado.  “We’re always cautioning people to wait until March and April, because those are our wettest months.”

Werner acknowledges concerns, especially after last year’s low rainfall and this winter’s piffle of snow.  After all, memories of the 2002 drought cast a shadow over the hearts of gardeners.  “2012 was the second worst runoff year for us; you don’t want to put another year like that on top of it.  But it’s followed three of the wettest years – 2009, 2010, and 2011. This is why we have water storage in this state.”

Yet storage is 25-percent below average in the District’s reservoirs, making the District cautious in its planning.  “We have some big months (of moisture) ahead of us; Mother Nature’s given us that before.  But with the way things are now, we’re casting a wary eye to the sky.”

As one of the older cities in the region, Longmont has managed its water portfolio to ride out weather downturns like the current dry spell.  Between their reservoirs and shares in the Colorado Big Thompson project, they currently have plenty of water to meet needs for 2013. 

“We track our water over a two year period and manage it conservatively, in case of dry year scenarios,” said Ken Huson, Water Resources Administrator with the city.  “We project having 144-percent of need for 2013 and 136-percent for 2014.  Our drought trigger is 135-percent or less so right now we’re not projecting going into mandatory water restrictions.”

Huson credits the long range vision of Longmont leaders in planning for water, plus aggressive water rights accrual programs and excellent storage capacity.  As the city grows so does it’s water portfolio.  “We get water rights through annexations; whenever a farmer wants land annexed for development, we require they dedicate all water rights to Longmont.  As it happens, the land around us has the senior-most water rights in the St. Vrain Basin, so we do a little bit better than other cities in getting the water we need.”

“Almost half the water used is outdoors for lawns and gardens.  We’re asking people to think about next summer now,” said Huson, “what do you need to do in spring to repair sprinklers?  And there are a lot of great seminars in spring on water conservation.”  Start by checking out the Center for Resource Conservation  for tips and classes, or check with local garden centers for their upcoming seminars.

Farewell to High Country Gardens

A friend leaned close to whisper awful words in my ear, words that make many gardeners in the west sad.  “High Country Gardens has closed down,” she said, speaking of the Santa Fe, New Mexico business that has been a class act in our region and leaders in developing and promoting water-responsible plants for over 19 years.

According to an article in The Santa Fe New Mexican, High Country Gardens and its parent company, Santa Fe Greenhouses, could not overcome setbacks caused by the effects of slow consumer spending, drought, fire, and competition from big-box stores.  Attempts to downsize failed to save the nursery.

“I think what David and Ava Salman did was to bring the message of the beauty of water wise garden plants to the country,” said Pat Hayward, Executive Director of Plant Select .  “People fell in love with them; all over the country people wanted that look.  David combined beauty and water wise gardening in ways no one else has done, creating excitement.”

Salman worked closely with the Plant Select, a program dedicated to finding, promoting, and distributing plants that thrive in our harsh, dry Rocky Mountain gardens.  “We’ve been working closely with David since I first came on as Executive Director.  Blonde Ambition blue grama grass (Bouteloua gracilis ‘Blonde Ambition’) was one of his introductions, and we plan to have more of his work.  The void is huge, but he’ll continue breeding plants and discovering new, beautiful introductions.  He has an amazing eye.” 

The current economy doesn’t seem to favor any business right now, but plant industry is dear to the hearts of gardeners.  When one of our own closes down we feel the loss, especially gardeners in far flung locations that have difficulty finding water thrifty plants in their communities.  Panayoti  Kelaidis, Senior Curator and Director of Outreach for the Denver Botanic Gardens, commented on his December 6 blog, Prairie Break , that High Country Gardens’ 19 years “is a hell of a run for any nursery.”

With many plant introductions of his own, Kelaidis said he was deeply saddened by the closing of the cutting edge business.  “No question, it was the highest caliber of production, the perfect combination of quality plants for the widest market.  Theirs was a magical gift to our industry.”

Kelaidis points to Plant Select for those looking to fill the void in searching for additions to water responsible gardens.  The plants Salman helped that program introduce will continue to thrill gardeners, keeping nurseries in Colorado doing well, by and large, said the esteemed Denver Botanic Gardens’ plantsman.  “Salman helped Plant Select create a pallet of plants ideal for western gardens, plants that are low water.  It’s like our own drought insurance for our industry.  These plants are adapted, tailored to our state and growing conditions.”

Rumors abound as to whether the catalog business of the company will find new ownership, but in the meantime, gardeners, take a moment to ponder where you purchase gifts this season and next year.  Check out local garden centers and nurseries for their stock, and talk to the staff.  Over repeat visits, you’ll find they become like family, and our patronage helps them stay afloat while we all ride out the economy.

A few final chores

More fall leaves… (Photo credit: life is good (pete))

Though the season seemed endless, the recent cold snap has convinced even the die-hard gardeners that fall is well under way.  Winter is around the corner, so before the holidays distract you and chill days drive you indoors, take advantage of the lingering warmth to tuck the landscape in to bed.

 Here are a few suggestions for helping your garden head into winter:

 Wrap young trees.  With a few moments out of your busy schedule, wrapping a young tree to tuck it in for winter is an easy way to keep your sapling strong.

 Winter can be a rollercoaster of warm days and cold nights, which wreak havoc on young, thin barked trees that have not grown old enough to form protective corky bark. Sun hitting trunks on south and west sides warms the bark and cells underneath, causing them to lose their cold protection.  As nighttime temperatures plunge, these cells freeze and burst, resulting in sunscald on the trunk, an area that will be prone to disease in summer.

 Sapling fruit trees are vulnerable to sunscald, as well as lindens, honeylocusts, ashes, oaks, maples, and willows.  Protect them for the first two to three years they’re in your landscape by wrapping them with tree wrap in early in November.

 Wrap from the ground upward, overlapping each layer over the lower one by one-half-inch until you reach the lowest branch.  Use tape to hold the wrap in place, making sure the tape doesn’t stick to the trunk.

 Mulch perennial beds.  Leaves make an excellent blanket for protecting perennials and woody plants from the ravages of winter.  In Colorado, thawing and freezing can lift roots, but covering the soil with a four to six-inch layer of leaves will keep temperatures consistently cool.

 If the leaves are from trees that aren’t diseased, pile them up around your plants and let the ones that blow into the beds settle there for winter.  In spring, rake the leaves out and put them in your compost pile.

 Compost rotting, dead plants to convert them to organic material that, tilled into the soil, holds water and nutrients for roots to take up.  This is a great soil amendment to have on hand in spring.

 To build a compost pile:

-          Select an out-of-the-way area at least 4-by 4-feet wide.

-          Gather together both green and brown plant material – you’ll need twice as much brown material as green.

-          For faster composting, chop the plants into small chunks before mixing them into the pile.

-          Layer brown and green material into a pile, adding water with each layer until the pile feels damp, like a sponge.  If the pile is soggy to soaking, add more material in until it dries a little.

-          The compost should heat up within a week and be very warm to the touch.  Once it begins to cool, turn it from the outside in and sprinkle with more water to recharge the microorganisms.

-          When the compost no longer heats up after turning, looks like crumbled humus and has an earthy smell, it’s ready to be added to your soil.

 Give trees and shrubs one last, big drink.  Research has shown that the best thing to do for trees and shrubs as they head into winter is to give them a deep soaking before the ground freezes.  This helps prevent winter desiccation of branches, needles, or evergreen leaves, so for good woody plant health, give them a last soaking when temperatures are warm.  Be sure to disconnect the hose from the faucet once you’ve finished watering.

Mighty ‘Mato good for Colorado

  Describe something as stronger, faster, and able to fend off foes, and most people think of caped crusaders in brightly colored tights.  Toss in a “and their tomatoes are amazing!” and you’re written off as talking to adolescent boys and Boris Vallejo fans.  But one look at the performance of this year’s hot new product, and you’ll be tempted to try a few in your garden to get a taste of what it’s like to live with a superhero.

 If you decide to plant a Mighty ‘Mato, buckle your seatbelts; it promised to be one wild summer ride.  The latest improvements to vegetables comes to us from the Pacific Northwest, where Log House Plants have perfected the art of fusing tomatoes to a rootstock that amps up America’s garden sweetheart with super natural powers. 

 “This is not a genetically modified organism; it’s a grafted plant,” says Brian Wheat, co-owner of Lafayette Florist, 600 South Public Rd. in Lafayette, CO, “it’s a modern tomato on an old world, wild tomato rootstock.  This is the same theory as roses, where they put roses on roots to have bigger flowers, bloom longer.  We want tomatoes to survive here, with our cool nights, poor soil, and temperature swings.  When people see how many tomatoes they get, how huge they are, they’ll be overwhelmed to see it performing so well.”

 To be honest, anything that touts itself as the must-have of the season gets a stink eye from me until it’s proven itself, because there are a lot of people who devote their lives to separating gardeners from our money.  Fads come and go, usually with late night television ads that, if you act now, will send you a few Ginsu knives they have lying around.  Wheat’s seen them all.  “Sometimes there’s a hula-hoop idea that is beautiful in its simplicity, like the Topsy-Turvy planter.  They’re perfect for certain places, like patios or those who don’t have gardens any more but want a little tomato plant.  I want my customers to get the most out of their garden; it’s the most important thing to me.”

 Getting the most from places in Colorado isn’t always easy, with changing elevation and a short growing season.  But this beauty and the beast pairing holds a lot of promise for gardens in challenging locales, like gardening at elevation, where Wheat sees the earlier cropping and tolerance to temperature swings of the Mighty ‘Mato beating out traditional tomatoes.  “When you look at its benefits, this tomato says Colorado, not Illinois, where I’m from.  They have rich soil, rain.  This makes sense for us; it starts producing earlier and gives fruit later into the season.”

If you’re growing it in a container, think big; the root system on Mighty ‘Mato requires a whiskey barrel or larger size pot.  And caring for a grafted tomato differs from a standard one:  you don’t plant them deeply.  Along the lower part of its vine, tomatoes have lumps, called root initials, that often develop into roots.  When this happens to a grafted tomato, the genetics of the top growth can take over, reducing or cancelling out the robust characteristics the rootstock provides.  Plant them at the same level as they are in the pot, making sure that the graft line – you can clearly see it – is above the soil. 

Many varieties of heirloom and hybrids are available on the Mighty ‘Mato, including:  beefsteak, Mortgage Lifter, Black Krim, Green Zebra, or Cherokee Purple slicers.  Cherry tomato fans will love the better-than-bumper-crop production of Sweet Million, Black Cherry, or Yellow Pear.  I’m trying Brandywine, because I’ve noticed a decline in its vigor in my garden and want to see if grafting gives it the jolt needed to grace our table with the tangy, old fashioned flavor love apples are known for.

Gardening to the Stones

The Rolling Stones' "Tongue and Lip Design" logo designed by John Pasche in 1971 (Photo credit: Wikipedia)

Before we leave April, let us be thankful for many things:  warm days, cheerful flowers, and the 50^th anniversary of the Rolling Stones rock band.   With that many years of music, there’s always something to pop up on the iPod that applies to gardening.  And while we don’t all have Moves Like Jagger, we can get our gardens going with a few selections to celebrate the greatest band in Rock and Roll history.

 Under My Thumb is the perfect opening song for gardeners tidying the beds in spring cleanup.  After all, it’s under our green thumbs that plants thrive.  Thanks to the hot weather, soil temperatures have warmed, and it’s time to pop potatoes, onions, rhubarb, and asparagus in the ground.

 Poke around the perennials beds and pull back mulch slowly from those that have nosed up out of the ground.  But be cautious and don’t leave them too exposed – we still have at least a month left of unsettled weather and plunging temperatures can cause tender plants to beg you to Gimme Shelter.  If you cave into the temptation to plant tender vegetables, have buckets, cloches, or other coverings handy in case of frost.

Getting out the power equipment and readying it for the season is the perfect time for Start Me Up.  Mowers, chainsaws, trimmers – anything gas powered should have a once over to check oil, sharpness of blades, and that bolts are tightened.  Hand tools should be sharpened and lightly oiled, with grip tape or rubber in good shape for handling.  With a few minutes of preparation, the tools will never stop, never stop, never stop for you throughout the season.

Weeds have sprouted early this year, giving us a Goats Head Soup of problems like puncture vine (Tribulus terrestris), commonly called goat’s head, that causes painful problems for hands and feet.  The plant starts off cute, with many small leaflets forming a mat across the ground, but heaven help you when it becomes mature, because this plant’s small burrs hurt when they grab you.  Armed with a chemical that stays in the skin after the bur has been pulled off, the painful sting lasts for quite a while. 

The Rolling Stones understand the mind of a gardener; we routinely hum You Can’t Always Get What You Want when going about lawn care, or perhaps it’s (I Can’t Get No) Satisfaction.  Either is an anthem to the mindset needed to grow turf in Colorado, because lush swaths of green always succumb to blistering heat.  Without realistic expectations, well, You’d Be A Fool To Cry.  Perfect, weed free, dense lawns are a worthy goal, but keep it real and enjoy a lawn with a few blemishes.

Let it bleed.  A gardener’s yard is filled with opportunities for mosquitoes to lay their eggs, since we have pots, buckets, saucers, bird baths, ponds, wheelbarrows, and other accessories stacked around the yard.  If you look at the list many of the health agencies have on common breeding areas, gardeners’ yards appear to be mother ships for these insects. 

But there is something you can do to reduce the problem of mosquitoes:  change bird bath water twice per week; dump out water that collects in the dish beneath pots; turn over unused pots, saucers, trays and buckets; and use Bt doughnuts to float in your ponds or water features.  Bt, short for Bacillus thuringiensis, is a natural way to kill off the mosquito larvae in your water.

With a little attention to spring start up in the garden, you’ll be assured of having plenty of Dead Flowers to send to people, or place on your tables in festive displays.  For the song isn’t about dried, blackened, crispy blooms; instead it’s all about floral arrangements being sent for various events.  Get out your pruners and clip a few blooms for your home, and dance around to the timeless music of the Rolling Stones.

Sunscreen a must for gardeners

It nurtures the seeds warms the soil; with it the plants we love blossom.  But the sun that’s warm on our face is also wreaking havoc on our skin, and gardeners need to be savvy about sun protection.

“Sun does a lot of good; it’s good for mental health and makes you feel great.  And 10 to 15 minutes twice per week is what you need for vitamin D,” says Mary Buller, Chair of the Skin Cancer Task force of the Colorado Cancer Coalition.  “But more people are getting Melanoma in Colorado than in the rest of the United States.  It’s a combination of three things:  our altitude, 300 sunny days per year, and outdoor lifestyle.”

That outdoor lifestyle is what puts gardeners at risk, puttering away in our yards under the broiling sun.   That we spend more time out there once we’re older increases the chances for skin cancer, since cumulative exposure over a lifetime is part of the risk factor.

“Scientists had been thinking that the most dangerous sun exposure you get is as a child; but a new study shows older humans can get just as much risk, or you make it worse,” she said, by heading outdoors once retirement arrives.  Since gardening is a popular pastime, keep yourself safe with a few tips:

 - Schedule your gardening around peak UV hours of 10 a.m. to 4 p.m.  Climbing temperatures work in our favor by driving us indoors during the heat of the day.  Cool mornings and evenings are the best time to garden and stay sun safe. 

 - Be smart when using sunscreen.  SPF rating will tell you two things:  how strong the sunscreen is and how long it will last.  Lotion with SPF 15 blocks 93-percent of UVB, SPF 30 96-percent; beyond that there is a diminishing return on benefit versus cost, says Buller.  “It’s impossible to block a hundred percent UVB, so the higher numbers – that often cost more – might not be a good purchase.”

Better to purchase slightly lower numbers and reapply more often, but to ensure protection, know how long your sunscreen lasts.  Though that is unique to each person, Buller gives a simple equation for planning reapplication.  “Take the number of minutes it takes for your skin to redden and multiply it by the SPF.  The total is the length of time, in minutes, that sunscreen will work.”  For example, if you redden in 12 minutes and use SPF 30, you should reapply it every six hours. 

Not reapplying sunscreen often enough is one reason many end up sunburned, says Buller, but how you apply it is also a factor.  A full ounce should be slathered on each time you apply it, using the two-finger method found on their website,  sunsafecolorado.org/.  Keep in mind that sweating reduces the length of time between applications, sometimes as often as every 40 minutes.

 A combination of cover up and sunscreen is the best option for gardeners, so toss on a wide brimmed hat, slacks, and shirt with long sleeves before heading out.  Inexpensive, lightweight, sun protective clothes made from wicking fabric take the heat out of covering up, and you won’t have to start spending more on your wardrobe for weeding than you do for your tools.

 But if your budget prevents you from purchasing new clothes, grab a long sleeve shirt from your closet; as long as the fabric is tightly woven it helps.  “Hold it up to the light, and if you can’t see light coming through it, that’s best.”  Darker colors absorb UV, while white is better at reflecting it.

Loveland Garden Tour a don’t-miss event

 Gorgeous gardens, amazing artwork, and cheerful plants await you on the 8^th annual Loveland Garden Tour, tomorrow, June 25.  Benefitting the Loveland Youth Gardeners, if you’re one of the lucky ticket holders, here’s a sneak peek at the treats in store for you: 

The tour has returned to downtownLoveland, winding through the cozy west side neighborhood to visit seven amazing gardens.  At each stop on the one-mile walking tour you’ll find gardens hand crafted by the gardeners who live there, personalizing their yards with raised beds, trellises, and an assortment of found items sure to make you reconsider tossing anything away. 

Following the map during the pre-tour event, I was amazed at the sense of community this tour has; you’ll find yourself waving hello to neighbors as you walk past, or stopping for a quick chat over a garden fence at a nearby home.  

Arriving at tour stops, you’ll goggle over front yards filled with perennials, roses, or shrubs, but don’t be fooled into thinking that this is all there is to see.  No, the inspired organizers take you behind the fences and into backyards that are a sheer delight, their hidden beauty a breathtaking example of the artistry of gardeners.  From formal beds and Asian-influenced screens to chickens and Rocky Mountain Natives, the gardens are true gems to be savored.   The copper-topped beehive in garden 3 caught my eye, as it’s easily the most beautiful bee box I’ve seen.

Plan to spend a lot of time in garden four, says Vonne Zdenek, one of the Colorado Master Gardener volunteers, because a little bit of time won’t work in the quirky yard packed with recycled items.  Old shoes, can, tools, and appliance parts are turned into garden art that brings grins to every face.  “It’s just amazing – he sees nothing odd about any of this,” says Kathi Taylor, “though it doesn’t match, it works together.  He’s brilliant!”

Local artists also get in on the act, with displays of metal sculpture, furniture, birdhouses, stepping stones, and truly lovely potting benches.  Art is for sale so if you find a piece you like, snap it up before it’s gone home with another gardener.

Tickets are $15 (children 10 and under free) and are available at Earle’s Loveland Floral & Gifts, Gateway Garden & Home Center, Loveland Garden Center, Rabbit Shadow Greenhouse, Rowe’s Flowers & Gifts in Loveland. InFort Collins, find tickets at Bath Garden Center & Nursery, Fossil Creek Nursery, Fort Collins Nursery, Wild birds Unlimited, and Gulley Greenhouse.

Edible Schoolyard New Orleans

It didn’t look like much of a school, with the barbed wire fencing and modular classrooms crowding the yard.  But FirstLine Charter Schools founders saw in it the potential to take a failing program and turn children’s lives around.  But ten days after opening their doors in 2005, Hurricane Katrina struck, bringing five feet of flood waters to smother the school grounds. 

 Out of destruction an ambitious recovery formed, and with the help of dedicated volunteers and a bit of star power, the humble grounds of Samuel J. Green school transformed into Edible Schoolyard New Orleans.  Sowing, growing, harvesting and cooking are part of the curriculum served up at this innovative k-8 school.

 “The garden is such a visible sign of positive change,” said Kelly Regan, Community Partnerships, Volunteer, and Family Coordinator.  “We made that promise, for the kids’ grades to come up and for them to be happy.  We wanted the school to be the heartbeat of the community.”

 In the aftermath of Katrina, many sought ways to help, including Chef Alice Waters of Berkeley, California, founder of Chez Panisse Foundation the organization devoted to promoting Edible Schoolyards.  Networking with local food legends such as Emeril Lagasse and New Orleans Saints Quarterback Drew Brees, Waters pulled in funding and support for the project and in 2006, the garden opened. 

 Where modular classrooms stood, the one-third acre garden grows, flush with late season harvest of eggplant, tomatoes, peppers and garlic.  Yearly, 3,000 pounds of produce is harvested, going into the huge teaching kitchen for children to learn the finer points of food preparation, table manners, and teamwork.  Large windows of the kitchen overlook the garden to reinforce where the bounty comes from.

“When we started there wasn’t one piece of fresh fruit or vegetable given to the kids by the contracted food supplier.  Here, 98-percent of the kids are from families at or below poverty income, but they were dumping their food in the garbage can even though they were hungry,” said Alison Heston, School Food Outreach Coordinator.  Now they get three servings of fruit per day, plus whole grains and all the food is made from scratch. 

Says Regan, “It’s not just about changing the food by putting something new in front of them. We have them involved with growing so they’re interested in eating their food.” 

In total, the 490 students receive 24 lessons over the course of the school year, where chef April Neujean leads the class by holding up the ingredients, talking of them, then letting the kids touch and smell the food before working on the day’s dish.  Teams work together to chop and cook the meal.

To solidify community ties, every other month the school hosts an open garden day, where the neighborhood is invited to stop by for tips on gardening or harvest.  In off months, youth leadership program participants learn small business skills by selling the produce at the Farmer’s Market.

 Sustaining the garden takes investment by community leaders in order to fund two full time staff and support the 20 to 25 volunteers that help in the garden each week.  With competition for dollars fierce, the school thought creatively and garnered support from a pantheon of food stars such as the Emeril Lagasse Foundation, Ruth U. Fertel Foundation (of Ruth’s Chris Steakhouse), Slow Food New Orleans, Crescent City Farmer’s Market, and the Culinary Corps.

Their vision paid off: student performance has improved greatly, moving the school from one of the city’s worst performing to one-star status.

Weeds are distracting me

Author’s note:  here’s a classic article from 2006, published in the Boulder Daily Camera and Longmont Times-Call.

   Perhaps I have stepped over the line when it comes to gardening.  It happened recently when I slipped out the door in my old, pink bathrobe to get the newspaper.  I spotted a weed growing in the garden and became immediately sidetracked, swooping to pluck it from the ground.  Over an hour later I returned to my senses, knees and robe hem dirty, weed parts dangling from my fingers, wondering what on earth possessed me to spend an hour gardening in the front yard in my pajamas.

    Weeds have a lot to do with this erratic behavior.  They’re sprouting at an alarming rate.  While I am impressed with the growth of most plants at this time, the weeds are truly coming up faster than I can keep up.  Pulling weeds is a season long job and in pursuit of weed control many gardeners abandon some rudimentary connections to the world around them.  One colleague of mine told the tale of her small children coming to her while she was weed pulling to ask what was for dinner.  Distracted by weeds, she responded “I don’t know – what are you fixing?” 

   Some of the tougher weed characters in the garden may change from year to year.  This year there is Western Salsify (Tragopogon dubius), a grassy-looking biennial that is sprouting in many gardens.  Western Salsify’s grass-like leaves arise from a central stalk which, when damaged, oozes a milky sap.  Because it has a long taproot, plucking from the soil when it is very young will give the best control.

    Redroot pigweed (Amaranthus retroflexus) can grow to monstrous size – often two to three feet tall with flowers that bristle with spines.  The seeds of this annual weed are tiny and rapidly spread.  Redroot pig weed can be recognized by it’s characteristic reddish stalk and taproot.  Pulling it when it is young will give good control.

    Perhaps the best-known and most hated weed in our gardens is field bindweed (Convovulus arvensis).  Despite being a member of the morning glory family, there is nothing ‘glorious’ about it.  It snakes through the garden.  It entwines itself through branches, along trellises, and into every nook and cranny of the area.  Pulling this plant results in a nightmare out of Greek myth – four hydra-like plants sprouting from the single plant pulled.  Stamina is required in pulling to control this plant because it must be done repeatedly and frequently, until the energy in the root system is exhausted and the plant can no longer regenerate.  Battles with bindweed are epic, and are, in my mind anyway, the true summer Olympics.

    Gardeners should beware of the sinister puncturevine (Tribulus terrestris), also called ‘goat’s head’ due to the shape of the burs.  This plant starts off cute, with many small leaflets forming a mat across the ground.  It looks nice, but heaven help you when it becomes mature, because this plant’s small burs hurt when they grab you.  The burs have a chemical on them that stays in the skin after the bur has been pulled off, leaving a really painful sting that lasts for quite a while.  Any plant that is known to flatten bike tires and seriously injury livestock should be removed.

    If pulling weeds to the point of obsession is not for you, mulching garden beds is a great method of weed control.  In order to control weeds mulch should be applied to a depth of four inches across the surface of the garden.  Weed control fabric, when laid underneath the mulch may help, but research is suggesting that this fabric may limit water and air from getting to roots.

Plant sales kick off the season for shopping

Throughout the long, dry winter, gardeners dreamed of spring, when we could get outside and get growing.  And while catalog shopping is nice, what we really wanted was to get our hands on some plants and sink them into the soil where they could thrive.  Green thumbs are nurturers by nature, coaxing seeds and seedlings into glorious displays in summer.

So it’s no surprise that when a group of gardeners gets together, they throw a plant sale to benefit causes close to their hearts.  This weekend kicks off the season of plant sales, where you can pick up plants while supporting community causes.  Make room in your schedule and planting plans to attend several of these worthy fundraisers.
