WATER YOUR TREES (and Shrubs and Perennials)

 We can’t stress enough the need to water trees and shrubs when we’ve had so little snow this winter. The following information is from CPR News (cpr.org).Focus on the most vulnerable treesJim Klett, a horticulturist at Colorado State University, said not all trees face the same threat from drought and dry weather. Any trees planted within the last three years should be first in line for the hose, according to Klett. Evergreen trees should be watered next since their needles continue to demand water over the winter.”With all the foliage on them, they’re going to desiccate and dry out very quickly. So evergreens are even more critical than deciduous trees,” he said.Finally, he recommends watering any trees with shallow root systems like birches, maples, lindens, alders, hornbeams, dogwoods, willows and mountain ashes.Wait until the weather warms upKlett advises only watering trees when temperatures rise above 40 degrees Fahrenheit. Mid-day watering will allow the moisture to soak into the roots before freezing temperatures at night.Provide the right amount of waterPay attention to the thickness of the trunk. When trying to figure out how much to water, Klett said to apply 10 gallons of water for every inch of trunk diameter. For example, a 3-inch tree would get about 30 gallons about every three weeks.It’s a mistake to pour all the water directly against the base of the trunk, Klett said. Instead, he recommends watering along the “drip line,” which is the area beneath a tree’s farthest-reaching branches.”You probably want to water there, because that’s where most of the feeder roots are for the tree,” he said.Mulch it goodKlett recommends applying mulch around trees to conserve soil moisture. If the ground gets dry enough to crack, the extra layer can also help protect tree roots from cold, dry air.
  Watering Shrubs and Perennials Much of this information comes from the Colorado Extension Service Fact Sheet:   http://extension.colostate.edu/topic-areas/yard-garden/fall-and-winter-watering-7-211/Water when the temperature is 40 degrees or above. Water in mid-day so that water has a chance to soak into the ground before the temperature drops below freezing.

Shrubs, including roses, and fruiting varieties, need five gallons for a small shrub (less than three feet), and 18 gallons for a large shrub (more than six feet) on a monthly basis from October through March. If they are newly planted, increase to  twice monthly using these same amounts at each watering.

Perennials that have been planted in the fall have less time to establish than those planted in spring, so they could use a bit of water during warm dry winters.  Also water bulb plantings to be sure they do not dry out as they are trying to form roots.

Tis the season for giving!

Annual Meeting Speaker:
Valerie Belding, owner of Sunset Greenhouse

“Bedding Plant Selection for Sunset Greenhouse”

We are fortunate to have Valerie Belding as our speaker this year. Valerie Belding sprouted in the greenhouse industry in 1976 when her dad, Don Phelan, bought Sunset Greenhouse. In 1981 her father founded Phelan Gardens where she worked part-time as a teenager and eventually developed her career learning about all the aspects of the business from plants to garden center to cash register protocol. She has been in the horticultural field 37 years.

Seven years ago, she bought Sunset Greenhouse from her siblings Mark Phelan and Monica Phelan, and maintains the bedding plant business with the same standards and protocols as in 1976.

She currently lives outside Woodland Park with her husband and kids and has found a balance of enjoying life, raising kids and running a business! Hiking the trails of Colorado, she’s developed a deep appreciation for native plants, their adaptability to extreme conditions and survival in various climates, especially in Colorado. Valerie offers a unique insight into the horticultural field, and she will share how she develops her product line as it’s persuaded by plant breeders, influenced by marketers, and inspired by customers, not to mention what fits her own growing criteria!

We are truly grateful for your donations whether it’s your time, materials or funds.

HAS Board’s Favorite Performing Plants of 2020

by Erin Eisen
HAS Trustee


As it is February—still winter—and it is too early to do anything out in our gardens, we thought it would be fun to canvas some of our HAS Board members and ask what plant they thought stood out this past year. Some of their favorites just might become yours this next year!

Chella DiMenza: This beauty is Eriophyllum lanatum ‘Takilma Gold’ or Oregon Sunshine. It has a wonderful bloom of bright yellow bi-colored flowers over a mound of evergreen woolly gray foliage. It blooms from spring to fall. A native wildflower, it is growing in a Zone 4 environment at 8500 ft. It likes full sun, with low/medium water. Deer leave it alone! The pollinators love the bright flowers. I have been able to divide the root ball of the original plant and move to other areas with great success.

Nancy Taylor:  When arriving in Colorado six years ago, knowing nothing (NOTHING) about gardening here, I learned that Lady’s Mantle can be a good friend, not a nuisance. A local landscaper had planted some in one of our semi-shady flower beds where over time they mushroomed into a gigantic width, encouraging division and donation. 

Interestingly shaped leaves and chartreuse flower bracts are redeeming qualities. The flowers can also be dried for arrangements. Lady’s Mantle Alchemilla A. mollis) grows 12-14″ tall.

Terry Webb: I always thought this was Salvia ‘Heatwave’, a real hummingbird magnet. It survived the light freeze/snow in early September and just bit the dust with this past week’s hard freeze (late October). It has seen several years in my yard, which has poor soil and is windy and dry. I watered it only a couple of times this year although it is planted at the base of a large rock (which retains moisture). I leave it up over the winter, cutting it back in spring when I see a little green coming up. The problem is, it might be an Agastache (my investigation yielded confusion)! It grows to be about 36”x40“ high, and is deer- and rabbit-resistant.

Terry Webb: This groundcover, Teucrium cossonii, can be purchased from Perennial Favorites and High Country Gardens. Sometimes it is sold as T. aroanium. I learned from Panayoti Kelaidis, in a blog called ‘A Tangled Tale of Two Teucriums’, that cossonii is the only correct name. This is also deer- and rabbit-resistant, and seems to appreciate dry conditions. It is 2-3” high, and 28” wide at two years. Pollinators love it. I love it too.

Allexia Arcuri: My favorite plant this year was my Opuntia Cactus “Peach Pie”, which I bought from Kelly Grummons. It is a cold hardy cactus and did not disappoint. I had five flower blooms, which were like beautiful little apricot jewels shimmering in the sunlight. During winter, the cactus pads develop a purple wash. This plant is truly a diamond in the rough!

Diane Engles: The plant that has performed splendidly for me this year is Windwalker™ Royal Red Salvia (darcyi x microphylla Windwalker™) from Plant Select. I bought four plants in 2.5 inch pots this spring and they grew in quickly reaching 3′ tall by 2′ wide, blooming repeatedly throughout the summer into September. This salvia is hardy to Zone 5. I was concerned that the color might be hard to combine but it is a crimson, dusky red that looks good with many colors, including pink.  It was fun to watch hummers feeding on the blooms–it truly is a hummingbird magnet! I’m looking forward to an even better show next year.

Susan Flynn: I love my Moonlight Broom (Cytisus scoparius ‘Moonlight‘ ). It is just lovely every single year, no matter what, and it is so fragrant as well. This is a picture I took this past spring. It grows up to 5’x5’ and is hardy to Zone 5b.

Erin Eisen: My favorite plant, unexpectedly, was an annual that outperformed itself in my front porch containers. This picture is a result of the growth of small 2-3” pots of Begonia Waterfalls Encanto Pink (Beekenkamp Plants), combined with Proven Winners’ Graceful Grasses Toffee Twist. 
I have some serious deer issues, but they stayed off the front porch and didn’t touch my planters (at least until the fall when they started getting hungry). I may have to try for a repeat performance this year!
