Monday’s storm dropped an average of 4 inches of heavy damp snow
across Littleton, Highlands Ranch and Lone Tree, according to
observers for the Community Collaborative Rain and Hail Network, or
CoCoRahs.
That storm, and the preceding storms of March and April also
lowered the boom on flowering plants and trees.
For Littleton residents, don’t expect the crab apples across the
city to be a riotous display. The storm of April 10 nipped their
buds.
Landscape fruit trees are at risk when the winters are warm and
the springs snowy, as the warmth encourages buds and blooms. Then
freezing temperatures kill that years’ buds.
“It was a perfect storm of weather circumstances that killed our
tree blossoms,” said Alissa Shanley, owner of B.Gardening Landscape
Design. “The warm temperatures of January and February tricked our
flowering trees into blooming early. We were then hit with three
freezes in a row which effectively killed most of the tree blossoms
and no blossoms mean no fruit.”
Flowering trees were not the only plants affected by the spring
freeze. Early flowering shrubs including forsythia, lilac and rose
bushes also incurred damage. According to Shanley, people who
trimmed their rose bushes before the freeze may find them dead or
sustaining much more die-back than usual.
Despite the bounty of moisture the March and April storms
brought to the Front Range, the near-drought conditions through the
winter also took a toll an yard plants.
“This winter coming into spring has been particularly hard on
our plants,” said Carole Kastler, owner of Camelot Design. “It is
essential to hand-water your trees and perennials during the winter
to keep them healthy and in some cases, alive.”
Kastler said she has seen many dead boxwood shrubs throughout
the metro Denver area as a result of the dry winter.
Associated Landscape Contractors of Colorado, a trade group for
landscape designers, installers and maintainers, has some tips to
replace the blooms this year.
If flowering trees and shrubs were damaged by the spring freeze,
think about adding some extra splashes of color to the landscape by
adding a few more annual flowers.
Look for later-blooming perennials that will add a little color
this year and, more color in subsequent years as the plants become
more mature.
To ensure that you have color and blooms throughout the year,
landscape professionals recommend incorporating a mixture of
early-, mid- and late-blooming trees and plants throughout your
landscape.
