Question of the Week


Siberianelm2

A few weeks ago, some of the earliest green could be seen appearing on trees in our neighborhood. It’s always exciting to see those first tree leaves coming along isn’t it?

Well….the fairly invasive Siberian elm (Ulmus pumila) – pretty much the best example of a “trash tree” in our area –  likes to play a little trick on us. The tiny bits of green we see covering them are actually their ripening seeds. (more…)

Ornamental grasses flattened by heavy snow

You know those fabulous ornamental grasses we all plant for great winter interest? Well, this is just a friendly reminder that it’s time to cut them down so they can get going with this season’s growth. They’ll grow anyway if you don’t cut them down, but they sure won’t look too nice (surely you’ve seen those poor parking lot ‘Karl Foerster’ feather reed grasses that never get any attention after planting – getting shaggier and more dismal each year with green shoots pressing up through many years of dead leaves? Maybe if we all travelled with loppers in our cars, and we each agreed to cut down just one, we could make a difference!).

White-lined Sphinx Moth_DBG-CO_LAH_6147Q: What are those huge moths siphoning nectar from the evening primroses, fluttering around the catmint, hovering in front of the Red Feathers (below), and flocking (what do you call groups of moths, anyway?) around the lilac blooms?

A: They remind one of hummingbirds as they sip nectar through their long proboscises, so it’s easy to see howthey got one common name—Hummingbird Moth. However, these aren’t birds, but insects—sphinx moths in the family Sphingidae.

A week and a half ago (Apr 13 and 14), we had two nights of hard freezing temperatures in much of the Pikes Peak area. Temperatures got down into the teens, and it seemed likely that many early blooming fruit trees might lose their almost-ready-to-open blooms. (We’ve written about fruit trees and freezing temps before here.) Amazingly, given what we know about fruit tree blossoms and killing temperatures, it seems that many of those trees escaped losing all of the blooms and may have only suffered some frost/freeze damage.

Here are some photos of a crabapple that is blooming in my yard this week (about a week later than “normal” – it was just about to open before it was set back by the freeze). (more…)

Irrigation is a super important part of vegetable gardening, and in our arid area, we tend to pay even closer attention to it. A vegetable garden left to be watered by Mother Nature here is not much of an option (though efforts can be made to maximize the benefit of any rainfall). But the vegetable gardener is going to have to supply extra water, so let’s look at a few different irrigation possibilities for vegetable beds:
1) Handheld Hose-End Sprayer
2) Overhead Sprinkler
3) Soaker Hoses
4) Drip Irrigation (more…)

Xeriscape Demonstration Garden in winter

Every winter is different (thank goodness!), and this year, we’ve had a pretty good solid winter with somewhat consistently cold temperatures and periods of decent snow cover. Some of those cold snaps have kept many of us indoors, getting a little stir crazy. We gardeners gaze out our windows, looking for that “winter interest” we hear so much about. If we happen to be houseplant people, we can put our gardening attention there. If not, maybe we peruse the seed catalogs again and again…

It seems mid-February is when I notice many of my fellow gardeners starting to get a bit tired of being indoors and itchy to be doing something, anything, to jump start their green thumbs for the upcoming season. If you’re one of this group, may we suggest the following five things you can do to ride out the end of winter into early spring: (more…)

Ponytail Palm_LAH_9915Q: What houseplant can I grow that isn’t fussy about food, water, light, or much of anything else, is ignored by pests, and looks good year round?

A: Amazingly enough, the perfect (or nearly perfect) houseplant does exist. Meet the Ponytail Palm: not fussy, not buggy, and eternally good looking. Granted, I have yet to see flowers, but with all its good points, who cares about flowers?

While “Ponytail Palm” is the most widely used common name, you might also see these plants labeled as Elephant’s Foot, Monja, or Bottle Palm. This is a case where the botanical name (Beaucarnea recurvata) comes in very handy. At least that way we know which plant we’re talking about!
