Garden Advice: Don’t Prune that Crown!

Quercus_Oak_COS-CO_LAH_1854It’s a common question. You’ve just planted a new tree. In the process, the plant has lost a significant portion of its roots—sometimes up to 95 per cent! Should you prune back the crown to compensate?

The intuitive answer would be yes. We assume that with fewer roots, there’s no way the plant will be able to sustain all that foliage on top—and that’s the advice I see on website after website. But if you do decide to prune, you’ll be doing the tree a disservice. You might even kill it! How can this be?

Impressive Pineleaf Penstemon

 

Penstemon pinifolius - Pineleaf Penstemon @SantaFeGreenhouses 20089jun28 LAH 067Looking for a small perennial with a big impact? Consider Pineleaf Penstemon (Penstemon pinifolius). True to its common name, this low-growing plant has long, narrow leaves similar to pine needles. They hang on well into winter, and may be evergreen even in some colder climates. But it’s the flowers that steal the show. The dense mass of vivid scarlet red simply takes your breath away!

Cool Birds

1991-08 Karin & Teri in sprinklersAs my grandmother always said, “Horses sweat. Men perspire. Women glow.” How do we avoid this sticky situation? Kids run through sprinklers and adults head for the air conditioning, but what do the birds do when the thermometer climbs? They don’t sweat they can’t take advantage of the A/C. However, that doesn’t mean they just sit there and bake, either.

Because birds have relatively high body temperatures—a Golden Kinglet’s temperature was measured at 111° F!—it’s critical that they avoid getting too warm. Many essential proteins begin to break down at temperatures just a few degrees higher, so overheating could easily be fatal. Thankfully, birds have all sorts of ways of beating the heat.

Garden Advice: Kelp Belongs in the Ocean

The products sold to improve the health of our landscapes seem endless; I just wish more of them actually worked. I recently received an advertising postcard in the mail. At first glance, it appears that they are selling a valuable product. After all, who doesn’t want to “improve the health and vigor” of their trees and shrubs? But then I reread the claims and some red flags went up.

Garden Hopping

Gazebo_HASDemoGarden-COS-CO_LAH_9487As an enthusiastic gardener, I spend a lot of time in my yard, but it’s always a treat to visit other gardens. Just as sandwiches always taste better if I don’t have to make them, a garden I haven’t tended seems more lovely somehow. Perhaps it’s because I’m not responsible for pulling every weed; I can just relax and enjoy the flowers.

I’ve been garden hopping a lot this month. Earlier this month, our house suffered 45 minutes of half-inch hail accompanied by a torrential downpour. Runoff scoured my gravel paths and adjacent flower beds—I  never did find some seedlings I had just planted. Happily, other parts of town completely missed the destruction. I find their intact flowers and un-shredded leaves therapeutic, easing my bruised sensibilities while my garden heals. (more…)

Natural Landscaping

2015-04-13 13.18.35-1

Two years ago, our new home was a blank slate. Nothing grew on our lot, not even weeds. We’re located on a hillside, and the summer rains were eroding the subsoil left by the builder. It could have been discouraging, but I couldn’t wait to get started.

Landscaping is so much fun! It’s a chance to be creative and to express one’s personality. While I had some help with the overall design (the builder provided a voucher for a professional designer), the result is exactly what we had in mind. Our little piece of Colorado Springs reflects my love of birds and other aspects of nature, plus my husband’s desire for a place to relax.
