Committing Tree-icide: Staking & Protecting

20200522_101626

If we lay perfectly still for weeks and months, we know that our joints will stiffen and become less flexible. Movement will become difficult. Bending will hurt. Holding perfect still is bad for our health. And it’s bad for trees as well. Yet, every year hundreds of trees are splinted into immobility by well-intentioned gardeners. It’s no better for them than it is for us.

We have a tendency to regard a newly planted sapling as fragile, and we want to protect it as best we can. That trunk looks so flimsy, as if the first breeze will snap it in two. So what do we do? We stake it so it can’t wiggle. And that’s a very bad idea. Movement causes trunks to enlarge and strengthen. Trees that are firmly staked will never become strong.

Springs-Specific Gardening

Wall Germander (Teucrium chamaedrys)
Prickly Pear (Opuntia sp.)
Hyssop ‘Blue Fortune’ (Agastache)
Cockspur Hawthorn (Crataegus crus-galli)

There is certainly no shortage of advice when it comes to gardening. Everyone has an opinion, and when that fails, there’s the Internet. When you garden in Colorado, however, you quickly learn that much of the advice available doesn’t apply. It’s aimed at gardeners on the coasts, or the Midwest, or even the south—but not a place with harsh winters, false springs, sudden freezes, minimal rainfall, hail, gale-force winds… the list goes on and on. No wonder so many people give up and plant rocks!

Water Droplets on Leaves

Colorado State Univ. Field Day

As I was learning to garden, I repeatedly heard the “experts” telling us not to water in the middle of the day. The prevailing wisdom was that any water droplets on the foliate would act as little magnifying glasses, burning tender leaves. (Think of using a magnifying glass to start a campfire, and you get the idea.)

Then, we all learned that this was a gardening myth. Water droplets are too close to the plant tissue for sunlight to focus on the leaf and cause any damage.

Salvia in Red, White, & Blue

Vermilion Bluffs Sage (Salvia darcyi)
Silver Sage (Salvia argentea)
Salvia ‘May Night’

For today’s post, I’ve been considering perennials offer flowers in red, white, or blue. After all, we’re celebrating the Fourth of July this weekend. The various ornamental salvias not only come in these patriotic colors but they’re ideally adapted to Colorado’s challenging conditions. That’s why I’ve made room for at least one salvia in my Colorado Springs garden.

Committing Tree-icide: Water & Mulch

20200522_101626

(Don’t miss last month’s post about proper tree planting!)

Once we have the new tree in the ground, we want to do our best to help it not only survive but thrive. Knowing how dry our climate is, it’s natural to focus on providing enough water for the tree to become established.

A newly planted tree needs to be watered where its roots are. Those roots will be close to the trunk, which is why the landscapers set up their drip emitters to irrigate that area.

Pennies—Good for Thoughts, but Not Tomato Blight

Tomatoes - cherry Sunsweet @home LAH-001I recently ran across an article claiming that a penny can help your tomato plants fight off blight. Apparently, the reasoning goes like this:

  • Copper is known to kill molds, algae, fungi, and microbes.
  • Pennies are made out of copper.
  • Therefore, inserting a penny into a tomato stem (or burying it at the roots) will keep your plant from succumbing to diseases caused by molds, algae, fungi, or microbes.

Since I’ve lost tomato plants to Early Blight, a common problem in Colorado, I’d love for this idea to work. I have some pennies lying around; let’s put them to good use, right?

Well, not really.

Not Exactly Xeric: Plants for Wet Spots

Daylilies, Hemerocallis
Siberian Bugloss, Brunnera macrophylla
Turtlehead, Chelone oblique

Colorado gardening is all about saving water. Classes offer advice on how to group plants in your landscape according to their need for supplemental irrigation. Garden centers highlight species that tolerate drought. This year, Colorado Springs has placed restrictions on how we water our yards, and how often we are allowed to do so. We’re forever being told how to use less water in our gardens.

But there’s one part of our backyard that defies all the prevailing wisdom. It’s wet. It’s soggy. In the spring and during wetter summers, an entire hillside of rainfall drains through this spot. And if there’s no rain and we have to water our lawn? No matter how careful we are to avoid runoff, this one area still stays wet. (more…)

Probiotics for your Lawn?

I recently received this ad in the mail:

Lawn Doctor ad 09.47.51

While I noticed the baby crawling on the grass, the dog,  and the blurbs—“Better for you, your loved ones & your pets” and “50% less synthetics”—all designed to convey safety (with even more health references on the back), it was the word “Probiotic” that really caught my attention.

Probiotics are a hot topic. Research is constantly discovering how important our gut biomes are. But a lawn is not a digestive system. It looks impressive on the advertising, but is there really any point to putting probiotics on your grass?

Committing Tree-icide: Planting

20200522_101626

It’s spring. Perennials are emerging from underground. Spring bulbs are in bloom. The buds on are bare branches are bursting into leaves. Except for those that aren’t. A look around indicates that a lot of my neighborhood trees didn’t survive the winter.

Trees are not cheap. There is a significant cost when it comes to purchasing and planting a tree, especially one large enough to satisfy the HOA. It’s easy to blame their subsequent demise on Colorado’s notoriously capricious weather. Easy, but you’d be wrong. By far, the primary reason our new neighborhood’s trees don’t survive is improper planting.

It’s not the weather that’s killing the trees. It’s us.

Gardening Mania

Nursery display_Snohomish-WA_LAH_10.06.35-1

The calendar may claim that spring arrives in March, but those of us with high altitude gardens know that it really only begins after Mother’s Day. Even now, there is still a danger of a late frost, but at this point, we truly don’t care. We want to garden, and we want to garden now!

This is the dangerous season. We have so much pent-up enthusiasm just waiting to burst free that when the weather appears to be warm and settled (hah!), we can no longer control ourselves. Just look at the loaded shopping carts lined up (six feet apart) at the garden center check-out. I’m admit it, I’m as guilty as the next gardener—which is why I’ve learned to hand my wallet to my husband before entering a nursery.
