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?


Villainous Voles

In last month’s post on “Who Ate My Plants?” I described the following scenario:

The heavy snowfall took a while to melt, but finally your dormant lawn emerges from under its frozen blanket. Last time you saw it, it was perfect turf, smooth and even. But now, it looks as if an army had performed maneuvers across your yard! Shallow furrows run here and there around islands of still-intact grass. What in the world?!


Rethinking Lawns

Useless turf_ColoSpgs-CO_LAH_8420Lawns—it seems we either love them or hate them. I was surprised when an informal survey of around 100 Colorado Master Gardeners revealed that only two people (2%) were very interested in growing lawns. Yet, half of the callers to the master gardener help desk ask for advice on growing turf grass. Clearly there’s a major disconnect here! Why are lawns so popular among the general public, yet loathed by many avid gardeners?

I unhesitatingly admit that a lovely lawn sets off the rest of the landscape. Flower beds, shrubbery, and other garden beds often look their best when they’re bordered by grass.


Feeding Your Lawn

What these manufacturers don’t take into account is that different parts of the country have different soils. What may be excellent advice for Pennsylvania or Maine may not work for Colorado. Unlike much of the north and east, the Front Range loses more water to evaporation than it gains in rainfall. Combine that with the native rock from which our soils are derived, and we typically have soils that are alkaline, high in phosphorus and potassium, and low in organic matter and nitrogen.


Bogus Bushes and Plastic Peonies

plastic-flowers-wilkes-2008aug28-lah-153It’s November. Bushes have bare branches, perennials are dead, dried stalks. Except for a few hardy groundcovers and various conifers (pines, junipers, and the like), the landscape is asleep. Except… wait! Are those daffodils in that flower bed? And does that window box really have bright red, white and blue flowers in it at this time of year?

There seems to be a new trend in town. Maybe it’s because our growing season is so short. Maybe it’s because water is expensive and limited. Maybe people are just tired of doing yard work. But whatever it is, it’s growing… or, rather, it isn’t.

People are landscaping with (gasp) fake flowers! (more…)

Winter Watering

_xg_20100316_lah_9826nefThe sky is bright blue, the sun is shining, the predicted high is well above freezing, and it’s been like that for months. Sounds like perfect weather—but not if you’re a plant. As I look out my window at my dormant garden, I can hear the plants crying for water. Everything is so dry! Desiccating winds have drained the last vestiges of moisture from exposed leaves and branches, and even the so-called evergreens are shriveled.

While the Midwest and Northeast get plenty of snow cover, and the Northwest gets rain all winter, Colorado gets neither. When the weather continues dry and windy, there needs to be enough water in the soil for our plants to replace what is lost to evaporation.


Xeriscape: Which Grass?

Now that you know why you want a lawn, and how big it should be, it’s time to consider what type of grass to grow.

Lawn_UplandIN_20090615_LAH_3607Kentucky Bluegrass still reigns supreme for a turf that can stand up to hard use. It spreads via runners, so it quickly fills in holes. (But beware. Those same runners have a tendency to wind up in the adjacent flower beds.) If you have children and/or dogs, this is probably your best choice.


Xeriscaping: Just Enough Lawn

What would happen if you turned on the tap and no water came out? We are accustomed to having water on demand, but here in the west, the truth is that we are slowly running out. As communities grow, increased demand on both surface water and aquifers will eventually lead to rationing and other restrictions. In some places, that has already happened.

Since landscapes consume far more water than household use, your yard is the best place to conserve.

Lawns are the thirstiest part of most landscapes, so let’s start there. Frequently, homeowners plant turf because they don’t know what else to do, or because they’ve always done it that way. A wall-to-wall carpet of grass might work in Virginia, but is it appropriate in Colorado?
