sprinklertimer.jpgAutomatic sprinkler systems can make irrigating our landscapes (especially lawns) much easier, and they can also help us water more intelligently. In our area, we are usually encouraged to water lawns early in the morning or late at night. This is simple with a sprinkler system timer that can be set for any time of the day or night. Consistent watering is also important, especially during drought (a.k.a. now), and the timer easily takes of care of making sure your lawn is watered when you are away on vacation. In a previous post, I described rain sensors that can be added to your system so that it won’t run during or immediately after a storm. You can even find sprinkler controllers that incorporate weather sensors that turn the system off during high winds and incorporate local ET data to set sprinkler zone times. (more…)

Q: It’s winter. I can sit back, relax, and ignore my garden—right?

A: Not quite. The 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. In fact, if you listen, you can hear their cry 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. (more…)

Q: What can I be doing in my yard and garden in early spring?

A: Here are a few tips to get your yard ready for the growing season.

Lawns
Rake up last fall’s leaves, pine needles, thatch and other debris. Make sure the grass is getting adequate moisture to avoid grass mite damage and other dry turf problems.

Aeration plugs

Aeration is the best way to help your lawn thrive. It will reduce thatch and soil compaction, improve water and air absorption, encourage healthy root growth and control weeds. Remember to flag sprinkler heads before aeration. Plugs should be evenly spaced and two to three inches long, so watering well beforehand is a must. Aeration provides a great surface for fertilizing or over-seeding.

 

Fertilizer should be applied when grass is actively growing. Fertilize cool grasses such as Kentucky bluegrass, fescues and ryegrass in the spring. Wait to fertilize warm weather grasses such as buffalo grass, blue grama, and bermudagrass in midsummer. Colorado lawns prefer a fertilizer that is primarily nitrogen and includes some iron. Mulching mowers leave the grass on the turf and essentially provide all the needed nitrogen. (more…)
