A Few Thoughts on Water Conservation

Kris Horvath

Let’s all pray for rain in the valley and abundant snow in the Sierras in the upcoming weeks. Water is a precious commodity that we can’t afford to waste and can’t live without. I don’t claim to be fount of all knowledge on irrigation, but I can recommend a few things one can do to be more efficient in the use of their irrigation water in the landscape. I love lawns and so I am not inclined to always jump at the idea of removing turf from the family landscape. Actually, I would be looking for ways to keep my lawn and landscape healthy with the properamount of water at the proper interval to encourage deep irrigation and deep healthy roots.

Three areas come to mind and one of them is planting the correct plant material for the right soil, exposure, climate, etc. Beyond that, I think one is crazy not to look into smart clocks (irrigation controllers) and more precision delivery from the newer emitters. You can make your controllers “smarter” with these clocks that take into account the soil texture, zip code, daily temperature, rainfall, slope, plant material and so on. The addition of a local mini weather station or internet-based weather input will allow the amount of time needed to run each valve to be adjusted up or down each cycle. This will go a long way to increasing efficiency (possibly 30-40%) over the common method of turning the clock on in March and turning it off in late October with no regard as to the actual needs of the plants.

Finally, there is the choice of irrigation emitters themselves. There are nozzles like the MP Rotators and Precision Series Nozzles that are much more efficient in both their uniformity of coverage and the rate of delivery. With a larger droplet size and slower rate of delivery one can greatly increase the uniformity and significantly reduce the chance of runoff.  

Check with your local irrigation supply house and see what advances have been made in the past few years or call Aqua Man Irrigation Solutions at 559-475-7777. Upgrades will pay for themselves in your water bill, your plant’s health, and conserve water. It’s the smart thing to do.

Crabgrass Prevention Now!

I really r..e..a..l..y don’t like crabgrass. Crabgrass is a pesky annual grassy weed that loves irrigated lawns here in the Central Valley. It gets really large and very apparent in lawns by mid-summer, but by then it is much more difficult to control. Left unchecked, crabgrass can rapidly take over a nice lawn in a matter of a few years.

Here’s the problem. You will not find an effective product for controlling existing crabgrass or dallisgrass on your store or nursery shelf. MSMA, found in Weed Hoe and Trimec Plus, is no longer available to homeowners and was the only product that actually worked on the removal of unwanted crabgrass unlike the products offered now. There are several products now on the market for homeowners for post-control of crabgrass and all contain quinclorac. I have not had good success at all in the Central Valley of California getting any significant control using these. Maybe you will be lucky and make one of them work, but my guess is that they won’t and you will be out both the time and expense you have invested.

Prevention is the key to crabgrass management especially without a reliable product for managing actively growing crabgrass plants. Ideally, a pre emergent herbicide should be applied at the proper rate prior to Valentine’s Day. There are a number of products out there (some better), but unless they are applied before seed germination at the right rate and uniformly the results could be less than desirable. Weed Man actually applies three applications to ensure better results.

What is the future for crabgrass control? There are some products in development for professional use only. As of today, there are very limited options even for the professional. New products are not as user-friendly as they are specific for warm or cool season grasses and not both. A sharp knife works well, too unless you have hundreds or thousands of plants.

Why risk your lawn to crabgrass invasion when the cheapest and most effective solution is prevention with pre emergent herbicides. A pre emergent must be applied before seeds start to germinate. Correct timing and rates of a quality pre emergent ensure great results. Have your lawn treated either by yourself or a professional before Valentine’s Day.
