Changes in Water Restrictions in California
We have all read an article or two lately about the need to cut back on water used outdoors for lawns, trees, and shrubs. We are in a time when water supply is low, and we are caught between trying to keep our homes cooler by having a lawn and using too much water to keep it green. There will always be two sides to this issue as some see lawns and plants as a waste of water and others understand the benefit to the environment. As is the case in politics a blog post or article is not going to change one’s mind one way or the other but being opened to change and learning from each other will help us find a middle ground. Today I am going to talk about ways to reduce water for your turfgrass while keeping the grass healthy, and still providing the benefits to the environment.
Grass selection is becoming more and more important. Let us start by examining the difference between warm and cool season grasses. Here in the southwest you can expect to use 30% more water by using a cool season grass when compared to a warm season grass. Cool season grasses grow best between 60-75 degrees whereas warm season grasses grow best between 90-105 degrees. Picking a warm season turfgrass for your area can save a significant amount of water and allow you to curtail water use longer during hot, dry periods. Swapping out a tall fescue lawn for a drought tolerant bermudagrass is much cheaper than you think and it will save water and put money back in your pocket.
The next part of grass selection is determining the right warm season grass for you. Breeders have been working overtime for years to come up with more drought tolerant grasses and they have been very successful. Some of the grasses on the market right now for reducing water are Kurapia (best drought tolerance), Tahoma 31 (second best), Tiftuf (3rd) Santa Ana, Paspalum, and Zoysia (coming soon to WCT). Kurapia is a ground cover that can be maintained on 50-60% replacement of evapotranspiration and even less if you want to slow the growth and put the grass into a state of dormancy during the hot summer. Studies have shown Tahoma 31 to use slightly less water than Tiftuf its closet competitor in the drought market and 20% less water than older bermudagrass varieties. Selecting the right turfgrass will enable your lawn to use less water and maintain drought tolerance through the hot summer.
How much water does grass need to survive? This is a loaded question, and you will get several different answers but on average 1.25” of water per week during the hottest part of the summer will keep your lawn healthy, thriving, and growing. Can you water less than 1.25” and have a good lawn? Absolutely! You could maintain your lawn with a once-a-week deep irrigation cycle during the summer months to keep the plant healthy and alive. The drought tolerant varieties will put your lawn into a state of pseudo dormancy, but the turf will still provide the same environmental benefits. I know for many having a green lawn is important but sometimes its not possible based on available water. In this situation I advise using a product like Endurant Turf Paint to give the lawn the desired color during periods of water reduction. Since the lawn will not be growing much the paint should last 45-60 days.
Raise your mowing height during the summer. The shorter you maintain your lawn, the shallower the root system will be for the plant. Most warm season grasses can be maintained between half and inch and one and a half inches. These are the optimal ranges but do not be afraid to raise the height to two inches and save even more water.
Water infiltration is extremely important. If your soil is a hard pan and water sheets off the ground every time you water, there is some work to do. Grass loves a deep watering which can happen all at once or broken up in the cycle/soak method. This means running 10-15 minutes and then letting it soak for an hour or more before running the second half of the cycle. If you cannot run more than a few minutes of water without runoff its time to aerate and open the soil. This will relieve compaction and allow water to freely get into the soil.
Irrigation systems save time, water, and money. Putting in a smart timer that calculates evapotranspiration and tests soil moisture will help keep water use down and drastically lower your budget. These smart devices calculate real time weather, plant needs, and soil data. You can set them to use 70-80% of ET to keep your lawn growing. Many cities offer free irrigation clocks and soil moisture monitor tools so check with your city and see what is available.
There are so many great options on the market right now to save water and allow you to have a healthy lawn. Remember that a lawn does not have to be bright green to be healthy. No one wants to give up their lawn and no one will have to if we all use some conservation methods. If you have any questions on any varieties send me an email and I will be happy to help you out.

Spring Cleaning Your Outdoor Space
The sun’s out, but it’s not too hot yet – now is the perfect time to get your home, garden, and outdoor spaces ready for spring. Here are some simple steps to getting the spring cleaning done.
- Clean, clean, clean. Wash windows and floorboards, dust off any cobwebs, sweep surfaces, and clear away any debris from fallen leaves and trees. Power wash your patio or deck. Wipe down patio furniture. Clean or replace any outdoor furniture as needed.
- Update your green spaces. Mow your grass, trim your shrubs, redefine garden beds, make sure your natural grass is healthy and in a good routine for watering and mowing. Have fun with it – add pops of color in planters and herbs to your garden for cooking.
- Aerate your lawn, if necessary. If your lawn gets heavy traffic, such as lots of running and playing in the same spot, this can cause soil compaction. A lawn aerator creates openings in lawn turf that allows water and air to penetrate the soil and reach the grassroots. You can rent a lawn aerator at a big box hardware store, or, if you have a small lawn, use a hand aerator to do it. If you must aerate in the spring, consider doing it around Memorial Day, after weeds have started growing but before they go to seed.
- Weed your lawn. If you prefer weed-free lawns, spring lawn care is as much about weed prevention as it is about fostering healthy lawn growth. Depending upon whether a weed is annual or perennial, you will use either a pre-emergent herbicide or a post-emergent herbicide.
- Service your lawn mower. Spring means it’s time to get out the lawn mower and make sure it’s in working order. Start it up – stubborn start-ups are a sign that it might be due for a tune-up (mowers should be given tune-ups once a year). If your lawnmower needs more than a tune-up, then consider getting a new one. Among the key tune-up tasks is sharpening the mower blade. A regular sharpening will ensure the blade severs, rather than tears, the grass, leading to a nice green lawn rather than one with ragged brown tips.
Once your outdoor space is ready, get outside and enjoy this beautiful spring weather! For more information visit https://www.westcoastturf.com
