Getting Your Lawn in Top Shape During Spring Transition
**Due to California and Arizona’s statewide shelter at home orders because of the coronavirus, West Coast Turf is carefully and responsibly continuing to operate using heightened hygiene and social/physical distancing rules to maintain the health and safety of our employees and customers.
We are monitoring available information and are able to continue to supply sod since it’s an agricultural product, and supply hardware stores, nurseries, and construction, which are listed as exempt from the order.
All orders must be prepaid on the phone or website. Orders will be delivered without any contact, and know that we appreciate and value our loyal customers.
Please be aware that this could change at any time if further clarification is given by either State. We are open and here to help you with your turfgrass needs.**

A lot of us have some extra time at home right now, and are spending more time out on our California and Arizona lawns.
There’s a renewed appreciation for nature and the outdoors. And, the sight of green grass and the smell of fresh cut grass has proven to be beneficial to our mental health and help curb anxiety–that’s ALWAYS welcome–especially now.
Taking care of your lawn can be productive, therapeutic, and something you can do alone, or with someone else safely and socially distant.
Let’s talk about some things you can do right now to make sure your lawn transitions properly this spring……
Spring Transition
As the temperatures begin to rise it’s a good time to look at your lawn program. Did you overseed your warm season lawn or allow it to bounce into dormancy (*jump to the bottom of the page for a dormant lawn)? Either way there are some important items to remember so you have a healthy, lush lawn all year long. It’s still a little early to see the full effects of transition. If you plan right your transition will be seamless.
Transition typically occurs in April and May, but being proactive now can speed up the process. For anyone that’s gone through a spring transition you’ve probably learned the worst mistake is to start too late.
Here is a step by step process that can be implemented into everyone’s program over time. Some people fear putting down an overseeded lawn at this time of the year but there is no need to worry. The roots of the ryegrass actually help the grass knit into the ground quicker and as the temperatures warm up the ryegrass easily transitions out. I will note that you don’t want to buy sod with 3” ryegrass. But we keep our turf at ½” to ¾” at this time of the year so it makes for an ideal transition without any fuss.
1. Gradually lower you’re mowing heights to reduce the turf canopy. Warm season grasses are not shade tolerant and excess ryegrass provides shade. No need to scalp the lawn, just lower the height down and begin to thin out the grass.
2. Lightly verticut the lawn to open up the canopy and let sunlight into the grass below.
3. Be careful of fertilizer rates at this time of the year. Stick to slow release products. You want to put a pound of nitrogen per 1000 SF down when you make this fertilizer application. The first number on the bag is nitrogen and it is listed as a percentage. For example the 21-7-14 is 21% nitrogen. A typical fertilizer bag weighs 50 lbs so 21% of the 50 pounds is nitrogen. In other words you have 10.5 pounds of nitrogen in a 50 lb bag. Since the goal is apply one pound of nitrogen you would use the following formula:
1 pound of nitrogen / .21 (percentage of nitrogen on the bag) = 4.76 pounds of product per 1000 SF will yield 1 pound of nitrogen.
4. If you have standing water it is a great time to aerify so you can help air and water better infiltrate the soil.
5. Increase your mowing frequency to two times per week.
6. Gradually back off the water next month to stress out the ryegrass when soil temperatures reach 64 degrees (around mid-April). Turning off the water completely will stress out the warm season turf and ryegrass so this is not the optimal approach. Use 60% of your normal water rate.
7. When soil temperatures reach 64 degrees apply Soil Burst 4-4-2 at 15 pounds per 1000 SF to give the grass a jump start on the year. A second option to this is to use ammonium sulfate 21-0-0 at 5 pounds of product per/1000 SF.
8. Fertilize with 1-2 pounds of nitrogen per 1000 SF monthly over the summer. You can use any combination of the products I listed above as well as several others to help you achieve your goal of a perfect lawn. For a more accurate analysis on other nutrients you can send soil samples into a lab for results.
Once you’ve followed all of these steps you can set your irrigation to run 3 to 4 times per week for 20-30 minutes at a time. If you can’t water for 30 minutes without getting runoff it is okay to break it up into a cycle/soak.
Non-Overseeded Lawn
By now you’re probably tired of seeing the yellow/brown turf and want to give your lawns a jump start. While it’s still too cool outside to get your California or Arizona lawn growing, you can get it to green up. The enemy of a dormant lawn is the cool nighttime temperatures. You can gradually begin to ramp up your water and fertilizer program.
Let’s start with how much water you need to put on your lawn. The soil temperature is still cool enough that watering 1-2x per week for 10-15 minutes is plenty. It’s good to keep the roots nice and moist and allow the plant to start to thrive. Over watering right now has potential to cause disease in your lawn. When the daytime temperatures get into the 90’s you can increase to 2-3x times a week and slowly ramp up to 3-4x a week by May.
Bringing the grass out of dormancy can be accomplished several ways. I like to do so with products such as 11-52-0, 15-15-15, or Soil Burst 4-4-2. Putting down excessive nitrogen right now will not benefit your bermudagrass since it’s not warm enough to actively start growing. These products will help green up your lawn and slowly bring it back without a jolt of nutrients. Adding too much fertilizer could put the lawn in shock if we were to experience one additional cold snap over the next month. You don’t want the grass to use all of its reserves in the plant too early only to get shocked by some cold weather.
Be sure to check all of your sprinklers and spray patterns. There is a good chance some sprinklers broke and nozzles were damaged over the winter. These are very simple fixes and can be done for just a few dollars. Having the correct spray pattern and coverage can save you money all year long.
