For most parts of the country spring means a return to warmer temperatures and usually some good rain storms. For the desert southwest this typically means hot temperatures and the occasional rain event. We were lucky enough to get some late season El Niño storms this month which will have a nice impact on our warm season grasses.

The transition season has officially begun and over the next month you will start to see your underlying warm season grass start to push out the winter ryegrass. The hot temperatures will start to take their toll on the ryegrass and it will start to die out. It’s not uncommon to start to see dry patches emerge in your lawn that looked perfect the week prior.

As much as it may pain you to see sections of your beautiful lawn start to die back remember this is a good thing. Sections of your lawn will always dry out before others areas simply because of the soil texture, compaction, or sprinkler coverage. It’s important to rule out sprinkler issues and if it is merely a transition dry spot rest easy. For these spots I recommend taking a hard toothed rake and rake up the dead ryegrass that lies on the surface. This dead material is shading out the bermudagrass down below and preventing it from getting water and sunlight. Keeping your lawn mowed below ¾” during this time of the year and power raking or verticutting will also help remove dead material from shading your summer grass.

We all know that transitioning from ryegrass back to a warm season grass is difficult (especially for California and Arizona sod), but throw in some cooler than normal weather and now you have a battle. Every year the producers of ryegrass seed seem to make their seed a little more heat resistant in search of that year round turf. The problem with this is that we’re shortening the growing window of our warm season turf. Not to mention that cool season grasses in the desert areas use much more water than the underlying warm season turf. The solution is to aide your lawn in transition, and to get your lawn free and clear of ryegrass in the next couple weeks.

Before I go into techniques to remove ryegrass I want to make a couple points about how the average lawn looks at this time of the year. We all love our winter lawn for its color, texture, and feel, but it’s important to remember that it puts agronomic stress on your lawn. When you have two different grasses competing for nutrients, water, and sunlight you’re bound to have an “ugly period.” The turf world refers to this as the transition period. This is the period of time when the cool season grass is starting to die off slowly and the warm season grass is trying to emerge. What creates the ugly period is the competition.

(BTW…this beautiful turfgrass is NOT going through an ugly stage!)

Since the Michigan game was a complete sleeper over the “powerhouse” known as Delaware State, I decided to check my inbox and see what people are asking questions about…..

Over the weekend I had several people wondering what the best option for grass is if they don’t want to overseed. There are a couple of choices.  Read the rest of this entry »
