You’ve Overseeded Your Warm Season Lawn. Now What?
By now, most of you who are going to overseed your California or Arizona sod have either begun the process or have had your seed down for a few weeks. Today, I want to discuss what to do now that you have the ryegrass growing and cooler temperatures are on the horizon.
Getting your ryegrass up and growing is obviously the first step to a successful winter lawn, but what about maintenance? How can you make sure your ryegrass is strong going into the winter and you will have a full stand of ryegrass once the temperatures begin to drop into the 40’s at night? There are several key items associated with a strong winter lawn but early preparation should be high on your list.
I know you put down a starter fertilizer with your seed but let’s remember that fertilizer will move freely in a saturated soil. The new plant took up most of the nutrients from the starter fertilizer application but the residual affect is limited because you’ve been keeping the seed wet for the past few weeks. So what exactly does this mean? Basically, what I’m trying to say is that once you’ve had your ryegrass lawn in for 2-3 weeks I would advise getting a second fertilizer application on the grass.

Frequently Asked Questions About Overseeding Your Warm Season Lawn
Now that we’re into October it’s time to get the overseeding of your warm season grass process started. I wanted to pass along some of the most frequently asked questions during this time of the year.
When is the best time to start overseeding?
Ideally overseeding should be done when nighttime temperatures are consistently in the 60’s. Usually this will be in October. There will be some higher and lower than normal temperatures, but anytime during October is good.
How low do I need to scalp the grass prior to seeding?
Height of cut isn’t as important as opening the turf canopy. The shorter you mow the grass, the tighter the turf canopy will be which will result in the need to verticut more aggressively. I recommend not going lower than ½”. There is no need to take the lawn to the dirt or you will cause long term problems to the grass plant.

Winter Overseeding Your California and Arizona Sod Lawn
We often see overseeding your warm season California or Arizona sod lawn as a process that should be done in a weekend. For some this may be the most convenient way to prep but for others its okay to take a week or two to complete the process. Trying to knock it all out in one weekend can result in some really long days out in the heat. My suggestion is to slowly start the process now so in a couple weeks when the overseed window opens you’re ready to go and won’t be wasting your entire Saturday on the lawn. Remember that the ideal window is when nighttime temperatures are in the 60’s. We’re currently sitting in the high 70’s so I would expect a couple more weeks. To follow overseed instructions scroll to bottom of this blog.
Prepping for overseed is often a large ordeal, but starting the process gradually can eliminate a lot of headaches. I want to reiterate something I have said for the past few years. The height of the grass is not associated with a quality overseed. In other words, scalping the grass down to the dirt does not guarantee good results, but opening up the turf canopy does. The shorter you mow your lawn the tighter the leaf blades become making it harder to get the ryegrass seed into the plant. If the seed is lying on the surface it will be slow to germinate and much of the seed will be lost. The seed needs a base to grow out of, and getting inside the grass plant allows for perfect moisture, heat, and a solid growing medium. This is why it’s so important to have a good warm season grass base. If you have a new lawn or a weak summer lawn it can have a direct impact on your overseed. The seed will establish much faster inside a healthy grass stand than it will on bare dirt.

California and Arizona Sod Tips: It’s ALMOST Time to Overseed Your Lawn!
With the recent heavy rains and slightly cooler temperatures no doubt people are thinking about overseeding their California and Arizona lawns. While the calendar says September 18th and you will surely see people overseeding, I suggest you wait a few weeks. Follow my California and Arizona sod tips for a beautiful lawn. Overseeding does not need to be a one day process. You can begin the process a little early. Then, when temperatures are in the 60’s at night, you will just need to give your lawn one last haircut, drop the seed and begin watering.

Getting inside the grass plant allows for perfect moisture, heat, and a solid growing medium. By looking at my last statement you can now understand why I say without a good warm season grass base (used on popular California and Arizona lawns) you will most likely have a poor ryegrass season. The seed will establish much faster inside a healthy grass stand than it will on bare dirt.

Summer Tips for Your Sod Lawn in Arizona and California
Summer is wrapping up, the kids are heading back to school, and I’m sure you’re ready to come out of hibernation. While the summer heat is far from over in Arizona and California, it’s starting to become tolerable outside. With the slightly cooler mornings it’s time to get back outside and get your lawn ready for fall. Most people start thinking about overseeding their California and Arizona sod in September, but ideally you wouldn’t start the process until October when nighttime temperatures get into the 60’s. Between now and then there are some important steps you need to do to get your lawn ready and to save some headaches down the road.
Between May and September you probably noticed your lawn has grown at twice the rate it does during the winter months. Warm season grasses love the warm, wet weather. Most people thought the hot weather would keep the grass from growing well, but remember warm season grasses optimal growing temperatures are between 90-105 degrees. During this season any of your weaker areas should have filled in with the warm season grasses runners. These spots can be slow to fill in during the dry, hot days but as soon as the humidity kicks in the grass really takes off. If you still have large open spots I would suggest picking up a few rolls of sod and patching them prior to overseed. You don’t want to seed directly into the soil.

Fall Overseeding and Your Lawn
The days are getting shorter and the heat is starting to die down a little as we enter the fall season. With fall comes the onset of overseeding in many parts of the country and the West Coast is no different. For those new to overseeding let me give you a brief definition. Overseeding is simply the process of seeding a cool season grass into your warm season turfgrass in order to maintain winter color. This is not a mandatory process if you have grass, but it is one of the options that are out there for homeowners and professionals.
There are a few options during the fall months to take care of your lawn, and without question the most popular is to overseed. Outside of overseeding you have the option of using turf colorant such as Endurant to give your dormant grass a nice green appearance. Or you can just let your lawn go dormant for the winter months (brown can be the new green!). There is no right or wrong approach, so decide what you would like to do as the temperatures begin to drop over the coming weeks.
If you will be letting your lawn go dormant it will stay fairly green until the first hard frost which is around Thanksgiving and will start to green up in late March. If you have a paspalum lawn you can usually get through the month of December with a green lawn and it will start greening up in early March.

Thinking About Overseeding Your Warm Season Lawn?
With the heavy rains and slightly cooler temperatures we had this past week no doubt people are thinking about overseeding. By the way, if your sprinklers are still set to on, turn them OFF. While the calendar says September 11th we’re still a few weeks away from having temperatures in the optimal window. Overseeding does not need to be a one day process. You can begin the process a little early and then when temperatures are in the 60’s at night you will just need to give your lawn one last haircut, drop the seed and begin watering.

Evaluating Your Summer Lawn
As we move through the dog days of summer in California and Arizona, now is a good time to evaluate your turfgrass lawn. The summer is the optimal time to grow warm season turfgrasses so it is important to get good growth before the end of the season. The golden rule is that all warm season grasses need to have 100 days of growing without any competition in order to maintain their health. That is 100 days without any lingering ryegrass in the way. Think back to when the ryegrass was completely out of your lawn? Was it June or did it hang around until July? If you didn’t transition it by mowing lower and verticutting then most likely you still had some ryegrass until the humidity increased and wiped it out in July. Read the rest of this entry »

I Overseeded My Lawn–Now What? Tip of the Week/College Football Week 6
I had the chance last week to lie around the beaches of south Maui, and that gave me plenty of time to check out how great the paspalum looks on the lawn areas at the hotels and golf courses, come up with some new things to write about overseeding, and assess my horrible college football picks so far this season. I know I have covered the basics of seeding and fertilizing, but since these steps are so vital to the success of a winter lawn I am going to tell you how to push the growth and fight off the loss of color when the frost hits.
