A couple weeks ago I put out a post on overseeding and now that we’re through September it’s time to get the process started. Click here for the previous post on overseeding for full instructions. In today’s blog 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. Typically this will be the month of October. Obviously there will be some spikes and lower than normal temperatures during this period but anytime during October is good.

How low do I need to scalp the grass prior to seeding?
The height of the grass 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. Read the rest of this entry »

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.

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.

By now most of you are probably doing what I do all day and that is watching grass grow. If you threw down seed to overseed your warm season lawn in the last couple weeks it surely has sprouted,and should be filling in quite nicely with our weather.  It always amazes me how quickly ryegrass grows at this time of the year. You can check your lawn before you leave for work in the morning, and by the time you get home it has grown a ½”. It usually takes about 7-10 days to get your lawn really going, but once it does you will start to see the grass tiller and fill in any voids in your 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 11^th 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.

Prepping for overseed is often a large ordeal, but starting the process gradually you can eliminate the headaches associated with trying to get it all done in one afternoon. 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. By looking at my last statement you can now understand why I have said without a good warm season grass base 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. Read the rest of this entry »

We’re getting closer to the overseeding process! I am sure many of you reading my blog have started to see perennial ryegrass arriving in stores by the truck full, but we are still a little early. It isn’t too early to start some of the initial prep work, but it is still a little hot to drop seed. I realize that some of you won’t have a choice in the timing of overseeding, but if you do have a choice it is best to wait. Today’s blog is going to give you 10 easy steps on how to overseed and establish a great lawn for the winter. I have also attached a short video on doing so. www.youtube.com

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.

The weather is finally starting to cooperate, and we are in prime overseeding season from now till early November.  It appears that the night time temperatures will start to drop into the high 60’s by mid week and the day time temperatures will be in the high 80’s.  It has been a long hot summer (as they all are!), but this one seemed particularly brutal to me.  Read the rest of this entry »

As we get into the fall people are starting to get that itch for the ryegrass and the nice color that goes along with it, so I’m going to answer some “frequently asked questions” related to overseeding, general sod, and seasonal issues.  I will post an in depth overseeding manual as we get a little closer to the season and when the temperature decides to dip below 114 degrees.  You and I also know that with the start of the Michigan Football season around the corner there are more important things than overseeding, so maybe I will discuss a little college football also.
