Over Seeding

Giving you that lush, dark green winter lawn that's the envy of your neighbors is our goal!

Many factors go into having the perfect winter lawn as well as ensuring you have a healthy summer lawn the following season.  I have a Bachelor of Science Degree in horticulture with a specialization in Turfgrass Management.  I keep up to date on the latest research from the University of Arizona and other southern schools that conduct research studies on Bermuda Grass and over seeding.  I've done it on a very large scale on courses here in the valley, and now I want to put all of that experience to work to give you an outstanding winter lawn!

Here's what we do to give you the perfect winter lawn....


Scalping the right way is key to a great over seed, it's the foundation. It's also critical to the health of your Bermuda Grass.  Take too much and the Bermuda will be slow to come back in the spring.  Take to little and good seed to soil contact isn't achieved resulting in a poor, thin winter lawn.  Some landscapers will use dethatching machines to speed up the process.  Dethatching injures the Bermuda plant.  Studies have shown that this should never be done unless there is at least 45 days of active growing weather for the Bermuda to recover.  Obviously at the end of the summer growing season there's no time to recover and this will result in a very slow to fill in summer lawn the following year.

Quality Seed

Many landscapers will use the cheapest seed they can find from the local home improvement store.  Beware of companies that use Annual Ryegrass.  While this seed is quite a bit cheaper than Perennial Ryegrass, it is quite a bit less hardy, thinner and usually a lime green color.

We use a premium 3 variety Perennial Rye blend from a reputable supplier.  Why a 3 variety blend?  Professional Rye blends are specifically selected for over seeding in the desert southwest.  Ryes that work best here may not be the best choice for overseeding in other southern, more humid climates or for seeding a new lawn in the midwest.

Each variety is selected for a specific purpose.  One that germinates quickly so you have a bare, brown lawn for a shorter period of time.  One that thrives and grows in cooler weather so the lawn still is lush and green through the cool, wet months of December and January.  One that performs in warmer weather to keep your lawn looking great all spring long!


We include an application of starter fertilizer to get your winter lawn off on the right foot!  Starter fertilizer contains high amounts of Phosphorous wich is an essential nutrient in the soil that is immobile.  While nutients such as Nitrogen and Potassium move freely, Phosphorous is held to soil particles, which is why a starter fertilizer "floods" the upper soil profile where young roots can reach it.


It is critical that the seed not dry out.  This must be balanced by not allowing puddles and run off to occur which will move the seed.  Not only do we set up your irrigation schedules correctly for grow in, we take the time to observe how much your sprinklers put out in a given time and how well the soils takes it in.  No two sites are exactly the same, and simply blasting it with water can lead to very poor results.


Over seeding is done during the last weeks of September and the first weeks of October.  A discounted rate is given if you book before September 1st and our regular service customers recieve highly discounted rate.
