IT’S SEEDING TIME AGAIN IN MANY AREAS OF THE COUNTRY

Prep for overseeding in the Desert
During the month of October, golf courses in the sunbelt areas of the country are faced with a huge task. Overseed, yes overseed. This process is different in each region and requires a ton of work for it to be successful. In the desert regions, winter nighttime temps drop into the 30’s and 40’s and warm up into the 70’s during the day. These temp changes make the Bermudagrass go dormant and turns it brown. Overseed is a must during the winter months when golf demand is at highest point of the year. The goal with a desert overseed is to completely cover the bermudagrass with ryegrass. Period. Any areas of bermudagrass still thriving in the fresh new ryegrass stand will stick out like a sore thumb in December. These courses will be growing this new crop for the next 7 months then they flip the switch and grow bermudagrass for the rest of the year. I wish it was that easy. These superintendents work magic during this process.
Verticut prep of fairways for overseed
In Florida, I call this seeding process interseeding. The goal here is to have 60% stand of bermudagrass and a 40% stand of ryegrass. Only areas in north Florida have nighttime temps in the 30’s and the rates might be higher. South Florida has only a hand full of cold days a year that knock back the bermudagrass and seed is not needed. With seed comes the stripes. Many clubs that push for green at any cost want to see a bang for their buck. “Hey Sup stripe it up baby”. Somehow they think that your growing bentgrass and they want the place to look like their club up north. Just relax and play it as it lies.

Overseed or Interseed this winter. What are you going to do?


This time every year superintendents decide if they are going to drop seed or not. Here in South Florida, after a rough cold winter last year, I think many golf courses might just do it. I don’t like to call this process overseed here in South Florida, I call it Interseeding. Interseeding of what you may ask. If you have a new ultra dwarf bermudagrass on greens and the golf course is located south of Jupiter, Florida, I say no way. If the golf course is located in the desert of California or Arizona, I say you better. I worked at PGA WEST, in La Quinta, CA and we overseeded everything on each of the 9 golf courses. We had to make sure that every bit of bermudagrass was covered with seed. If it was not covered you would see the brown bermudagrass come through and look bad all winter long. It gets so much colder at night in the deserts and frost is more common. Last winter in Miami, we had 4 mornings of frost and the grass went off color but did not go brown. The Palm Beach area was not so lucky. They had many more days of cold weather and cloud cover which made growing turf very difficult. I have made the call to interseed my driving range tee only this year and that is it. I want a 40% ryegrass and 60% bermudgarass stand of turf. That will work great for us and help with the small size of the range tee. Golfers will have grass to hit from. What are you going to do?
