Welcome to Summer!:
I hope you have a safe and fun Memorial Day weekend. The unofficial start of summer has arrived, but the temperatures don’t feel like it. This Spring was one for the record books in regards to rain and cool temperatures. I have already seen some Red Thread in lawns. The best cure for Red Thread is to make sure the lawn is fertilized very heavily on regular intervals. You may need an application every 3 weeks if you have it severe enough.
Make sure you are mowing the grass on a frequent enough basis that you never cut off more than 1/3 of the blade of grass. For example, if you mow the lawn at 3 inches high, you should cut the grass when it has grown 1 inch and is 4 inches high. With the growing conditions we are in now, there should be no more than a week between mowing. Your lawn might grow an inch in one day!
The cool, wet spring is going to lead to a lot of Apple Scab and Cedar Apple Rust. If your property has Crab Apples, Cedar, Junipers, Hawthorn, or Pear trees, you should consider treating them now. We are at the end of the window for the first treatment to prevent these diseases. Pine Needle Scale is also emerging and now.
