Hot Weather and Lawns...

The dog days of summer are upon us and everyone's lawns are showing it. Lawns that are not irrigated are beginning to slow down in growth and some are showing signs of going back into dormancy. As this occurs there are a number of things to keep in mind.

1. First of these is that Bermuda-grass can and will go into a semi-dormant state when it runs out of water and it gets hot, simply to protect itself from the stress of the hot weather. The bermuda-grass will come out of this as soon as consistent rain and cooler temperatures arrive.

2. Fescue on the other hand is a cool season grass that does not have the same mechanisms of drought control that bermuda-grass does, and is much more prone to dying out during hot weather. This is why you need to try and keep your fescue well irrigated, even so some fescues will stop growing and may regress just due to the hot weather.

You can help both your fescue and bermuda-grass lawns through the dog day's of summer by simply raising your mowing heights, as the longer leaf blade you have the more cooling area your grass has. Also be smart about when you irrigate as irrigation that is put on during the heat of the day is easily lost to the atmosphere by evaporation or wind. Instead try to apply irrigation during the evening hours when evaporation rates are lower, and often times the wind is dying down allowing the water to hit it's intended target.

Keep it green,
