Summer comes early

It didn't take long. One weekend of higher temperatures and increased humidity mixed with an overall lack of precipitation. The result? Heat stress, brown patch and summer patch.

It's the type of conditions we usually see on lawns late July, or early August. Yet here it was not even June and it seemed almost every lawn was suffering from one or the other.

This is precisely why we preach the importance of proper cutting, (3" high), and watering, (1 to 2 inches per week), when temperatures go north of 30 Celsius.

In the case of turf diseases like brown and summer patch, pounding your grass with water is only going to add to the problem. Make sure watering is less frequent, mowing blades are sharp and the thatch layer has been aerated. It is also important to stay away from quick-release fertilizers. Remember in Ontario fungicides are not an option and would be a very expensive remedy if they were.

Slow and steady wins the race here. Over time a resilient lawn will correct itself with proper  techniques and return to the green you expect without damaging your wallet.
