Turf-Type Disease: Rust

We are seeing (and getting calls on) rust disease in lawns. The good news is that this particular disease seldom does long-term damage to the lawn, is non-toxic, and does not stain. It is a visual eye-sore though. The high humidity, [recent] lack of adequate moisture and may also indicate that your turf needs more nitrogen. Kentucky-bluegrass is a susceptible to rust disease.

Here’s a couple of tips to help your lawn if rust has targeted it:

Mow high. During the summer months your lawn should be 3-4″ high. Especially with the heat moving in this week, keep it high to shade out the crown of the plant. This will also help the soil retain moisture.

Water the lawn. Turf should have about 1″ of water a week for ideal growing conditions, ideally. If you choose not to water your lawn, it will go dormant and slow it’s growth. This is a normal reaction from the grass, though it is important to know what to expect. Also, if your lawn goes dormant it will begin to discolor and will not grow the rust disease off the blade of the grass as quickly.

Introduce nitrogen. If you are an active customer of ours, give us a call.
