Time to aerate a lawn
Posted 16 May 2012 - 06:35 AM
What we'd like to know is:
Have you aerated your lawn in spring? Good results? Negative consequences? Lawn people sometimes tell us, "Oh no, never in spring." Yet we have seen it done at all times of year at golf courses and botanical gardens where we figure the practitioners should know. One of those told us, "Heck, the soil's such a sticky clay here that we aerate after just about every big event, since the lawn's get so much traffic, then." But IS there a best time?
Just took a break from the highway to stroll at the Royal Botanical Gardens in Burlington, Ontario and noticed scattered cores on the lawns there from light aeration. "Light" as in the lawn had not been criss crossed to pull a really large number of cores, as at a golf course where a green may look downright brown after a thorough aeration.
These are not goose poops, but finger-sized cores pulled from the lawn. They'll dry and crumble, and fall loosely back into the holes along with organic debris and any top dressing you applied. That creates lots of tiny, airy, rich compost pits in - a bonanza for roots.

Lawn aeration is the best way to keep excess thatch from developing, and restoring the channels that let air, water, and nutrients through to the grass roots. Leave the cores on the lawn even though it looks like a flock of geese have visited. After a few weeks cores will disappear. Aerating can not be overdone. It's absolutely one of the best things you can do to promote a healthy lawn.
