In spring we mulch to suppress weeds, retain soil moisture, and regulate soil temperature. But did you know that mulching now is just as important?
Throughout winter, the repeated periods of freezing and thawing can damage plants and cause them to heave out of the ground. We therefore mulch to keep the ground frozen, so that plants can remain dormant through the winter months.
The best time to mulch is after the first hard freeze – but before any heavy snowfall. A layer of at least 2-4 inches should applied around plants and gently pulled back from any trunks or stems to allow for aeration.
Mulch will protect the ground from the warmth of the sun during mild spells and will conserve whatever moisture remains in the soil.
