Autumn yard care can pay big dividends next year.
Topping or cutting back herbaceous perennials can help prevent the overwintering of diseases and insects. Mulching will help to prevent plants from being forced from the ground (but apply mulch after the ground is frozen). Watering lightly after applying the mulch will help hold it in place.
To prevent root damage during the winter, it’s important to have a reserve of moisture in the root zone for all plants in the yard. Fill the soil profile with water in mid-October or just before the ground freezes.
