· Learn how and when to harvest winter squash. Store winter squash in a cool, 50-55 F, dry location.
· Plant garlic cloves from mid-October through early November.
· Click here for a list of fall cleanup chores and good landscape practices.
· Remove vegetable plants from the garden once harvest is complete to reduce overwintering sites for insect pests.
· Protect tomatoes from early frost by covering the plants with a blanket or tarp.
· Rototill leaves, compost and/or manure into the vegetable garden to enhance the soil microbe activity.
· Limit pruning of roses to the heading back of excessively long canes to prevent damage from heavy snow loads.
· Cut back ornamental grasses in snow-prone areas once the foliage has dried down, otherwise leave them until spring and enjoy the vertical accent during winter.
· Plant spring blooming bulbs through early November.
· Planting trees and shrubs in the fall enhances root establishment.
· Dig tender perennials such as gladiolas, dahlias, begonias and canna lilies after the foliage has died down and store them in a cool, 45-50 F, dry location.
· Protect trunks of young trees from winter cracking by wrapping them with a white reflective tree wrap.
· Dig and remove annual flower plantings.
