It’s Time To Tuck The Garden In For The Winter
As the days grow shorter and the nights cooler, it becomes increasing clear – we”re going to have another Wisconsin winter. And just as northerners have to check the anti-freeze in the car and put up the storm windows, we”re going to have to winterize the lawn and garden.
Susan Mahr, coordinator of the Master Gardener program at University of Wisconsin-Extension, says autumn chores in the lawn and garden can get lawns, trees, shrubs and perennials off to a better start next spring.
She offers the following checklist for tucking everything in for the winter. Autumn lawn care: Grass grows more during the cooler fall weather. Through the fall, mow turf grasses 2 to 3 inches high to reduce weeds. But lower the blade to 1.5 to 2 inches for the last mowing of the season. Shorter grass provides less shelter for meadow mice and moles. Make sure to trim grass around tree trunks, shrubs and perennials for the same reason.
Protecting trees and bulbs: If you have young trees, protect the trunks from rodent and rabbit damage with hardware cloth. Tree wrap will protect the trunks of young and smooth-barked trees from “sunburn.” Sunburn happens when the sun warms and thaws the bark on the southwest side of the trunk. Cold night temperatures then freeze and kill the cells on that side of the tree. Sunburned bark will peel later. To protect the roots of recently planted trees, spread mulch two to four inches deep around base as the soil freezes.
Roses: In late fall (mid November), prune canes back to 10-12 inches and mulch the plants.
Perennials: Remove excess dead material, but leave about 6 inches of stubble to trap insulating snow. Fall is a good time for lifting, dividing and planting many perennials, especially those that bloom in spring and summer.
Tender bulbs: Gladiolas, dahlias, some lilies and other tender bulbs won”t survive a Wisconsin winter. Dig them up and store them in a cool, dry place.
Leaf clean-up: Rake up fallen leaves. They make great compost, but they should be chopped up first for faster decomposition.
Tools and equipment: Clean and oil garden tools to prevent rust in storage. Drain the gas from mowers and other power equipment. Store fertilizers and chemicals properly to prevent degradation. Try to use up chemicals during the growing season so you won”t have to store them.
Plant hardy bulbs: This may be the most enjoyable and rewarding of autumn garden chores. It”s time to plant tulips, narcissus, crocus and other hardy bulbs that will help you welcome spring next year.
