Welcome to winter, one of the best seasons for gardeners. You have time to plan, prune, and enjoy those houseplants that don’t get much love during the outdoor growing season. Make the most of your winter gardening with these dos and don’ts from Chicago Botanic Garden experts.
DO prune your deciduous trees. From mid-November to mid-March, it’s much easier to prune because you’ll be able to better see a tree’s branching structure and there is less chance of transmitting diseases from one plant to another.
DON’T prune conifers. Needled evergreens can be pruned in late winter or early spring, before growth begins. Arborvitae should be pruned during spring and early summer.
DO water newly planted trees and shrubs that might be in the path of salt spray from salted roads during periods of winter thaw. Consider wrapping vulnerable trees to prevent damage from salt and extreme temperatures.
DON’T overwater houseplants. Because of shorter days and reduced humidity, most houseplants aren’t in an active growth phase, so they’ll require less water and fertilizer.
DO keep houseplants away from cold drafts, radiators, hot air vents, and cold windows. Plants growing in sunny east- or north-facing windows may benefit from being moved to a southern or western exposure for winter.
DON’T try to remove ice or snow that has frozen onto your outdoor plants. You might inadvertently damage them. Let it melt off on its own.
DO start to plan your garden for the new year. Order seeds and bulbs during the winter so you’ll be ready to plant in the spring. Need some help? Come to Super Seed Weekend on January 27 and 28 to talk to experts, attend a workshop, and find seeds and bulbs for your garden.
