Horticultural Tips
November Tips*
q Use your lawn mower or a leaf shredder to shred leaves and then use them as mulch on your beds or add to your compost pile. No reason to discard Mother Nature's free soil amendment!!
q Plant spring-flowering bulbs now.
q Remove dead annuals and tops of perennials that do not provide winter interest. Do not compost any plant material that is infected with pests or diseases.
q Prune broken or damaged deciduous trees and shrubs this month but wait until late November or December to do any formative pruning.
q Prune broadleaf evergreens to shape.
q Wait until early spring to fertilize trees and shrubs.
q Continue planting trees and shrubs this month, as long as the ground is not frozen or too wet.
q Do not plant Southern Magnolias or Cherry Laurels until March.
q Continue to monitor soil moisture around newly planted shrubs & trees. If we receive less than 1" of rain per week, provide supplemental water. Consider attaching a rain barrel to your downspout to collect rainwater for later watering of plants when rain is scarce.
q Add new mulch to any beds that need it. Mulch will help retain moisture, protect roots from freezing and help prevent perennials from being "heaved" out of the ground during freezing temperatures. Keep all mulch away from necks of plants.
q Roses can be pruned by 1/3 to avoid breaking in winter winds. Rake up any fallen leaves to prevent spread of pests and diseases, such as blackspot. Mulch well, but keep away from crown.
q Remember to winterize your irrigation system for the winter.
