March gardening checklist: Protect trees and prep for spring blooms
March brings a mix of tasks for gardeners as winter fades. From protecting trees to preparing spring blooms, timely care can prevent damage and encourage growth. Some jobs, like pruning oaks or reviving houseplants, need attention before the month ends to avoid bigger problems later.
Heavy snow from March storms can weigh down evergreen branches and trees with horizontal limbs. Gently brushing off the load prevents branches from snapping or bending permanently. Meanwhile, early spring bulbs will start pushing through the soil this month, signalling the start of the growing season.
Lawns recovering from winter stress may show vole damage as grass begins to grow. Light raking helps repair the turf, but aggressive raking should wait until the lawn is fully active. For indoor plants, dust on leaves blocks light and slows growth. Wiping them with a soft, damp cloth keeps them healthy—just avoid spreading pests or diseases between plants.
Oak wilt remains a serious threat, particularly in red oaks, which can die within weeks of infection. The disease spreads when sap beetles, drawn to fresh pruning wounds, carry fungal spores from April to June. To reduce risk, oaks should be pruned by the end of March, before beetles become active. The fungus has spread widely across central and southern US states, especially in Texas and Oklahoma, though management efforts have slowed its advance in some areas.
For dormant flowering plants like overwintered geraniums, it's time to move them from dark storage to brighter spots. Any plants needing repotting should be refreshed, watered, and placed under grow lights by month's end to encourage strong spring growth.
Completing these tasks now sets gardens up for a healthier season. Pruning oaks early avoids oak wilt, while careful cleaning and repotting help indoor plants thrive. As temperatures rise, attention to lawns and emerging bulbs ensures a smoother transition into spring.
