March Gardening Calendar
The ground is warming up and there’s a springlike feeling in the air so we’ve rounded up a gardening to-do list for you.
Lawn and Landscape Care
- Crabgrass herbicides should be applied when Forsythia blooms
- Cautiously control cool season weeds in turf. Before applying chemicals check to make sure the lawn isn’t greening up.
Trees and Shrubs
- Trees and shrubs are coming out of dormancy. Now is the time to fertilize them. Follow the soil test results recommendations. In the absence of a soil test apply 10 pounds of 10-10-10 fertilizer per 1,000 square feet of bed area.
- Be on the lookout for insects coming out of dormancy. Look closely for crawlers of scale insects and spider mites. Treat the plants if you see these insects.
- If an overgrown shrub needs to be rejuvenated, make sure it is one that will come back from such heavy pruning, then cut it back this month.
Fruits and Vegetables
- Fruit trees and blueberries can be pruned up until the flowers begin to open on the plants. Muscadine grapevines can be pruned before the leaves are fully opened.
- Spray fruit trees with dormant oil to eliminate scale insects that may have overwintered on the bark of the plant.
- When apple and pear trees are blooming they can be sprayed with streptomycin to prevent the bacterial disease fireblight.
- If you enjoy starting tomatoes, peppers and other summer crops from seed indoors, now is the time to get them started.
- Asparagus beds can be fertilized before spear growth begins.
- Broccoli, cabbage, and cauliflower can be set out in the garden around mid-March
- Beets, carrots, Chinese cabbage, kale, kohlrabi, lettuce, Swiss chard, turnips and potatoes can be planted anytime this month.
Ornamental Flowers and plants
- Start summer annuals by seed indoors.
- Plant flowers to attract pollinators
- Perennials like daylily and Shasta daisy can be divided at this time if the ground is dry enough,
- Remove spent flowers from pansies and spring bulbs.
- Fertilize emerging flower bulbs.
- Mosquito season is upon us. Empty any objects that hold water.
- Clean out gutters so water will drain, preventing mosquito habitat.
- Clean drainage ditches and convince neighbors to do the same. Moving water is not good habitat for mosquitoes, standing water is.
