March Garden Calendar
- Stop crabgrass before it starts by applying Ferti-lome All-Season II Crabgrass and Weed Preventer to cool-season lawns from March to early-April. Do not use a crabgrass preventer if you are planning to overseed.
- Spray dandelions, henbit, and chickweed in lawns with Ferti-lome Weed Free Zone.
- Clean perennial beds.
- Cut back ornamental grasses.
- In late-February or early-March prune Tea, Floribunda, and Grandiflora roses to 12”-18”, leaving the 5-6 best canes.
- When creating planting beds, mix Cotton Burr Compost with the existing soil. Compost breaks down clay soils, creates better drainage, and provide nutrients for new plantings. For individual plantings: mix Cotton Burr Compost with the soil that you are putting back around the root ball, at a rate of 1/4 compost to 3/4 soil.
- Start planting potatoes in mid-March. Cut seed potatoes into sections that are from 1-2 ounces and have at least one eye. Let the potato sections sit at room temperature for a few days before planting to prevent rotting. Plant 3-4 inches deep and 3 feet apart.
- Plant broccoli, cauliflower, and cabbage mid to late-March.
- Plant strawberries mid-March to April. Everbearing varieties produce longer while June varieties bearing produce more fruit but for a shorter season.
- Plant asparagus and rhubarb from mid-March to mid-April.
Trees and Shrub
- March is a great time to plant trees.
- To prevent borers on trees, use Ferti-lome Tree and Shrub Systemic Drench. It protects against borer for up to one year. Do not use on trees with edible fruit.
- Fertilize trees and shrubs with Ferti-lome Tree and Shrub Food in March or April.
