Gardening Calendar for March

• Any root crops such as horseradish, parsnips, jerusualem artichokes, or carrots still in the ground from last year should be harvested before new green top growth appears.
• Cultivate weeds and remove the old, dead stalks of last year’s growth from the asparagus bed before the new spears emerge.
• To control iris borer, clean up and destroy the old foliage before new growth begins.
• Fertilize bulbs with a “bulb booster” formulation broadcast over the planting beds. Hose off any granules that stick to the foliage.
• Loosen winter mulches from perennials cautiously. Recover plants at night if frost returns. Clean up beds by removing all weeds and dead foliage at this time.
• Dormant mail order plants should be unwrapped immediately. Keep the roots from drying out, store in a cool protected spot, and plant as soon as conditions allow.
• Trees, shrubs, and perennials may be planted as soon as they become available at local nurseries.
• Gradually remove mulch from strawberries as the weather begins to warm.
• Mow lawns low to remove old growth before new growth begins.
