Seasonal Gardening Tips

As day lengths increase, plants begin new growth. Repot rootbound plants, moving them to containers 2 inches larger in diameter than their current pot. Check for insect activity and apply controls as needed. Leggy plants may be pruned now.

To control iris borer, clean up and destroy the old foliage before new growth begins.

Loosen winter mulches from perennials cautiously. Re-cover plants at night if frost returns. Clean up beds by removing all weeds and dead foliage at this time.

Mow lawns low to remove old growth before new growth begins.

Cultivate weeds and remove the old, dead stalks of last year's growth from the asparagus bed before the new spears emerge.

Fertilize the garden as the soil is being prepared for planting. Unless directed otherwise by a soil test, 1 to 2 pounds of 12-12-12 or an equivalent fertilizer per 100 square feet is usually sufficient.

Gradually remove mulch from strawberries as the weather begins to warm.

Continue pruning grapes. Bleeding causes no injury to the vines. Tie vines to the trellis before the buds swell to prevent bud injury and crop loss.

Set up nesting boxes for bluebirds.
