Seasonal Gardening Tips

Pinch azaleas and rhododendron blossoms as they fade. Double flowered azaleas need no pinching.

Don't remove spring bulb foliage prematurely or next year's flower production will decline.

Mid-month plant summer bulbs such as caladiums, dahlias, cannas and elephant ears.

Keep bluegrass cut at 1.5 to 2.5 inch height. Mow tall fescue at 2 to 3.5 inch height.

Place cutworm collars around young transplants. Collars are easily made from cardboard strips.

Begin planting sweet corn as soon as white oak leaves are as big as squirrel ears.

Control caterpillars on broccoli and cabbage plants by handpicking or use biological sprays such as B.t. 

Herbs planted in average soils need no extra fertilizer. Too much may reduce flavor and pungency at harvest.

Birds eat many insect pests. Attract them to your garden by providing good nesting habitats.
