Seasonal Gardening Tips

Continue watering evergreens until the ground freezes. Soils must not be dry when winter arrives.

Now is the ideal time to plant trees and shrubs. Before digging the hole, prepare the site by loosening the soil well beyond the drip line of each plant. Plant trees and shrubs at the depth they grew in the nursery and not deeper. Remove all wires, ropes and non-biodegradable materials from roots before back filling. Apply a 2-3 inch mulch layer, but stay several inches away from the trunk. Keep the soil moist, not wet, to the depth of the roots.

Plant tulips now as well as any other spring-flowering bulbs you have not yet planted.

Fall tilling the vegetable garden exposes many insect pests to winter cold, reducing their numbers in next year's garden.

To prevent injury to turf grasses, keep leaves raked up off of the lawn.

Clean house gutters of leaves and fallen debris before cold wet weather sets in.

Continue to inspect plants you brought  indoors closely for insect pests such as aphids, spider mites, scale, and whitefly.

Hold off applying your winter mulch to roses until after a hard frost (below 24 degrees F.).
