Though our temperatures are still surging now and then, shorter days and cooler nights mean that fall is on its way. Time spent in the garden is more comfortable for us AND our plants. After a summer spent watering and weeding, other landscape jobs are calling for attention.
September and October are great times to add perennials, trees, and shrubs. Pansies and mums take center stage, though scores of other plants add gorgeous color to our fall landscape. Consider plants for migrating pollinators. Ironweed, Goldenrod, Asters, and Sedums are among fall bloomers.

Move houseplants indoors when nighttime temperatures are the same inside and out. Use insecticidal soap or horticultural oil to address insect issues. Avoid repotting unless absolutely necessary. Most houseplants go dormant from November to March. Limit fertilization as well.
Harvest and store green tomatoes in paper bags to ripen. Keep at room temperature.
Lift tender bulbs like Cannas, Callas, Begonias, Dahlias, and Caladiums before a hard frost. Store in a cool, dry place and set out in spring after the last frost date.

Plant spring-flowering bulbs in October or November, as soil temperatures cool. Here is a guide to bulbs from the University of Maryland.
Fertilizing and seeding the lawn is best done in fall. Soil temperatures remain warm, so seed germinates faster. Most of our grasses are cool-weather turf-type fescues. Check our seminar schedule for our fall lawn clinic and other Fall Events.
Empty pottery containers not in use. Remove saucers from beneath the pots. Store upside down in sheds or garages.
Drain hoses, clean and sharpen gardening tools.
