Prepare Bulb Beds
If you expect to plant many spring-flowering bulbs this fall, take time now to prepare the planting area. Select a sunny location with fertile, well-drained soil. Remove the sod and loosen the soil down deep (about 10 or 12 inches down for tulips and daffodils) so the bulbs' roots will be able to grow through it easily.
Plant Last Veggies
Last call for fall-planted veggies. You can still seed radishes, lettuce, spinach, and chard to pick and eat later this fall. You might also eke out just one last crop of peas before the snow flies.
Shelter Tropical Plants
Temperatures below 50 degrees can harm some tropicals, so be prepared to protect them on chilly nights, even while allowing them to savor the last sunny days of the season outdoors. Bring them indoors overnight, cover with an overturned cardboard box, or toss on a spun fiber frost blanket from the garden center as temporary protection.
Fall is for Planting
Early fall (September to early October) is a great time to start lawns and plant trees, shrubs, and perennials. To allow ample time for the plants to become well rooted before the truly cold weather sets in, stop planting about two months before the ground usually freezes.
Keep On Harvesting
Keep harvesting those zucchinis and tomatoes and all the other bounty of the lingering fall garden. Enjoy it fresh, preserve it, share it with friends, or compost it, but whatever you do, pick it clean. Don't allow produce to deteriorate and rot in the vegetable garden because this can encourage pests and diseases.
