The summer gardening season is quickly turning over to fall gardening tasks. Whether you’ve planted fall crops or are harvesting the last of your summer vegetables, there are a handful of tasks to complete this month.


Plant hardy perennial bulbs

If you want to plant bulbs that aren’t hardy, like begonias or gladiolus, dig them up and store them over winter. Plant them in the spring and they’ll bloom in the summer.

Fall ornamentals

Certain ornamental plants thrive in September, including chrysanthemums, flowering kale and flowering cabbage.

Ohio State University CFAES says that ornamental kale and cabbage can be planted in the fall or very early spring.

Tend to your fall garden

Your fall crops should reach maturity before this month’s first potential frost. If needed, cover tender plants with burlap, baskets, boxes, blankets or buckets to protect them from cold temperature damage, according to Virginia Cooperative Extension.

Save seed

Only save seed from cultivars that you want to grow again next year. Keep in mind that you can’t save seed from hybrid varieties.

Online columnist Ivory Harlow explains how to save seed, including when to save seed from specific plants to drying and storage methods. According to Harlow, it’s easiest to save self-pollinating peas, beans and tomatoes, but other varieties such as squash, melon and cucumber can be hand-pollinated.

Clean up your garden

Clean up remaining plants once everything has been harvested. Add healthy plant debris to your compost pile. Grass clippings not treated with herbicides and leaves can be added to your compost bin, too. Spread a thick layer of compost over your garden this fall. If you don’t have a compost pile, till the plant debris into the garden’s soil.

Diseased plants should be disposed of separately so the disease doesn’t spread. Don’t leave plant debris in your garden. Insects will lay eggs, opening the possibility of an infestation come spring when you’re ready to plant.

Other ways to clean up your garden include amending soil, weeding and removing spent annual flowers.


Ohio State University Extension recommends fertilizing your lawn during fall (August or September) and late fall (October, November or December). Before you fertilize, make sure you’ve had your soil tested so you know which nutrients are needed. Soil testing improves texture, fertility and pH levels.
