Tidy Up Flower Beds

While you're out planting spring-flowering bulbs, such as daffodils and tulips, clean up debris in the flower beds. Deadhead flowers one last time and remove annuals that have finished for the season. Compost the plant debris to eliminate insect eggs and disease pathogens, and next season you'll have fewer pests in your garden.

Cultivate Soil to Reduce Weeds

Make a routine of cultivating the top inch or so of soil in annual and vegetable gardens and around shrubs and trees. When you disturb the soil you bring overwintering insects and weed seeds to the surface. Birds foraging for food will get a snack, and you'll have less work next spring.

Sow Onions

You'll get larger onion bulbs that won't bolt in early spring if you sow seed or transplant seedlings now. Purchase the smaller onion sets for best performance. Bulblets should be only about half an inch wide. If they're larger, they may bolt in early spring. Plant larger ones to use as green onions through the winter since they will bolt and set seed instead of bulbing in spring.

Bring Houseplants Indoors

Time to bring houseplants in from their summer stay outdoors. Be sure to check them thoroughly for hitchhiking pests. This is also a good time to repot them in fresh potting mix. Toss the old mix out into the garden or onto the compost pile. Keep plants in a bright area indoors for a few weeks so they'll gradually get used to the darker, warmer, and drier indoor conditions.

Groom Perennials

Remove faded blooms of perennials like coreopsis, Shasta daisies, delphiniums, penstemons, and yarrow. Divide clumps that are too large or ones that haven't bloomed much this year. After replanting, sidedress with compost and water them well.
