- Nursery stock, including trees, shrubs, & vines.
- 4-inch or larger containers of ground cover will establish better.
- Pansies, pinks, snapdragons, ornament kale and cabbage
- Daffodils-choose early and smaller-flowering types to repeat bloom year after year.
- Spring perennials, i.e. iris, daisies, daylilies, coneflowers, violets, oxalis, hardy amaryllis and ferns become crowded. Dig and divide early in the month.
- If transplanting established trees and shrubs wait until first hard freeze when they are completely dormant.

- Remove old flower stalks, dried leaves and seedpods from perennial beds.
- Keep mowing until frost and use clippings and leaves as mulch in flower beds or in compost.
- Remove as much as 40-50% of top growth from bougainvilleas and tropical hibiscus before bringing them in for the winter. Find a bright warm location for them.
- Remove damaged or dead branches before trees lose all their leaves.
- Checkout Proper Pruning Techniques for more information.
- 20-20-20 water-soluble for new annual and perennial plantings
- Cool season grasses i.e. rye and fescue with high-nitrogen or all-nitrogen food will give growth before winter.
- If tropical plants are in greenhouse feed lightly with 20-20-20 fertilizer twice a month.
- Adding 1 cup of all-nitrogen fertilizer per cubic yard, keeping it moist, and covering with black plastic will boost your compost faster .
- Dandelions, clover, henbit and other non-grassy winter weeds-treat with broadleaf weedkiller (containing 2,4-d) by the end of the month. Apply weedkiller as directed on container. More is NOT better!
- Spray unwanted grass, weeds in new flower beds before cold weather causes them to go dormant.
- To eliminate the source of re-inoculation for spring, remove mummified fruit and diseased leaves.
- When moving plants inside, check for unwanted insects hiding in the pots. When temperatures begin to fall into the 40’s, its time to bring plants in.
- For tender outdoor plants, use frost cloths during freezing weather.
Nurseries start clearing out for Christmas stock, so be on the lookout for bargain prices for plants taking up space for the Christmas merchandise.
