November Garden Checklist
Things gardeners need to be considering for November.
Use this checklist to keep your garden healthy:
- Sometime after a hard freeze, cleanup your perennials by cutting back dead stalks
leaving 2 to 3 inch stalks and replenish the beds’ mulch. Remove old mulch in areas
where you had a severe disease problem or an insect infestation. Diseases and insects
can certainly overwinter in the old mulch.
- The easiest method to have more perennials from one plant, is division. Dividing perennials
is not difficult and can be done as the plant begins to decline this fall. A general
rule, plants that bloom in the spring, should be divided in the fall, with fall bloomers
divided in the spring. Summer performers can be done either season, but many choose
fall for a stronger plant next season. As the plants enter dormancy, the plant will
spend its energy establishing roots, and not foliage, thus giving you a stronger plant
next growing season. Lift the plants that need division, and divide them using a sharp
knife or spade, being careful to have a crown for each division.
- You can still plant garlic if you haven’t already. Garlic will grow roots through
the winter and foliage will appear in February or March. Harvest next summer as tops
begin to yellow. You can plant the culinary garlic you find in the grocery store.
- Fall is a good time to plant shrubs and trees in the landscape. Check out our tree care and planting tips .
- If you have been needing to move some established plants around in the landscape,
fall is the time to do so. Transplant deciduous plants after the leaves have dropped
and evergreen plants can be transplanted after the first hard freeze.
- It’s time to replenish compost heaps with the ample supply of leaves. Remember to
add some nitrogen to your layers of leaves for faster decomposition. You can use animal
manure or commercial fertilizer for your nitrogen source. If you don’t have good directions
on composting, call or come by your local County Extension office and we will be glad to give you a composting fact sheet with easy to follow directions.
- When planting pansies, and other winter annuals, be sure to use a fertilizer high
in phosphorous. Superphosphate will work. This will stimulate root development which
is needed to survive a cold winter. Pansies planted several weeks ago could use one
more shot of nitrogen before winter sets in.
- Spring flowering bulbs need to be planted by early December. Later planted bulbs run
the risk of not getting enough chilling hours to bloom properly especially if we have
a mild winter. As a general rule, bulbs should be planted three times deeper than
the diameter of the bulb.

- It’s not unusual to start seeing some spring flowering bulbs foliage starting to appear in the fall or early winter. Whatever you do, don’t cut off the foliage or you won’t have a flower next spring. Each bulb only contains one set of leaves, flowers and roots, and damaging these can damage your bulb. Simply ignore them, lightly mulch and wait for a bloom next spring.
- Don’t prune roses now. Fall pruning will encourage winter die back. Mulch roses up
past graft union for winter protection.
- Recycle disease-free annual potted plants and potting medium by adding them to the
compost pile or directly into the garden. Be sure to break up root balls from the
- Clean up emptied pots with a 10 percent bleach solution to get rid of any plant pathogens.
Read about how to sanitize your garden.
- Winterize your irrigation system by following recommended procedures with your particular
system. Remove hoses from outside nozzles to prevent freezing, but keep your hose
handy for winter watering in those dry protected spots. Winterize ornamental ponds
if needed and birdbaths if needed. Clay pots need to be put in dry storage, particularly
those which are not sealed.
- A soil test of all garden plots is recommended at least every 3 years. This is a great time to
get a soil analysis. You can make soil improvements this winter before spring planting
- Some people have noticed fallen twigs from pecan and hickory trees. These twigs are
no more than a half inch through and appear to have been cut off. This is damage done
by an insect called twig-girdler. This beetle lays its eggs on the twig and cuts it off. This damage is more spectacular
than damaging to the tree. The only control recommended is to pick up the twigs and
then destroy them thus destroying their eggs.
- Apply the last nitrogen (N) application to your tall fescue lawn sometime in late November. Apply 1-2 lbs. per 1,000 sq. ft. of actual N. This would be 3-6 lbs./1,000 sq. ft. of 34-0-0. If you have been fertilizing well, use the lower rate of N.
