November Gardening Guidelines
The cool, crisp days of fall are finally here,
bringing pleasant outdoor gardening weather. The change from daylight savings
reminds us that the first frosts and freezes of the year are not far away, and that more
changes are in store. There is plenty of gardening opportunities in November, but don't
let the days slip by before those important chores are done.
Bring in tender houseplant that have enjoyed being outdoors during the summer, and
give them a sunny location where you can keep up the humidity. Check for bugs
before bringing them in. A forceful blast of water will remove most unwanted guests.
Cut back on fertilizer, and water your plants after the soil slightly dries. Do not allow
water to collect in saucers, or you will end up rotting the roots at the bottom of the pot.
Plants are difficult to protect, even with covers, during windy, freezing nights because
the wind dissipates stored heat. On the other hand, covers offer several degrees of
protection if the freezing event is the result of a still, cold, cloudless night following a
sunny day and the temperature doesn't fall too far below 32 degrees.
If rain is elusive in the following weeks, irrigate as the soil becomes dry.
Drought-stressed plants are more easily injured by freezing temperatures. This is
particularly true of evergreen plants. Also, moist soil stores more of the sun's energy
and for a longer time than does dry soil. This energy is released as heat after the sun
sets, and provides a degree or two of moderation.
Harvest all warm-season vegetables before a hard freeze ends production.
If you have favorite tender plants you'd like to include in your garden next year, then
carefully dig them out of the flower bed, plant them in a well-drained potting mix, and
keep in a bright, humid room. They may look terrible during the winter, but if they
survive, you can replant them in the garden as soon as the soil begins to warm.
Or, take cuttings and root them in a well-drained potting mix.
Other bedding plants to chose from now include snapdragons, calendula, ornamental
kale/cabbage, and pinks or dianthus.
Some spring wildflowers, can still be sown from seed in early November, including
bluebonnets, Drummond phlox, rudbeckia and coreopis. Sow into a bare, prepared
soil, very lightly cover and water immediately to initiate germination.
Don't forget the interest plants with berries can add to the landscape. Pyracantha, all
kinds of hollies, nandina and beautyberry are just a few of the choices available for
bright, winter interest. This time of the year is actually a great time to plant all kinds of
trees and shrubs.
Trees are already beginning to change into their fall coloration. If you have been
considering a tree for your landscape, and would like one that has brilliant fall color,
make several visits to your favorite nurseries and check the tree inventories. Seedling
trees may vary in their ability to turn colors - one shumard red oak may regularly have
great fall color while another may never be anything but brown every fall. By selecting a
tree with good color in the fall, you'll have the assurance it will be able to put on a good
show in future autumns.
Don't forget tulip and hyacinth bulbs in the refrigerator. They can be planted anytime
this month if they have received 60 or more days of chilling. It's not too late to plant
daffodils, either.
Camellias will soon be coming into bloom. First the sasanqua and later the popular
camellia japonica. Select new varieties for a winter planting while in flower. Consider
time of bloom when selecting camellias. Sasanqua camellias, while not having as big
and showy flowers as japonicas, bloom earlier, usually escaping late freezes that can
blight open camellia japonica blooms.
Check existing camellias for scale underneath the leaves and treat with horticultural oil
or insecticide if found.
Don't get in a hurry to prune woody plants. Late December through February is usually
the best time to prune them - even later into March for crapemyrtles.
Late fall and early winter is an ideal time to adjust highly acidic lawn and garden
soils. Most grasses, except centipede, and most vegetable garden plants prefer a
slightly acidic to neutral soil pH. Many locations in East Texas have soils which are
strongly acidic which limits the potential of plant growth. The only way to know
for certain whether your lawn or garden needs an application of agricultural lime,
and how much is needed, is to have the soil tested for pH. Most soils, however, do
not require yearly applications. Test to be sure.
Once leaf drop begins in earnest, do not let wet leaves stay on the lawn. Wet leaves
block beneficial sunlight and keep grass wet, increasing the chances of disease. Mow
the lawn regularly to shred leaves into the turf, or rake them and add them to your
compost pile. Leaves and grass clippings combined make some of the best ingredients
for building a hot compost.
Build a compost pile (or 2 or 3) to deal with those leaves. It is not necessary to do all
the turning and other things you often read about to get those leaves to decompose.
They will eventually rot and turn into rich soil amendment. It will just take longer. But if
you are basically lazy or not in a hurry, then pile up the leaves in an out of the way
spot, and forget about them.
On the other hand, if you are industrious, or would like a source of excellent
organic matter to add to your beds in a few months, shred the leaves, and add roughly
equal parts nitrogen-rich material, like grass clippings, to the leaves. Moisten the
contents as you make the pile, which should be at least 3x3x3 feet. Turn it after each
time the pile heats up.
As caladiums fade, dig up the tubers while you can still find them. Store them in a dry,
cool place. Use dry sawdust or peat moss to help keep the tubers from rotting.
With colder weather approaching, birds will appreciate our help in supplying food,
water and shelter. Make sure feeding stations are located so you can see the action,
yet the birds are not threatened by neighborhood cats.
