Typical gardening activities taper off at this time of year.
Even though we have received a plentiful 50+ inches
of rain from Hurricane Harvey about 3 months ago, we
have received very little rain since that time. So while
our annual rainfall to date is quite impressive, the rainfall
that started on Sunday is much needed as our area
was entering into a pre-drought stage.
The month of December ushers in a state of dormancy
for many landscape trees and shrubs. What is
good for plants is oftentimes good for the gardener. The
month of December offers something for every gardener
to do and even enjoy. Review the following gardening
checklist for December for gardening reminders and

Till Garden Beds: Unlike our gardening friends above
the Mason-Dixon Line, our soils don’t freeze solid so
we can work the garden soil and prepare beds for next
spring’s planting activities. When working garden soil,
whether for planting flowers and shrubs or a vegetable
garden, never till or work the soil when it is wet, especially
soil with high clay content. Tilling wet soil tends
to degrade soil structure, forming large clods that may
take a long time to break down. Soil works up best
when it is slightly moist, yet crumbles readily after being
hand-pressed into a ball.
POINSETTIAS: Christmas poinsettias are widely
available now. Keep the potting soil evenly moist, never
let the soil dry out or become soggy for long periods.
Poinsettias are often purchased with decorative foil
wraps that do not allow water drainage. Be sure to take
your poinsettia out of these types of decorative pots
before watering. Water your poinsettia whenever the
surface of the soil appears dry and the plant feels light
when you lift it.
The best way to water a poinsettia is to place it in a
sink and add water until it begins to drip out of the bottom
of the pot. Keep the plant in the sink until all excess
water has drained out of the pot and then place it back
into its ornamental container.
If your poinsettia is sitting in a container with a saucer
underneath, pour out any extra water the saucer captures
PRUNING: Don’t be in a hurry to prune woody plants.
Very late December through early February is usually
the best time to perform most winter pruning.
