Seasonal Gardening Calendar

December

Time to pick a Christmas tree. The fewer green needles that come off in your hand when pulled, the better the tree. To protect your bulbs foliage from the cold, spread some pine straws.

    Control chickweed

    Continue to spot-spray or dig out chickweed, violets and wild onions you find in your lawn.

    See Chickweed Control

    Rake the last of the leaves

    Rake the last of the fall leaves from your lawn. If you leave a pile of wet, matted leaves now you’ll have big dead spots next spring.

    Choose a Christmas tree…

    When choosing a cut Christmas tree, gently pull a branch through your fingers. Few, if any, green needles should come off in your hand.

    See Selecting a Christmas Tree

    Plan a fun family outing to cut your own Christmas tree! Tree farms supply saws, wagons and free wrapping for your soon-to-be-tinseled timber. For a list of farms, visit the Georgia Christmas Tree Growers Web site

    …or a houseplant

    Celebrate the beginning of Hanukkah, The Festival of Lights, by giving a houseplant – the gift that keeps on giving!

    Install bermuda sod

    Bermuda sod can be planted if it is available but be sure to water it regularly for the rest of winter to keep it from drying out.

    See Installing Sod in Winter

    Keep holiday plants cool

    Keep holiday plants in the coolest indoor spot possible. Otherwise the flowers and leaves will drop prematurely.

    See Poinsettia Care

    Potect your bulbs

    Sprinkle pine straw over bulb foliage that has emerged too soon. The green leaves won’t be hurt by the cold but the straw will help hide them.

    Bring your yard chemicals indoors

    Bring containers of liquid bug spray and weed killer indoors and store in a safe place. Freezing can cause chemicals to lose their potency.

    Prune evergreen shrubbery

    Prune your evergreen shrubbery and bring the cuttings indoors. Juniper, holly and magnolia foliage is quite decorative. Use holly and nandina berries for a red accent in table centerpieces.

    Water poinsettias

    Poinsettias do not need fertilizing now but they do need watering. Check the dryness of the soil daily to keep them looking their brilliant best.

    Prune your trees

    Prune short stubs and dead limbs from trees now that all the leaves are gone.

    see Pruning Trees

    Clean or propagate houseplants

    A good job for dreary winter days is to clean or propagate your houseplants. Both are easy to do.  

    see Cleaning and Propagating Houseplants

    Check on your ficus plants

    Ficus plants that lose leaves are reacting to insufficient light or a drafty site. Can you move yours to a better place in your house?

    see Ficus Care

    Check on your holiday plants too

    Poke holes in the foil wrapping on pots of holiday plants and set them in individual saucers. Otherwise accumulated water will cause root rot.

    Fill your bird feeder

    Bird feeders bring lots of colorful activity to a yard in cold weather. Most bird experts recommend black oil sunflower seed for general feeding. Thistle seed and suet cakes attract birds you might not have seen before.

    see Feeding Birds

    Bring a houseplant to the party

    Rather than a bottle of wine, bring a houseplant as a gift to holiday parties. Amaryllis, ornamental pepper, Christmas cactus or kalanchoe will be appreciated for weeks to come.

    see Christmas Cactus Care

    Pull mulch away from tree trunks

    Pull mulch at least six inches away from tree trunks. Many professional landscapers pile it high and don’t pull it back – setting a bad example for all of us.

    see How to Mulch Correctly

    Water new trees and shrubs

    Water trees and shrubs you planted this fall. Evergreen plants in particular need regular watering, even in cold weather. Apply 1 gallon per foot of height.

    see Planting Shrubs Correctly

    Winterize your mower

    Don’t leave your lawn mower out in the rain. Water can get in the gas tank and prevent starting next spring. It is best to drain the tank completely or run the mower until it is out of gas.

    You might need these

    Buy some African violets

    Purchase pots of paperwhite narcissus, African violet or gloxinia for your office and home to bring color and maybe a touch of perfume to the air.

    See African Violet Care

    Water your Christmas tree

    Forget the powders and potions! What a Christmas tree needs to stay fresh is a constant supply of water around its base.

    See Watering a Christmas Tree

    Plant woody vines

    Plant woody vines like Carolina jessamine, wisteria and cross vine now. Make sure to place them next to a sturdy arbor and loosely tie the young vine to it with twine.

    See Native Plants for Georgia

    Tend to your houseplants

    Houseplants don’t need many nutrients in the winter. Use houseplant fertilizer at half strength. Don’t water them unless the soil feels dry one inch deep.

    Tidy up your amaryllis

    Remove the faded blooms and bloom stalks from amaryllis but allow the leaves to remain. Water only when the soil feels dry.

    Scatter fireplace ashes over your lawn

    Fireplace ashes can be scattered over your lawn. They will provide a bit of phosphorus and potassium plus counteract soil acidity. Spread no more than ten lb. per 1000 square feet every six months.
