Seasonal Gardening Calendar
January is typically the coldest winter month. Still, you can accomplish such garden tasks as sharpening your mower blade, building a nurse bed for new plants and shredding fallen leaves for mulch.
JANUARY Week 1
January Shopping List
Get ready for roses
Prepare beds for bare-root roses that will soon arrive in nurseries. Dig an area four feet wide and twelve inches deep for each plant, adding plenty of soil conditioner to the soil.
Tend to your poinsettias
Water poinsettias only as needed – when the top inch of the soil becomes dry to the touch. Keep them in bright light but cool temperatures. Do not fertilize until March.

Tune up the mower
Now is a great time to drain and replace the oil in your mower and to have the blade sharpened or to replace it completely.

Prune your trees
It is easy to see the limb structure of trees now. Tie ribbon around the ones you think should be removed then step back for another look before cutting them off.

If the ground is dry, till the soil in your vegetable garden. You’ll eliminate lots of insects, weeds and nematodes.

JANUARY Week 2
Small, leafless shrubs and trees can be transplanted easily now. Wait for a warm day when the ground is not frozen.
Cut back kudzu and bamboo
Chop unwanted kudzu, English ivy and bamboo to the ground. Follow with weedkiller on the leaves in April.

Prune pampas grass
Prune clumps of pampas grass down to 12 inches tall. Use a gloved hand to pull out dead stems in the clump.
Water pansies and ornamental kale after a hard freeze so they can re-hydrate their wilted leaves. Remember to regularly water window boxes and other outside plant containers.
Give houseplants a half turn every month so they don’t lean too much in one direction.
JANUARY Week 3
Spray for mites
Check indoor plants for insects like spider mites, scale, and mealybugs. Remember to spray insecticidal soap or indoor houseplant insecticide on the undersides of leaves to get good pest control.

Bring in amaryllis
Amaryllis flower stems and their faded blooms can be removed now. Treat it like a houseplant for the rest of the winter then plant outdoors in a sunny bed in May.
Prepare for cold weather
Use calcium chloride or potassium chloride instead of salt on icy sidewalks. Too much rock salt (sodium chloride) can burn nearby plant roots.
If temperatures drop below 20 degrees after a week-long warm spell, cover gardenias and camellias nightly with black plastic anchored to the ground on all sides.

Request seed catalogs
Write or call for your yearly supply of garden plant and seed catalogs. Buy an issue of a gardening magazine for addresses and phone numbers.
JANUARY Week 4
Plant pansies and daisies
Plant pansies and English daisies in a sunny bed when the weather is mild. Use plants in three inch or larger pots to make an immediate impact in your landscape.
Look out for poison ivy when working outdoors. Even the leafless vine and branches can cause a powerful skin reaction if touched.
Mist your houseplants
Watch for brown edges on houseplant foliage. Mist the leaves twice each day and move them from drafty areas.
Check your bulbs
Check on the tender bulbs (canna, caladium, dahlia) you stored indoors for the winter. If they are beginning to shrink, mist each one with warm water.
Prune your fruit trees
Prune apple and pear trees and grape vines.
