December Gardening Tips
HOUSEPLANTS
- On cold nights, move houseplants back from icy windows to prevent chilling injury.
- Over-wintering geraniums like bright light and cool temperatures. Keep soils on the dry side.
- Be sure newly purchased indoor plants are well protected for the trip home. Exposure to icy temperatures for even a few moments may cause injury.
- Water houseplants with tepid water. Cold tap water may shock plants.
- Holiday Poinsettia basics:
– Sun for at least half the day.
– Keep away from drafts, registers and radiators.
– Night temperatures in 50’s or low 60’s, days at 70 degrees.
– The soil should dry only slightly between thorough waterings.
Discard the drainage.
– Be sure to punch holes in decorative foil wraps to prevent soggy
soil conditions.
ORNAMENTALS
- Be sure the root zones of azaleas and rhododendrons are thoroughly mulched. Any organic material will do, but mulches made from oak leaves, shredded oak bark, or pine needles are preferred.
- Living Christmas tree basics: – dig the planting hole before the ground freezes. – mulch and cover the backfill soil and the planting hole to keep them dry and unfrozen. – don’t allow the tree’s roots to become dry. – spray with an anti-transpirant to reduce needle moisture loss. – store the tree outdoors in a cool, shady, windless area until the last minute. Mulch the roots to prevent cold injury. – set the tree up in your coolest room. – don’t keep the tree indoors for more than one week. Plant outdoors promptly.
- Hairspray works well to keep seed heads and dried flowers intact on wreaths and arrangements.
- Hollies may be trimmed now and the prunings used in holiday decorations.
- Only female holly trees bear the colorful berries. There must be a male tree growing nearby for pollination, if fruits are desired.
- Christmas trees hold needles longer if you make a clean, fresh cut at the base and always keep the trunk standing in water.
MISCELLANEOUS
- If you feed rabbits corn or alfalfa, they may leave fruit tree bark unharmed.
- Clean and oil all garden hand tools before storing for winter.
- All power equipment should be winterized before storage. Change the oil and lubricate moving parts. Either drain fuel systems or mix a gas stabilizing additive into the tank.
- Apply mulches to bulbs, perennials and other small plants once the ground freezes.
