what to do in your garden in December

Citrus and vegetable plants love liquid seaweed—spray vegetable plants

weekly and citrus trees monthly for added nutrients and disease


New plant growth slows down and some pests go dormant in the cooler

months, but spider mites and thrips can still be a problem. Keep checking

for pests regularly and apply horticultural oil or soap sprays as needed.

December is a good time to plant trees and shrubs—but postpone major

pruning, especially of trees and shrubs that are cold sensitive, to avoid

encouraging new growth before a cold snap.

Have your cold-protection plan in place and watch weather reports. Be

ready to cover tender plants with sheets and blankets if a freeze or frost

warning is in place. Watering plants the day before a cold snap is also

beneficial. Bring in orchids if temperatures drop below 40°F. More details

Be sure to let your citrus ripen on the tree before picking; unlike some

other fruit, citrus does not improve in flavor after being picked. If your citrus

was planted less than two years ago, encourage the tree’s growth by

removing most of the fruit as soon as it forms.
