What to Do in December

For more details on the following, call your local Extension office or visit the University of Florida’s publication website: http://edis.ifas.ufl.edu 

Plant and fertilize annuals. (See January)

Reduce irrigation frequency as weather cools. (See November)

Plant containerized roses. (See November)

Select and care for "potted" poinsettias. For a long-lasting display, select plants with tight, green buds in the center of the red bracts. Yellow pollen should not be shedding. Place plant in a cool, sunny, draft-free location.

Rake up fallen leaves. Use leaves as mulch or compost leaves by layering them with a little lime and small amounts of fertilizer or manure.

Trouble-shoot houseplant problems. Brown leaf tips of margins--too much fertilizer or too dry. Thin new growth or yellowing older growth means too little light. Wilting and yellowing mean too much water or poor drainage.

Protect tender plants during cold weather. Protect plants with covers that extend to the ground. This will trap heat radiating from the soil.

Mow and fertilize ryegrass. Frequent fertilization is necessary to keep ryegrass dark green and growing. Weekly mowing may be required.

Plant cold-hardy landscape plants. Cold hardy plants establish easily during winter months.

Transplant trees and shrubs. Plants that are dug and moved need not be pruned. The plant will naturally shed what it can't support. Keep the plant well watered.
