What To do in Your Garden in December

December is my favorite month of the year! My calendar fills up quickly with holiday events and family gatherings. Be sure to set aside time to do some much-needed pruning and planting. Your landscape and garden will thank you!
Protect
- Protect moveable plants from sudden changes in temperature by bringing them indoors.
- Protect tender plants by placing layers of mulch or pine straw to a depth of 6-8 inches.
- Water plants well if there is warning before a frost. Otherwise water as the plants begin to thaw.
Plant
- Toward the end of the month plant tulips and hyacinths that have been in the fridge for 6 weeks.
- Plant many types of bare-root trees: fruit, nut, or citrus.
- Plant dormant shrubs: azalea, camellia, nandina, wax ligustrium, Indian hawthorne, pyracantha, mock orange, hydrangea, flowering quince, and spirea.
- Herbs for a sunny window: tarragon, chives, oregano, marjoram, and rosemary.
Prune
- Prune fruit trees and shade trees to remove damaged wood.
- Cut off tops of brown perennials, leave roots in the soil.
- Do not prune spring flowering shrubs.
- Ferns will come back from the ground, cut back brown fronds.
- Cut mistletoe out of trees.
Indoor Plants
- Houseplants to consider: African violets, amaryllis, begonia, bromeliads, Christmas cacti, dieffenbachia, ferns, philodendron, schefflera, and weeping fig.
- Feed houseplants twice during the winter months.
Miscellaneous
- To maintain a live Christmas tree in good condition, mix in a 2-liter bottle: 8 oz non-diet soda, 2 oz vinegar, 1 oz mouthwash. Fill the bottle with water. Keep base of tree in this solution. After Christmas have your tree turned into mulch. Some Christmas decorations are poisonous to people and pets: Keep boxwood, holly, mistletoe, and Jerusalem cherry high up and out of reach.
In Bloom
- Sweet pea, sasanquas, poinsettia, camellia, osmanthus, narcissus, and amaryllis.
