• Roses often put on some of their best displays in the November-December period of cooler weather. Encourage them at this time with plenty of water during dry spells and good cultivation, finishing with a topping of fresh mulch to save moisture and ameliorate temperature changes.

• Place orders for seeds this month so you will have them available when you are ready to plant. By ordering early, you will be more certain of getting the varieties you want. In addition to ordering seeds that you are already familiar with, try a few new kinds each year to broaden your garden contents.

• Don’t get in a hurry to prune woody plants. Late December through February is usually the best time to prune them.

• Reduce the fertilization of indoor plants from late October to mid-March. An exception would be plants in an atrium or a well lighted window.

• Drain gasoline from power tools and run the engine until fuel in the carburetor is used up.

• Drain and store garden hoses and watering equipment in a readily accessible location. The lawn and plants may need water during a prolonged dry spell.

• November through February is a good time to plant trees and shrubs. In the Panhandle, planting is often delayed until February or early March.

• Continue to set out cool-season bedding plants, such as pansies, violas, stock, snapdragons, and dianthus.

• Prepare beds and individual holes for rose planting in January and February. Use composted manure, pine bark, and similar materials mixed with existing soil.

• Use good pruning practices when selecting Christmas greenery from landscape plants. Don’t destroy the natural form and beauty of the plant.

• Protect your lawn from excessive winter damage by providing irrigation during dry periods.

• Plant spring-flowering bulbs if you haven’t already done so. Be sure to refrigerate tulips and hyacinths for 6-8 weeks prior to planting.

• Prolong the life of holiday-season gift plants by providing proper care. Check to see if the pot wrap has plugged up the bottom drainage. Don’t overwater. Keep out of drafts from heating vents and opening doorways. Fertilizer is seldom needed the first few months.

• Take advantage of good weather to prepare garden beds for spring planting. Work in any needed organic matter, and have beds ready to plant when needed.

• Don’t forget tulip and hyacinth bulbs in the refrigerator. They can be planted any time in December if they have received 60 or more days of chilling.

• Want to start cuttings of your favorite Christmas cactus? As soon as it has finished blooming, select a cutting with 4 or 5 joints, break or cut it off, and insert the basal end into a pot of moderately moist soil. Place it on a windowsill or other brightly lit area. The cuttings should be rooted within 3 to 4 weeks.

• Don’t spare the pruning shears when transplanting bare-rooted woody plants. Cut the tops back at least one-third to one-half, to compensate for the roots lost when digging the plant.

• Take advantage of bad weather and holiday time to study seed and nursery catalogues as well as good gardening books.

• Berrying plants, such as holly and yaupon, may be pruned now while they can be enjoyed as cut material inside the house.
