December Gardening Calendar
December is, as it is everywhere, a festive season in the Southern Great Lakes Region. It is a busy time for all: Shopping, decorating, and entertaining all take top billing this month. Fall changes officially to winter this month, but with the winter holidays, one hardly notices the official passage into winter.
Generally, our region has already experienced a good snowstorm or two by the official turn of the season. Some years, however, autumn lingers long into the month. By now, planting chores and winter prep are completed with the garden and yard. Many of the leftover chores are hold-overs from last month’s list. Yet, there are a few other things we can continue to do in the home, yard, and garden this month:
1. Purchase some Christmas Cactus, Kalanchoes, Cyclamens, and Poinsettias to make your home more festive. Be sure to remove any foil wraps on the containers. These can hold water in the pots, which might cause the plants to rot from excess moisture. Make sure these plants are well wrapped before leaving the store for the trip home.
2. Buy some amaryllis bulbs to grow on the windowsill. Depending upon variety, some staking might be required.
3. Houseplants can suffer from the lack of humidity. Growing plants in pebble filled trays and saucers can help maintain humidity around plants. Set your plants on the pebbles, and fill the saucer or tray with water to just the top of the pebbles.
4. If your roses aren’t protected, do so early in the month. Spray anti-dessicant on any exposed canes when the daytime temps are above 40. Mound soil, mulch, and leaves around the base of the plants to about 18 to 24 inches above the base of the bushes. this is especially true of hybrid teas, floribundas, and roses that have been growing in the yard less than two years, and any other marginally hardy rose. Some of the bush roses, such as the Explorers, Rugosas, Mordens, and Buck’s roses can overwinter successfully in our zones 5a to 6a region without protection. Again, if any variety was newly planted this past season or has been in the ground less than two years, protection would still be a good idea.
5. Continue watering outside when the weather is above freezing, if there has not been sufficient precipitation and the ground has not frozen. Drain hoses after removing them from the faucets to prevent damage to hoses and plumbing.
6. Try to take a daily walking tour of your yard, as the weather permits. Observe frost patterns in your yard in early morning. See where frost lingers, where frost does not hit, and write this down in your diary or journal. Often a surprise plant or two will be blooming in a protected spot. These are indicators of microclimates, and you can use this information when planning on where to site plants.
7. Check the coldframe for any problems. Make sure plants are overwintering without the problems of standing water, field mice, disease, insects, or excessive cold. Prop it open on days that are sunny and above freezing to prevent excessive warming of your plants.
8. Continue to keep birdfeeders filled. Birds offer a lot of winter interest, and by making your property attractive to birds, these helpmates might decide that your place would make a good home next year. Many birds migrate to the region from further north, but many birds make our region their year-around home.
9. Take cuttings of holly and evergreen boughs indoors for Christmas decorating. Also fill outdoor window boxes with Christmas greens and decorative bows.
10. Keep fresh-cut Christmas trees in a cool, not freezing location. After bringing a tree home, cut 1 to 2″ from the base and plunge it into a bucket of tepid water with preservative added to prevent the cut end from sealing over. Don’t let the water run dry! When bringing a tree indoors for decorating, allow it to rest in the stand with water in it for several hours to allow the tree to “relax” its branches as it becomes acclimated to indoor warmth. Then decorate.
11. Gardening catalogs should start arriving this month. Start a list of items that you want to purchase for planting next spring. This is also a good time to take out any pictures you have taken of your gardens during the past growing season. You can see what you might need to add to your gardens and yard.
12. Potted Christmas trees should be placed in a cool, not freezing, area until brought indoors for decorating. These trees should not be brought in for extended periods. A day or two before Christmas and a few days after will not harm them. If kept too long indoors, they will break dormancy. After Christmas, take the tree out to the area where you prepared the planting site earlier (see October’s calendar), and plant it. Water well and mulch.
13. Continue to keep bird feeders full. Word will get around, and you will be amazed at how many visitors will come to call during the winter months if you provide a steady supply of suet and seed!
14. Remove any stray leaves that may have blown in around your plants. If they are not shredded, they can mat down around your plants and smother them or promote rotting.
15. Continue to apply mulch to your flowerbeds as the ground freezes to prevent freeze/thaw heave and premature breaking of dormancy.
16. Have a gardener on your gift list? A gift certificate to a nursery or garden center would be appreciated. You can also “gift” him or her with a gift certificate to a gardening-related mail order source. Another good idea would be a gift subscritption to a gardening magazine.
18. Most of all, have a Blessed Holiday Season, one and all!
