Magnolias are well known plants to gardeners and many are familiar with the foliage and flowers of these plants. If you are looking for another earlier bloomer, you may want to consider adding a specimen selection to your landscape, the Star magnolia (Magnolia stellata).
Although not native to the United States, star magnolia is a slower growing multi stemmed deciduous shrub reaching about 15 feet in height over time. The best feature are the bright whitish pink star-shaped blooms appearing in late winter before leaves emerge. The flowers offer gardeners a peek of the spring to come and remind us that our Gulf Coast winters are not that long. 
Plants do best in soil with some organic amendments and mulch over the root systems. A planting area that receives a little afternoon shade is ideal but established plants will adapt to sunnier locations when irrigation is provided during drier weather. Only occasional pruning is required to remove crossing branches or those that grow out of bounds. Prune after flowering if needed.

Though the calendar says December, the weather in Northwest Florida fluctuates between winter and spring temperatures. The nice days are wonderful opportunities to accomplish many of those outside landscape chores in preparation for spring. But, it is also a good time to start planning for next month’s colder temperatures. Since we don’t experience frozen soil, winter is the best time to transplant hardy trees and shrubs. Deciduous trees establish root systems more quickly while dormant; versus installing them in the spring with all their tender new leaves. Here are a few suggestions for tasks that can be performed this month:
- Plant shade trees, fruit trees, and evergreen shrubs.
- Plant pre-chilled daffodil and narcissus bulbs (late December/early January).
- Do major re-shaping of shade trees, if needed, during the winter dormancy.
- Water live Christmas trees as needed and water holiday plants such as poinsettias as needed.
- Check houseplants for insect pests such as scale, mealy bugs, fungus gnats, whitefly and spider mites.
- Continue to mulch leaves from the lawn. Shred excess leaves and add to planting beds or compost pile.
- Replenish finished compost and mulch in planting beds, preferably before the first freeze.
- Switch sprinkler systems to ‘Manual’ mode for the balance of winter.
- Water thoroughly before a hard freeze to reduce plants’ chances of damage.
- Water lawn and all other plants once every three weeks or so, if supplemental rainfall is less than one inch in a three week period.
- Fertilize pansies and other winter annuals as needed.
- Protect tender plants from hard freezes.
- Be sure to clean, sharpen and repair all your garden and lawn tools. Now is also the best time to clean and have your power mower, edger and trimmer serviced.
- Be sure the mower blade is sharpened and balanced as well.
- Provide food and water to the area’s wintering birds.

A visit to a nursery and homeowners will see so many new selections of plants for the landscape. Some of these plants are new plant developments and may include plants we could not previously grow in Florida’s heat and humidity. One new plant series is the Southgate® Rhododendrons.
Anyone from more northern areas of the South is very familiar with the rhododendrons that offer showy spring blooms. Those particular rhododendrons just don’t make it in our Florida climate.
The Southgate® series from Louisiana were developed to be more tolerant of our weather conditions. Homeowners must still consider plant placement very carefully since these plants have some specific requirements even in Florida. Plants will do best in shade or filtered shade, especially in the afternoon. They do like an acid soil amended with compost and areas that are well drained. Homeowners will need to supply water during the growing season to maintain a uniform soil moisture.

Consider trying one of these newer rhodendrons if your landscape has a suitable spot and you will definitely enjoy a bright spot of color come spring.
Special Note: If you have animals or children be cautious since all plant parts are toxic if ingested.

Myrica cerifera Southern Waxmyrtle, Bayberry is a large shrub to small tree that is now native to much of Florida and much of the Southeastern United States. It was introduced to Europeans in the 1700s and is considered native by many botanical authorities. Sources disagree to the validity of its native status. It is usually found as an understory plant in lightly forested areas, swamps, brackish areas, as well as around old home sites.
It was planted widely in the 18th,19th and early 20th century as a plant for medicinal and industrial purposes. Four pounds of its berries will yield one pound of wax for candle making. When processed, this wax was also used in surgeon’s soap, shaving lather, and sealing wax. Fermented leaves were used to produce a substance which was said to treat fever, stomach aches, and headaches.
Southern Waxmyrtle can reach up to 25 feet but is best maintained as a 10-20 foot multi-trunked shrub or small tree. It can also be trained as a smaller hedge and several dwarf form exist. Landscapes are enhanced by the shrubs’ olive green foliage, leaf aroma, open, rounded form and waxy blue-green berries. Wildlife enjoy the berries as a food source as well. They can provide dappled shade for outdoor entertainment spaces or front entrances.

Another benefit of Waxmyrtle is that it can be used in tough-to-landscape roadside and coastal areas since it is both pollution and salt tolerant and will cease to require irrigation once it is established. ‘Pumila’ is a dwarf cultivar suitable to small spaces.
Waxmyrtle is susceptible to few pests and diseases but can occasionally be attacked by webworms, mites and caterpillars. These can be controlled by pruning out of infested areas, forceful applications of water or Bt (Bacillus thuringiensis for caterpillar). It is also occasionally susceptible to canker on old branches and Fusarium wilt in central and south Florida. It is also considered a weed in pasture situations.

There are a number of plants in my landscape that bring back fond memories – plants that I propagated.
Red Mulberry. Photo credit: Vern Williams, Indiana University, bugwood.org.
There’s a mulberry tree in my backyard that I rooted years ago. I took the cuttings from an old mulberry tree in my hometown. As a boy, I climbed the tree, got in trouble once for coming home with mulberry stains on my clothes. I liked the berries and still do. I have good childhood memories about the tree.
About twenty years ago I visited the property adjacent to my childhood home. The tree was still there. It was during mulberry season. I enjoyed a few mulberries. I took about eight or ten cuttings from the tree. About a year after my visit, the property sold. The new owner bulldozed the tree.
But because of the cuttings that I rooted, the tree still lives and not just in my memory. The trees produced by those cuttings are genetically the same as the parent tree. Essentially, they are clones. The one in my backyard produces mulberries each year.
You too can propagate memories. Not all plants can be propagated from cuttings but many can be. Sometimes trial and error is necessary to learn proper timing in taking cuttings. But most reliable references will provide the time of year to take cuttings based on the plant species.
Stem cuttings should be removed from the parent plant with a clean, sharp knife or pruner. Ideally your cutting should be 4-6 inches in length and not much thicker than a pencil in diameter.
Take the bottom two-thirds of leaves off on each cutting. The cuttings should be stuck upright in a propagation medium. I usually use a good quality potting mix and mix in a little course sand or perlite for better drainage. The cuttings should be inserted deep enough to hold them upright, usually ½ to 1 inch.
To help promote rooting of moderate to difficult to root plants, wound the cuttings by scraping the lower ½ to 1 inch of the stem with a clean, sharp knife. The scrape should remove the bark or “skin.” Then dip the cutting in a rooting hormone covering the scrape with the rooting powder prior to inserting the cutting into the rooting medium.
I usually use a four inch pot, gallon size pot or bedding plant flat with drainage holes as a rooting container. I may stick as many as ten stem cuttings in a gallon size pot. I place the container of cuttings in a shady location outdoors and keep it moist. The cuttings should produce roots in two to sixteen weeks, depending upon plant species and the environment.
After the cuttings have rooted, carefully remove them and individually plant each rooted cutting in its own four inch to one gallon size pot. Keep the potting medium moist but not soggy. After the roots adequately fill the pot, the plant should be strong enough to be planted in the ground.
As your rooted cuttings grow, hopefully they will provide fond memories.
