are enthusiastic gardeners, and passionate about history and historic preservation.
We are fortunate to have them as volunteers here.

November Garden Tips

Debbie Foster
Horticulture Director

Cooler weather makes fall a great time to plant trees and shrubs. Planting now gives them plenty of time to get established and develop roots before the heat and drought of next summer. Proper planting techniques are essential to plant survival. Plants that are planted too deep become stunted, decline and even die. Planting trees and shrubs too deep is a very common cause of plant death.

Planting too deep suffocates the roots. Tree and shrub roots must have oxygen to grow and survive.  If a Improper Mulchingplant is planted too deep, it causes a sudden change in the availability of oxygen.Covering the roots with too much soil is like putting a pillow over a person’s face. There’s simply not enough oxygen to survive. This can also happen if plants are in waterlogged soils that don’t drain well or if they are being over watered. The roots slowly suffocate and die. Normal trees have a gentle trunk flair or buttress at their Base. The trunk flair (top of the root ball) should be planted slightly above grade to allow room for a 2 to 4” layer of mulch. Mulch should never be more than 4” deep and it should never come in direct contact with the trunk.

Another common mistake when planting is leaving the root ball intact after removing it from the container.  Roots left in the shape of the container can girdle the plants over time. A girdling root is one that circles the base of a tree at or just below the surface. Expansion of the root and the trunk squeezes them against each other, interfering with the transport of water, nutrients, and sugars.

Girdling RootsDevelopment of girdling roots is normally the result of unfavorable conditions which prevent roots from growing out in a normal spreading manner. A good example is a container-grown plant, where the roots are often forced to grow in circles. If these roots are not pruned at the time of planting, this growth pattern can cause girdling roots.

Root pruning is an absolute must for any container-grown tree or shrub at the time of planting. Three to five slashes are made vertically down the sides of the root ball and about 1” into the root ball. One or two slashes into the bottom of the root ball or removing the bottom inch or two from the bottom of the root ball will also help eliminate circling roots. Whatever the method used, circling roots must be loosened and redirected. If more than 50% of a tree’s trunk is girdled, it will decline and die.

Getting plants to bloom indoors can sometimes be a challenge.  Thanksgiving cactus and Christmas cactus are popular, fall and winter blooming houseplants. When grown under normal day light conditions, Thanksgiving cacti normally blooms near Thanksgiving approximately one month before Christmas cacti bloom. Another member of the group sold as holiday cacti is the Easter cactus, which Christmas Cactusflowers primarily in the spring and sporadically throughout the year with pink or red flowers.

During the fall, the Thanksgiving and Christmas cacti depend on long nights and cooler temperatures to set their flower buds. These plants should receive 14 or more hours of uninterrupted darkness for at least 6 weeks to initiate and encourage setting buds. Poinsettias are another plant that require long nights to initiate blooming. If you saved your poinsettia from last year and you want it to re-bloom, provide 14 hours of darkness for 9 to 11 weeks. Be sure to place them back in a sunny location during the day.

Orchids on the other hand do not require long nights to bloom. Orchids need a 10 to 15 degree temperature change between day and night to initiate blooming. In the fall, placing them outdoors or in a garage (55 to 60 degrees) during the day and bringing them indoors (70+ degrees) at night will help provide the necessary temperature change. Just remember not to put them in direct sun or they will burn.

Forcing DaffodilsTo force daffodil and other bulbs to bloom indoors in the winter, pot up bulbs between September and December. Use a potting mix that drains well and plant the bulbs so the top of the bulb will be even with the top of the pot. After planting, water the soil thoroughly and place the pots in a refrigerator at 35 to 48 degrees. The soil should be kept moist but not wet during the cooling period. Store the bulbs for at least 13 weeks (15 is preferred). After the required cooling period, the pots can be brought in the house and placed in a sunny window for 3 to 4 weeks. Once the flowers begin to open, take the plants out of direct sunlight so the flowers will last longer.

If the deer are eating your pansies, come out to Lockerly Arboretum to learn how to cope with these night time flower eating critters.  We are experimenting with different techniques for deer control.  For more information, or to set up a time for you to come out and talk with me, please call me at 478.452.2112 or email

GCSU students help launch Art in the Arboretum

September 29, 2015

Lockerly is partnering with professors and students in the GCSU Art Department for our first Art in the Arboretum during the month of October. Students and art classes will be visiting the Arboretum and Rose Hill and create artwork that reflects the beauty of this setting. Students working in all kinds of mediums are invited to submit their work to the Arboretum by October 29th.

Early next year we will host an exhibit of GCSU student artwork in Rose Hill. Following the exhibit here, we will work with local businesses so the artwork can be displayed throughout the community. If your business would like to display some of the work that is submitted by GCSU students, contact Lockerly’s Executive Director, Katherine Cummings, at or call 478.452.2112.
