Question: 807-3412
Can we grow Crepe Myrtle here in central Illinois like the ones in North Carolina? Ed, Springfield.

Mort's Answer:
I would certainly try. Springfield is now in zone 6 and close to 5b. Lagerstroemia indica comes in alba, rubra and purpurea: white,red and purple respectively. With the trend toward warmer climates , more plants will be able to flourish in your area. Hedge your bet and plant them on the south side of a structure. Then, you can bet on a hedge. They can be pruned after the first year to the ground. They are also be trimmed into a bush or tree. They are easily regenerated from cuttings like the Rose of Sharon.

My three Crepe myrtle trees have not done much. They are in their third year. They barely are three feet tall at most. Can I add fertilizer? Susan, Oakdale, WV

Mort's Answer:
Crepe can be treated like a shrub the first two or three years and be cut to the ground to strengthen the stems. Definitely add some 5-10-10 granular to the soil. Next year you can trim the branches as a tree.

My six Crepe Mrytle have not produced many flowers yet. The plants are five years old with a lot of vibrant foliage. Any suggestions? Bosrah, CT

Mort's Answer:
Lagerstroemia indica can be cut down to the ground the first two years to strengthen the roots. That is not the root of your problem. You need to apply some 5-10-10 fertilizer about two feet from the stem. Make a radius of five holes that go down 18 inches and fill them with the fertilizer. Many folks will grow the Crepe as a shrub. Others will trim the lower branches to form a tree with a single trunk, very much like a Rose of Sharon. It is not uncommon for them to wait a few years to bloom

Question: 1170-3914
I have a crop of second generation seeds from Crepe Mrytlettes. The parents are about five feet tall. New cuttings are about five inches in clay pots. Can I put them outdoors? Should I keep them through the winter? Bob, Uncasville, CT

Mort's Answer:
You could put them outdoors and plant them with the pots now. Put them in a protected area and cover them with straw after they have defoliated. You should remove the pots in the spring and place them in a permanent spot. A fail safe method would mean keeping them as houseplants until spring time. You will have to cool them down indoors and barely keep them alive. This means giving them very little water through the winter.

Question: 1273-2715
My six foot Crepe Myrtle did not produce an flowers this year. I did give it some 5-10-10 last year. There are a lot of new shots at the bottom. Should I remove them? Ed, Bosnia, CT

Mort's Answer:
Lagerstroemia indica grows to 20 feet as a tree or shrub. Each winter all the new shoots should be cut to the ground. You should leave no more than three to five trunks to grow. This will enable the roots to support blooms as well as foliage. Usually Crape (sometimes spelled Crepe) Myrtle is not hardy zone 6 north. This past winter in the northeast did not allow enough heat in the spring for a lot of flower buds to set. You could add some aged manure now but you will need to prune this into a small tree to get best results.

Question: 300-5201
Our Crepe Myrtle has what appears to be white fungus growing on the leaves. It has affected the flowering. How can we get rid of it? Huff, Douglasville, GA

Mort's Answer:
If there is a white mass at the joints, the Lagerstroemia indica has mealybug. Malathion should correct this. If the white powder is at the middle and end of the leaves, your Crepe or Crape myrtle has indeed a fungus. Captan, ferbam or benlate are all excellent fungicides. A home orchard spray will correct both the mealybug and the fungus. Follow directions on the labels.

Question: 1007-3613
My three year old Crepe Myrtle did not produce any flowers this year. I bring it in each winter. It is about four feet tall. Should I cut it back? Rose Marie, Griswold, CT

Mort's Answer:
Crepe can be cut to the ground the first two years to strengthen the roots. Cut it in half before you take it indoors this year. Give it two tablespoons of 5-10-10 fertilizer. This will give the soil more phosphorus to help produce more flower buds in the spring. Lagerstroemia indica will bloom all summer when it matures. It can be trimmed to be a bush or tree.
