Crepe Myrtle

Why doesn't my dwarf Crepe Myrtle bloom?  It is six years old and it only bloomed twice, but not the last two years.

Hey Reb.

Sometimes when we plant full sun trees in partial shade, they still get enough sun at first to bloom. Often, as a landscape matures and surrounding trees and shrubs get larger then the increased shade will trigger a tree to not bloom as a survival tactic.

Is your tree getting full sun or is it perhaps dealing with drought conditions or planted in a sandy soil?

The tree is in full sun, we have no drought and the soil is Georgia clay.

Hi Reb.

Have you been pruning the tree?  Buds form off new growth, so pruning may be preventing blooms.

Is this tree in your lawn that you are fertilizing?  Lawn fertilizer is primarily nitrogen, with little potassium and little to no phosphorus.  The feeder roots for your tree will lie in a ring between 4 and 7 feet away from the trunk.  If this area gets the residue from lawn food, then it will encourage the tree to grow foliage, but not so much to bloom. 

You could use a Ross root feeder to fertilize the tree.  This would be a good solution if there has not been much lawn fertilizer used near the tree.  If there has been, then maybe something like Morbloom would work out better.

Thanks, Chris.  I will try Ross root feeder as the tree has never been pruned and we don't fertilize the lawn.
