Foliar fertilization good for flowering woody plants

Question: We have a crape myrtle tree in our southwest back yard. It gets plenty of water, and I fertilized it last month with some Miracle Grow flowering fertilizer.

Question: I read a small article online that you wrote about fruitless olive trees. We just had two new 36-inch box fruitless olive trees planted in our front yard. We noticed about a dozen green olives growing at the top areas of the trees.
