I have approximately 50 hibiscus planted around my house. All were planted at the same time about two years ago. All are quite healthy and filled out except the 4-5 plants in the accompanying picture. I have cut them back, along with all the others, fertilized them, and, about 6 weeks ago, replanted them raising them some 3-4", thinking that possibly they were getting too much water from the irrigation system. I put several inches of small rocks in the bottom of the hole and included several shovels full of a moisture control planting soil. The plants are quite alive, and show some blooms. They also get exactly the same sun/shade, etc, as the other plants. However, unlike all the other plants these refuse to fill out. Any comments/suggestions would be greatly appreciated.
