I purchased three white hibiscus at Home Depot. I used Mircle Grow Potting Soil and planted all three in a new pot. One by one, the plants are dying. They turn brown and have unopened buds on each of them. I removed the last one and placed in a pot by itself to try and keep it alive. I would take the two dead ones back but I didn't keep track of my receipt. What could be wrong? Thanks. |
