I planted some Lantana's and Pentas in my front garden and the Pentas's like really wilty. They aren't brown but very wilty. I live in Houston and it's been really hot but they are supposed to do well in the heat. I put down some organic fertilizer, and some plant food when I planted them. I watered them twice a day for the first 3 days and once a day for the next 2. What am I doing wrong? How much fertilizer and plant food is appropriate and how much water is appropriate?
Pentas is adapted to hot conditions, but could require frequent watering until the plants get established in their new location. Until the roots grow out of the old rootball, they have to get all their moisture from the soil that was in the pot. That means that you may need to water them daily for a while. On the other hand, too much water can drown the roots and cause wilting. Check the soil in the original root ball by touching it to see if it feels dry before you water again.
