| my pentas are turning brown at the tips of leaves and then there is a lot of dead brown leaves within the plants as they grow larger. What is the problem?How often do I have to cut off dead flowers? |
| I can't diagnose the problem without actually seeing it but it sounds like a fungal disease. I'd prune the plants back to remove the browning foliage. Pentas are Tolerant of a wide-range of soil types, but they prefer fertile, well-drained soils. They will grow in full sun to part shade but flower best in full sunshine. Plants can be clipped as a hedge but flower production will suffer. They are best left unclipped so flowers are free to develop on new growth. You don't need to regularly deadhead the spent flowers but you can to make the plants look more attractive. |
