Fungi on Indian Hawthorne

Question

If I cut off all the infected parts of the plant there will only be the bare base of the plant (no foliage), will the plant grow back?

Answer 1

Although Indian hawthorn can survive severe pruning, I do not recommend cutting the entire plant to the ground. You can replace the plant entirely, or you may wish to cut the plant back to 6 or 8 inches, wait for new growth to appear, and then eventually remove the rest of the diseased branches.
