My Flamboyance Bougainvillea

Question

The leaves have wilted and browned and blow away. It went through a beautiful growth spurt two months ago after I was advised to add potash to the soil. Growth has stopped and my plant is looking down and out with no new life and no new white leaves only green ones. I have added more potash, a week ago, to no avail. We have a full north facing large courtyard and I have placed a climbing frame into the pot.

Answer 1

There are alot of things that could do this. Try giving it some balanced fertilizer (potash is mostly for potassium) and then treat the plant with neem oil. Neem oil will kill any fungus or pests that may be affecting the plant.
