Gardening Know How Questions & Answers - https://questions.gardeningknowhow.comHi, I am based in Cambridge, UK. I purchased some bedding chrysanthemum plants from a garden centre and planted them in my garden in mid-July. Since planting, I have seen the plants produce new buds which then turned brown and did not open. This was accompanied by leaves developing dark/black patches. Following heavy rainfall in mid-August, the plants produced a lot of new growth and new buds. However, I noticed that the leaves around some of these buds are curling upwards and am concerned that the buds themselves could again fail to open. I have attached pictures showing a bud that turned brown and did not open, the dark patches on a leaf and the leaves curling around the new buds. Apologies in advance – there are bits of mown grass on some of the leaves, but I hope the images are sufficiently clear. Would you be able to identify the problems and what could be done to remedy them? Many thanks in advance. Best wishes, James Ng

This article should help. I would cut off as much of the dark buds, leaves as possible.
