Anything that you can do to provide good drainage will help chrysanthemums to survive. Some root rot diseases will spread by splashing water, so try to have your mums away from puddles if you can. Building up the soil in the area where you’d like to plant can definitely help. Or, you might plant them in containers or raised beds, to get them off any saturated ground. Improving soil drainage by mixing in lots of organic matter might help as well. Also provide good air circulation (such as not too close to other plants, plant in a sunny spot), to help dry leaves during the day and deter disease. Hope this helps!
