Getting rid of the problem plant material from this year is a good start to a better-looking landscape next year. You can thank the resistant survival structures of disease-causing organisms for this extra work. Many plant pathogens are protected from adverse weather conditions thanks to these suits of armor. Tucked in plant tissue, they are ready to do damage in the spring. It refers to pulling, digging, pruning, raking, bagging and maybe burning.
Tools needed for the job include tough gardening gloves, pruners, a rake and a tiller.
A good starting point is the fungi that found your perennials. Some fungi cause spots on leaves. Diseased leaves often turn yellow or brown and drop from the plant or they may wither on the stems. Peony leaf blotch is a common and easily recognized leaf disease. The large purplish leaf spots can be spotted from a distance.
