( Fig. 1 ) . During the process of repotting , prune decayed roots and provide proper soil drainage . In hosta , the wedge-shaped lesion is delimited by the veins ( Fig. 1 ) . After planting , prune all canes back to four to six above-ground buds ; the resulting low bud count encourages the development of vigorous new canes . For a nonbearing fruit tree , prune to develop a basic structural framework that will support future crops . Do not replant with another peony or other plant susceptible to Verticillium sp. Sclerotinia sclerotiorum can cause stem rot on peony as well as on many different herbaceous plants found in the garden . Susceptible flowers include asters , cockscomb , chrysanthemum , coreopsis ( core-e-OP-sis ) , cosmos , echinacea ( purple coneflower ) , dianthus , glads , marigolds and petunias . There is no need to add fertilizer to the hole or to the backfill soil . Diagnosis of Southern blight can be made by looking for the signs of the fungal growth [ Fig. 1 ] .
