1、 Cut off the remaining flowers

After the peony has completely withered, its remaining flowers need to be trimmed immediately. These failed flowers have no ornamental value. Leaving them on the plant will only waste nutrients, so they need to be cut off immediately. When cutting, cut off the base of the flower stalk together with its flower stalk. You can't just cut flowers, otherwise the remaining flower stalks may rot

2、 Cut off diseased leaves

Because its flowering period is summer, diseases are easy to occur during this period. So after it blooms, check whether there are diseased branches or leaves on the plant. If yes, it needs to be cut off immediately, and after cutting, spray some fungicides on it to prevent bacteria from infecting other branches and leaves

3、 Bad pruning

It needs a lot of nutrients to blossom, which may also lead to some non flowering branches becoming dry and yellow because they can't get enough nutrients. If the maintenance environment is not very good, this symptom will be more obvious. When you see these dried branches or yellow leaves, you also need to cut them off together
