| Black knot (fungus) |
 |
Large black galls on branches. |
See black knot under Plum for more information. |

Decline  |
Gradual loss of vigor. Foliage may be sparse, and leaves may be smaller than normal, turn yellow and drop. |
Two common causes: poor soil aeration and freeze injury to bark. Plant in well-aerated soil. Also see freeze injury below. |

Freeze injury |
Twigs may not survive the winter. If injury is to the bark of the trunk, the tree may decline slowly or bloom, then suddenly wilt and die. |
Many types of ornamental cherries are not reliable in Missouri's climate. Plant the hardiest varieties. Plant in a protected location. |
