Crabapple Tree Care and Trimming
ArborScape is dedicated to help guide you to produce high quality, healthy crabapples. A flowering crabapple tree in your yard provides bright-colored fruit, which will attract birds. A sterile crab-hybrid will not bear fruit, making it a good choice close to sidewalks. Crabapples are hardy trees, but are prone to common diseases such as apple scab and fire blight.
Don’t eat the fruit of a tree you don’t know the history of. A crabapple – or any fruit tree – may be treated with chemicals that can poison the fruit for a season or more!
We recommend trimming crabapples during the dormant season (January and February) because of the high incidence of fire blight in the Denver area. Trimming during dormancy ensures that infected branches don’t release the bacterial agent into the air to find another host tree (typically rose, pear, or another crabapple nearby). Improper pruning, especially in fall, can strip away too many dormant buds – which may lessen foliage the next year.
