Culture Notes
This European beech can tolerate a wide variety of soil conditions from sand to clay as long as the drainage is adequate. Once established it only needs occasional watering during prolonged dry periods. It is a handsome specimen and should be provided enough space to fully develop. It rarely needs pruning to maintain its naturally graceful and majestic form and the thin, delicate bark can be easily injured. For these reasons, consult an experienced pruner or arborist before attempting to prune. Woolly aphids can be a minor problem, but sprays are not required since they do not jeopardize the tree’s vigor or health. Avoid planting near driveways or patios where the sticky “honeydew” from the aphids can create sticky surfaces.
