Gaspé Serviceberry

Cusick's Serviceberry should be watered thoroughly and regularly. During the active growing season (spring and summer), it is recommended to water the plants every 7 to 10 days, making sure to apply enough water to saturate the root zone. During periods of drought, increase the frequency of watering and decrease the intervals between waterings. In the winter, abstain from regular watering, but be sure to check up on the plants during dry spells and water as necessary.

Cusick’s Serviceberry (Amelanchier cusickii) needs 6-8 hours of direct sunlight in order to thrive. This deciduous plant prefers to receive full sun during the morning and a partial shade during the late afternoon to avoid any harsh direct sunlight. During cooler and shorter days, this species may need a few more hours of sun. In general, Cusick’s Serviceberry should be placed in full sun to partial shade.

Pruning Cusick's Serviceberry (Amelanchier cusickii) should be done in late spring, just after flowering is complete. Pruning should be light; the branches should be thinned to open up the canopy and remove any dead, diseased, or weak limbs. Selective pruning is best so that 1-third of the branches are removed to increase air circulation. For more productive fruit crops, the branches should be thinned further to remove old and unproductive wood. It is not necessary but can be beneficial to remove thin branches that may be crossing or growing towards the inside of the plant. Routine pruning is not necessary, but it is best to do a light trim at the end of the season to remove any excess or deadwood.
