Sour cherries prefer consistent moisture, especially during fruit development. Water deeply when the top 5-7 cm of soil feels dry. Avoid waterlogged conditions, as this can lead to root rot.

Reduce watering slightly in late summer and fall to help the plant harden off for winter.

Prune sour cherries in late winter or early spring while dormant. Remove any dead, damaged, or crossing branches. Aim for an open canopy to improve air circulation and light penetration.

This also helps maintain the tree's shape and encourages fruit production on older wood.

Sour cherries are typically propagated by budding or grafting onto rootstock. Seed propagation is possible but often results in offspring that do not reliably exhibit the parent plant's characteristics.

Rooting cuttings is generally difficult for this species.

Repotting is generally not applicable to mature sour cherry trees grown outdoors.

Young trees or those grown in containers may require repotting every 2-3 years into a slightly larger container as their root system develops. Use well-draining potting mix.
