How to grow

Cultivation

Grow in moderately fertile soil in full sun. Cherries are best suited to fan-training so they can be netted against bird damage and protected from frosts. Further sweet cherry cultivation advice

Propagation

Propagate by chip budding or grafting on clonal rootstock for fruit

Suggested planting locations and garden types
  • Wall side borders
Pruning

Train fan-trained trees in spring. Prune established fans and carry out routine pruning on established cherry trees when harvesting the fruits in summer

Pests

Protect trees from birds that damage buds and eat the fruit. May suffer from aphids, caterpillars, leaf-mining moths and winter moth caterpillars

Diseases

May be affected by silver leaf and blossom wilt but shows some resistance to bacterial canker
