Care

Light

Needed for the best blossom display.

Water

Water well while establishing; avoid waterlogged ground.

Soil

Fertile, well-drained soil; dislikes heavy, poorly drained clay.

Pruning

Prune only in summer, never in winter — winter cuts risk silver leaf disease and bacterial canker entering the wound.

Feeding

A general feed in early spring for a young tree or one growing in grass; an established specimen in a border needs nothing. Keep feed and mulch clear of the trunk, where they encourage rot at the graft union.

Propagation

Not a home job: ornamental cherries are grafted onto selected rootstocks, which control the eventual size and habit, and nothing you raise from a cutting or a stone will resemble the tree you have.

Month by month

Months change with the climate: in southern Italy tomatoes go out two months earlier than in England.
