Planting & Tree Care

SOIL

Accepting of a wide variety of soils, but best with deep, well drained fertile soil.

PLANTING SITE

A sunny and sheltered position is best, protected from Spring frosts. Plant 4-5m apart from other trees.

CLIMATE

European plums are suitable in most areas of the country, including the coldest regions. Japanese plums need less Winter chill and need protection from late Spring frosts so can also be grown in warmer, Northern regions. 

WATERING

Water frequently while young then during long dry periods and when the fruit is developing.

GENERAL CARE

Never prune Plums from March through to July, due to disease risks. Prune during dry periods from Spring to Summer to control vigour and to shape. 

PESTS & DISEASES

Diseases like Silver leaf and Bacterial blast can affect Plums, but with careful cultural practices they normally need minimal care. 

FRUIT

Varieties range in ripening time from mid Summer to early Autumn.

POLLINATION

See pollination chart. Plant at least one pollinating variety to ensure good fruit production.

TREE SIZE

Height up to 5-6m.

RECOMMENDED PRUNING SYSTEM

Central leader or Vase shape.
