Care Guide

Watering

Water deeply once a week during active growth and fruit development.

Fertilization

Apply a balanced organic layer of compost at the base.. Mulberries generally do not require heavy fertilization once established.

Banana Peel and Coffee Ground Mix:Bury chopped banana peels and a small amount of used coffee grounds in the soil around the drip line. This provides a slow release of potassium for fruiting and nitrogen for leaf growth. Cover well with soil to prevent mold and odors.
Pruning
  • Prune during winter dormancy (December to February) to prevent excessive sap bleeding;
  • Remove dead, diseased, or crossing branches to maintain an open canopy;
  • Thin out crowded interior branches to improve air circulation and light penetration;
  • Avoid heavy pruning in spring, as the tree will bleed sap heavily from cuts.

Garden Uses & Culture

Culture: Introduced to Europe in the Middle Ages and later to the Americas by King James I in the 17th century in an ambitious attempt to establish a British silk industry. It has since become a naturalized, sometimes weedy, shade tree across Western landscapes.

Usage: Cultivated for its edible sweet fruits, used in jams and pies. Historically and commercially vital as the primary food source for silkworms. The wood is also used for turning and fence posts.
