Growth Stages

1

Establishment

First 1-2 years

Young tree with developing root system and initial branch structure; minimal fruiting

Water regularly to establish roots; stake if needed for wind protection; light pruning to shape structure; avoid heavy fruit load

2

Early Fruiting

Years 2-4

Tree begins producing berries; branch structure becoming established; canopy filling in

Continue regular watering; thin competing branches; apply balanced fertilizer in spring; monitor for pests

3

Peak Production

Years 5-20+

Mature tree with full canopy; producing abundant berries from early summer through fall; multiple fruiting cycles

Water during dry periods, especially during fruiting; prune selectively to maintain shape and air circulation; fertilize annually in spring; harvest frequently to encourage continued flowering

4

Maintenance

Long-term

Established tree maintaining consistent annual production; possible signs of aging (hollow wood, reduced vigor)

Rejuvenation pruning if needed; address disease/pest issues promptly; maintain regular watering schedule; thin interior branches for light penetration

Harvest Tips

Berries ripen progressively from early summer (June) through fall (September-October); pick when fully dark and soft, typically every few days as new berries mature. Berries do not all ripen at once—the 'everbearing' trait means continuous flowering and fruiting. Harvest in early morning or evening when cooler. Spread cloth under tree and gently shake branches for easier collection. Best flavor when fully ripe and fully dark.

Fun Facts

  • 🌱 Illinois Everbearing is named for its exceptional ability to produce berries continuously throughout the summer and fall, rather than in one short flush like most mulberry varieties—some trees produce fruit from June through October.
  • 🌱 Mulberry leaves were historically the primary food for silkworms in sericulture (silk production), making the tree economically important in Asia for centuries.
  • 🌱 The tree is extremely hardy and vigorous, often thriving in poor urban soils where other fruit trees struggle, making it ideal for challenging growing conditions.
