Harvest Tips
Berries ripen progressively from green to red to black over several weeks. Harvest when fully black and slightly soft to the touch (they will not ripen further after picking). Gently roll berries into a basket or cloth laid beneath branches—ripe fruit drops readily when ready. Peak harvest is typically early morning. Fruit can stain clothing and concrete, so plan accordingly. A single mature tree can produce 10-50 lbs per year depending on conditions.

- 🌱 Black Beauty is a relatively recent cultivar developed to maximize fruit size and sweetness while maintaining a compact, productive tree suitable for home gardens and containers.
- 🌱 Mulberry trees can live 50-100+ years and become extremely productive—some heritage trees continue producing abundantly after centuries.
- 🌱 The ripe berries are so soft and juicy they can be 'milked' by hand—gently rolling ripe fruit between fingers releases pure juice, which was a traditional treat for children.
