Growth Stages

Establishment (Young tree)

1-2 years

Single trunk with lateral branching developing; foliage green and tender; minimal flowering

Stake if necessary for wind protection. Water regularly but allow soil to dry between waterings. Apply organic mulch. Remove weak or crossing branches. Protect from strong winds.

Vegetative Growth

1-2 years

Rapid height and canopy expansion; increased branching; dark green glossy foliage; no flowering yet

Continue regular watering. Apply balanced fertilizer (10-10-10) quarterly. Prune to shape the canopy and remove dead wood. Train central leader or multi-stem form as desired.

Flowering

3-8 weeks

Small white or pale pink fragrant flowers appear in clusters; flowers emerge primarily in spring to early summer

Reduce nitrogen fertilizer to encourage flowering; apply phosphorus-potassium rich fertilizer. Avoid heavy pruning during flowering. Ensure adequate water availability.

Fruit Development & Maturation

8-12 weeks

Small green berries develop, gradually enlarging and changing color from green to pink to deep purple-black; fruits reach 0.5-1 inch diameter

Maintain consistent watering. Apply potassium-rich fertilizer to enhance fruit quality and sweetness. Thin excessive fruit if desired for larger individual fruits. Watch for pest infestations.

Harvest & Post-Harvest

2-4 weeks per season

Fully ripe fruits are dark purple to black, soft, and easily detach from branches; very perishable with short shelf life

Harvest ripe fruits by hand or by spreading cloth beneath tree and gently shaking branches. Use fruits fresh immediately or process quickly. Prune lightly after harvest to maintain shape.
