Seedling
2-3 monthsTiny, delicate seedlings with small oval leaves emerge slowly from seed
Keep soil consistently moist but not waterlogged; provide bright, indirect light; be very patient as germination is slow and irregular
Juvenile Growth
1-2 yearsSmall shrub develops multiple stems and leathery, dark green leaves with prominent veining
Maintain moderate moisture; begin light pruning to encourage branching; ensure excellent drainage to prevent root rot
Establishment
1-2 yearsShrub reaches 3-4 feet in height with increasingly dense foliage; first flowers may appear
Reduce watering frequency; mulch lightly with organic material; prune to maintain shape; transition to drought tolerance training
Flowering & Fruiting
Ongoing, primarily spring-summer; 2-3 months per cycleSmall white or pale pink flowers appear; followed by small berries that ripen from red to dark purple
Maintain consistent but not excessive moisture during fruit development; avoid heavy nitrogen fertilizer which promotes foliage over fruit; provide light afternoon shade in hottest climates
Maturity
Indefinite; plant lives 10+ yearsWell-established shrub 4-6 feet tall producing reliable berry crops
Prune after fruiting to maintain shape and remove dead wood; minimal fertilizer needed; well-adapted to low water in natural habitat
