Growth Stages

1

Seedling

2-3 months

Tiny, 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

2

Juvenile Growth

1-2 years

Small 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

3

Establishment

1-2 years

Shrub 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

4

Flowering & Fruiting

Ongoing, primarily spring-summer; 2-3 months per cycle

Small 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

5

Maturity

Indefinite; plant lives 10+ years

Well-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
