Juvenile Growth

6-12 months

Small shrub develops narrow, linear leaves with sticky resinous coating; branching becomes apparent

Gradually reduce watering. Ensure excellent drainage. No fertilizer needed. Acclimate to full sun exposure

3

Establishment

12-24 months

Plant develops deeper root system and woody structure; reaches 6-12 inches in height

Minimal watering except during establishment year. No supplemental feeding required. Prune lightly to encourage bushiness if desired
