Establishment
3-6 monthsYoung shrub with developing root system and initial growth of spiny foliage
Water regularly (weekly to bi-weekly) during first growing season. Apply 2-3 inches of mulch around base, keeping it away from stem. Prune lightly to shape if desired.
Vegetative Growth
1-2 yearsShrub develops dense, compact foliage with characteristic small, spiny, glossy leaves
Reduce watering frequency as root system expands. Minimal fertilizer needed. Prune in late winter to maintain shape and density. Apply small amounts of compost annually.
Flowering
2-4 weeks (spring)Inconspicuous small white or pale yellow flowers appear along branches (primarily on female plants)
Flowers are small and easily overlooked. Ensure male plant is nearby for pollination and berry production. No special care needed during flowering.
Fruiting
Fall through winter (4-6 months)Female plants produce abundant bright red berries that persist through fall and winter
Berries attract birds and wildlife. No special care needed. Berries provide seasonal color and wildlife food. Do not prune off berry-bearing branches if ornamental display is desired.
Dormancy
Winter monthsPlant enters minimal growth period during coldest months; foliage remains evergreen
No watering needed in zones 9-10 unless drought persists. In zone 8, provide light protection during hard freezes. No pruning needed unless damage occurs.

Spray with horticultural oil in early spring before new growth. Prune severely infested branches. Encourage natural predators.
-
Increase humidity with occasional overhead watering. Spray with water to dislodge mites. Use miticide only if infestation is severe; they rarely persist on drought-tolerant plants.
