How to Grow Manzanita
Arctostaphylos manzanita
Manzanita thrives in full sun with sharp drainage and no supplemental water once established. Plant in lean, well-drained soil — never amend with compost or fertilise. The distinctive smooth mahogany bark and clusters of winter flowers make it a stunning year-round specimen.
Yearly Lifecycle
Care Essentials
No regular feeding needed. Manzanita is native to poor, well-drained soils and thrives without fertiliser. Feeding promotes weak, leggy growth.
Watch For
- Phytophthora root rot (in wet soil)
- Leaf gall (Exobasidium)
- Aphids
Track your Manzanita care schedule — pruning, feeding, and seasonal tasks

☀️ Light
Full sun essential — at least 6 hours direct sun
Full sun is essential for manzanita. At least 6 hours of direct sunlight daily. Plants become leggy and disease-prone in shade. South or west-facing positions ideal.
💧 Watering
Drought-tolerant once established; no summer irrigation
Drought-tolerant once established (after 2 years). Water deeply but infrequently during the establishment period. After that, NO summer irrigation — rainfall is sufficient. Overwatering is the primary cause of death.
🌱 Fertilizing
Do NOT fertilise — native plants adapted to poor soil
Do NOT fertilise. Manzanita evolved in nutrient-poor soils and thrives without amendments. Fertiliser promotes weak, disease-prone growth and disrupts the natural compact habit.
✂️ Pruning
Minimal — remove dead wood in late winter only
Minimal pruning required. Remove dead wood in late winter and lightly shape if needed. Never hard-prune manzanita — it does not regenerate well from old wood. The natural form is part of its beauty.
🍂 Mulching
Gravel or decomposed granite preferred; avoid organic bark mulch
Gravel or decomposed granite preferred around the base. Avoid organic bark mulch directly against the trunk as it retains moisture and promotes rot. Keep all mulch a few inches from the trunk base.
Growing Tips
Never overwater
Root rot from Phytophthora is the number one killer of manzanita. Once established, water only during extreme drought. In normal conditions, rainfall is sufficient.
Sharp drainage is non-negotiable
Plant on slopes, raised beds, or amend with gravel to ensure water never pools around roots. Clay soil is a death sentence for manzanita.
Do not fertilise
Manzanita evolved in nutrient-poor soils. Fertiliser promotes soft, disease-prone growth and ruins the natural compact habit.
Admire the bark
The smooth, exfoliating mahogany-red bark is the star feature. Avoid damaging it with ties or supports — let the natural sculptural form develop.
Pests & Diseases
Pest Aphids
Identification: Small clusters of green or black insects on new growth and flower buds. Sticky honeydew on leaves.
- Blast off with a strong jet of water
- Encourage ladybirds and lacewings
- Insecticidal soap spray if severe
Pest Whitefly
Identification: Tiny white flying insects that rise in clouds when foliage is disturbed. Found on leaf undersides.
- Yellow sticky traps nearby
- Encourage parasitic wasps
- Insecticidal soap or neem oil spray
Disease Phytophthora Root Rot Phytophthora spp.
Symptoms: Sudden wilting, yellowing leaves, branch dieback. Crown and roots show dark, water-soaked lesions. Often fatal.
Treatment: Remove and destroy affected plants. Improve drainage. Do not replant manzanita in the same spot.
Prevention: Never overwater. Ensure sharp drainage. Avoid irrigation on established plants. Keep mulch away from the trunk base.
Disease Leaf Gall Exobasidium spp.
Symptoms: Thick, fleshy, pale green to white swellings on leaves and stems in spring. Galls turn brown and dry as the season progresses.
Treatment: Pick off and destroy galls before they turn white and release spores. Usually cosmetic — does not harm plant health.
Prevention: Good air circulation. Remove fallen galled leaves.
