Troubleshooting
Pinemat manzanita problems — and how to fix them
Pinemat manzanita (Arctostaphylos nevadensis) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Poor establishment at low elevations
This high-elevation species dislikes summer heat and humidity at lower altitudes. Below 600 m, provide afternoon shade, excellent drainage, and cool root conditions. Mulch with gravel to keep crown dry and cool.
Root rot in compacted or poorly drained soil
Phytophthora root rot is the primary disease risk, triggered by warm wet soils. Plant in raised beds or slopes and avoid any summer irrigation once established. Sandy or gravelly substrates are strongly preferred.
Transplant sensitivity
Like all manzanitas, pinemat resents root disturbance. Plant from small containers in autumn; do not bare-root transplant. Avoid amending the planting hole with moisture-retaining organic matter.
Prevent pinemat manzanita problems before they start
Most pinemat manzanita issues are care-mismatch, not bad luck. Dial in the basics:
