Troubleshooting
Naranjilla problems — and how to fix them
Naranjilla (Solanum quitoense) 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.
Spider mites and aphids
Warm, dry air invites spider mites and aphids on the soft, hairy leaves, causing stippling and distortion. Raise humidity, inspect leaf undersides, and treat with insecticidal soap or horticultural oil.
Solanine in leaves and unripe fruit
As a nightshade, the foliage and green fruit are toxic and not edible. Only the ripe pulp is used; keep children and pets from chewing leaves or unripe fruit.
Heat and sun stress
Hot, exposed, dry conditions scorch and wilt the big soft leaves. Provide afternoon shade, mulch, and steady moisture to mimic its cool highland home.
Root rot and short lifespan
Waterlogged soil causes root rot, and plants naturally decline after a few years. Ensure excellent drainage and propagate fresh plants to maintain cropping.
Prevent naranjilla problems before they start
Most naranjilla issues are care-mismatch, not bad luck. Dial in the basics:
