Troubleshooting
Pineapple guava problems — and how to fix them
Pineapple guava (Feijoa sellowiana) 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 fruit set
Most cultivars are self-fertile but cropping improves dramatically with two different cultivars nearby for cross-pollination. Hand-pollinate flowers if bees are scarce. Also ensure full-sun siting and adequate water during fruit development.
Frost damage to flowers
Late spring frosts can destroy flower buds and developing fruitlets even when the plant itself is unharmed. Grow in a sheltered, south-facing spot or against a wall in marginal UK zones (H3). Fleece-protect during unexpected cold snaps in flower.
Root rot in wet soil
Feijoa will not tolerate waterlogged or poorly drained ground. Yellowing leaves and dieback in wet winters signals root rot. Plant on a slight slope, raise beds, or add grit to improve drainage before planting.
Prevent pineapple guava problems before they start
Most pineapple guava issues are care-mismatch, not bad luck. Dial in the basics:
