Troubleshooting
Canistel problems — and how to fix them
Canistel (Pouteria campechiana) 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.
Frost and cold damage
Tender to cold; foliage suffers near freezing and young trees can be killed by frost. Overwinter containers in a frost-free, bright space.
Chalky, unpleasant unripe fruit
Eaten before fully ripe, the flesh is hard, astringent and gummy. Let fruit soften fully off the tree for the characteristic sweet, custard-like texture.
Iron chlorosis on alkaline soil
On high-pH limestone or chalky soils new leaves can yellow between green veins. Apply chelated iron and micronutrient feeds to correct it.
Scale and fruit flies
Scale insects infest stems and leaves while fruit flies attack ripening fruit. Use horticultural oil for scale and harvest or bag fruit to limit fly damage.
Prevent canistel problems before they start
Most canistel issues are care-mismatch, not bad luck. Dial in the basics:
