Troubleshooting
Discovery Apple problems — and how to fix them
Discovery Apple (Malus domestica 'Discovery') 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 pollination / no fruit
Discovery is not self-fertile and crops poorly without a compatible partner in flowering group 2-4. Plant another suitable apple nearby or rely on neighbourhood trees.
Short storage life
Fruit bruises easily and does not keep, going mealy within days of picking. Eat straight from the tree and pick a few at a time as they ripen.
Apple scab
Dark blotches on leaves and fruit in wet weather despite fair resistance. Clear fallen leaves and prune for airflow to reduce infection.
Codling moth
Caterpillars bore into the core, spoiling fruit. Hang pheromone traps from late spring and encourage predators to limit damage.
