Gardeners Delight Tomato problems — and how to fix them
Gardeners Delight Tomato (Solanum lycopersicum "Gardener's Delight") 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.
Fruit splitting
The small fruit crack after irregular watering or rain; keep moisture consistent and harvest as soon as fruit are fully coloured.
Side-shoots reducing the crop
As a cordon it sends out side-shoots in every leaf axil; pinch them out weekly to channel energy into fruiting trusses.
Greenhouse pests and botrytis
Whitefly and grey mould thrive in still, humid glasshouse air; ventilate well, use biological controls, and remove affected leaves.
Magnesium deficiency
Yellowing between the veins of older leaves is common in heavy-cropping potted plants; correct with an Epsom-salt foliar feed and balanced feeding.
