Troubleshooting
'Sungold' Cherry Tomato problems — and how to fix them
'Sungold' Cherry Tomato (Solanum lycopersicum 'Sungold') 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
Thin-skinned Sungold cracks readily after a watering surge or rain; water evenly, mulch, and pick fruit promptly as it colours up.
Overgrown side-shoots
Extreme vigour means missed side-shoots quickly form a thicket; pinch them out weekly to channel energy into trusses.
Blossom-end rot
Dark, leathery base on early fruit from inconsistent moisture; stabilise watering rather than adding calcium supplements.
Aphids and whitefly
Sap-suckers cluster on soft tips, especially under glass; encourage predators, blast with water, or use insecticidal soap early.
