Dwarf French Bean problems — and how to fix them
Dwarf French Bean (Phaseolus vulgaris 'Safari') 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.
Flower drop
Heat stress or dry soil makes flowers fall without setting; keep moisture even and mulch in hot spells.
Botrytis on dense plants
Grey mould on crowded, damp foliage; thin and space plants and avoid overhead watering in wet weather.
Slug-eaten seedlings
Young dwarf plants are easily stripped at ground level; protect transplants and sow into warm soil so seed germinates fast.
Gluts and gaps
A single sowing crops in a short flush then stops; sow small batches every two to three weeks for a steady supply.
