Tall spikes topple
Large-flowered spikes are top-heavy and blow over easily. Stake each stem or grow in supported blocks in a sheltered position.
Thrips
Gladiolus thrips silver and streak leaves and spoil buds. Treat at first sign, inspect corms before planting, and store cleaned corms cool and dry over winter.
Corm rot / fusarium wilt
Wet soil and diseased corms cause basal rot. Use firm healthy corms, ensure sharp drainage, rotate beds annually and discard any soft corms.
Crooked or blind spikes
Spikes bend toward light or fail to flower if shaded, under-watered, or grown from undersized corms. Give full sun, steady moisture and plant large grade-1 corms.
