Watch out for

Corm rot: Ensure well-drained soil and discard any damaged or rotting corms when dividing.

Gladiolus rust: Improve air circulation by dividing clumps and avoid planting in shaded, damp positions.

Red spider mite: Keep plants well-watered to reduce stress and spray with water or horticultural oil if infested.

Slugs and snails: Use slug pellets, copper tape barriers, or hand-pick pests at night to protect new growth.
