Care tips
It requires full sun for optimal flowering and well-drained soil, rich in organic matter. Watering should be regular during the growing and flowering period, keeping the substrate moist but not waterlogged. Plant the corms at a depth of 10-15 cm with similar spacing. A common mistake is not providing support for tall varieties, which can cause the floral spikes to bend or break in the wind.
How to save a dying Gladiolus
- Warning signs
- Yellow or wilted leaves, soft or rotten stems at the base, lack of flowering or deformed flowers.
- First aid
- Check the corm: if soft or foul-smelling, cut off rotten parts with a clean, disinfected knife. If healthy, replant in fresh, well-draining soil. Reduce watering immediately.
- What kills it
- Overwatering, especially in heavy soils, quickly rots the corm. Also, insufficient light.
- Can it be saved?
- Yes, if the corm is not completely rotted. Act quickly at the first signs of rot.
