Care tips

This gladiolus thrives in full sun, requiring at least 6 hours daily for optimal flowering. It needs regular and ample watering during its growth and flowering period, especially in hot and dry climates; avoid letting the soil dry out completely. It prefers well-drained soil rich in organic matter. A common mistake is planting it in heavy, poorly draining soils, which can lead to corm rot.
