🌱 How to Care for Gladiolus to Prevent Mealybugs?
💧 How to Water
Give about 2.5 cm (1 inch) of water per week when it does not rain, soaking the soil deeply rather than sprinkling. Keep the soil evenly moist from spike formation to flowering, since drought shortens the flower spike. Avoid waterlogging, which rots the corms, and keep watering while the leaves stay green after flowering.
☀️ Lighting
Needs full sun, at least 6 hours of direct light a day. In shade the plants lean, the spikes are weak and some corms do not flower at all. Choose a spot sheltered from strong wind, which knocks over the tall spikes.
🪴 Ideal Soil
Loose, fertile, well-drained loam or sandy loam with organic matter, pH 6.0-7.0. Heavy clay should be improved with compost; soggy soil causes corm rot.
