🌱 How to Care for Canna lily to Prevent Slugs and Snails?
💧 How to Water
During the growing season, keep the soil consistently and evenly moist—water deeply 1–2 times per week—but avoid standing water and waterlogged soil, as this promotes root and rhizome rot.
☀️ Lighting
Requires as much direct sunlight as possible (ideally more than 6 hours a day); in shadier spots, the foliage remains a lusher green, but flowering will be sparse and the stems may become leggy.
🪴 Ideal Soil
Use loose, well-draining soil rich in humus and organic matter, with a neutral to slightly acidic pH (approx. 6.0–7.0); avoid permanently wet, compacted soils.
