🌱 How to Care for Chilean Gunnera to Prevent Slugs and Snails?

💧 How to Water

Keep the soil constantly moist, almost boggy, throughout the growing season -- this plant naturally grows along streams and lake edges and sulks badly if it dries out, though watering should ease off considerably in cold, dormant winter conditions.

☀️ Lighting

Partial shade with dappled sunlight brings out the healthiest leaf colour and size, especially in hot climates; young plants scorch easily in strong sun, though larger, well-established clumps can tolerate more direct light if kept consistently moist.

🪴 Ideal Soil

Plant in deep, rich, humus-laden soil that holds moisture without turning waterlogged -- heavy mulching with compost or manure each spring recreates the boggy, nutrient-rich streambanks this species calls home in Chile.
