Why Use Colocasia in a Water Garden?
- Thrives in Wet Conditions – Unlike many plants, Colocasia can grow in shallow water or consistently wet soil.
- Creates a Tropical Look – The oversized leaves provide a lush, jungle-like appearance.
- Natural Water Filter – Helps absorb excess nutrients, reducing algae growth.
- Attracts Wildlife – Can create a habitat for beneficial insects, frogs, and birds.
How to Plant Colocasia in a Water Garden
1. Choose the Right Variety
Not all Colocasia varieties can be submerged in water. The Giant Colocasia Gigantea is an excellent choice for ponds, as it tolerates wet soil and shallow water.
2. Select the Best Planting Method
Colocasia can be grown in water gardens in two ways:
- Potted in Aquatic Containers – Place the plant in a pot filled with heavy clay soil and submerge it 1-3 inches below the waterline. This allows control over soil nutrients while preventing root spread.
- Planted in Shallow Water or Bog Areas – In natural ponds or marshy areas, Colocasia can be planted directly in the margins of a pond or areas with consistently wet soil.

- Light Requirements – Colocasia grows best in full sun to partial shade.
- Water Depth – Keep the base of the plant in shallow water (no deeper than 4 inches).
- Fertilization – Use a slow-release aquatic plant fertilizer to promote strong growth.
4. Maintain and Prune as Needed
- Remove old or yellowing leaves to keep the plant looking fresh.
- Trim excessive growth to prevent overcrowding in your water garden.
- If temperatures drop below 50°F, consider moving the plant to a pot for indoor overwintering.
