Choose a water lily according to the eventual spread of its leaves and the depth of your pond. Compact and miniature varieties are suitable for small ponds and containers, while vigorous varieties need substantially more surface area and deeper water.

Planting depth varies by variety. Newly planted water lilies can initially be positioned in shallower water, sometimes by raising the basket on bricks, and then lowered gradually as the leaves grow towards the surface. Check the recommended final depth for the specific variety.

Most water lilies flower best with plenty of direct sunlight. A pond in heavy shade may produce fewer flowers, although requirements vary between varieties. When choosing a water lily, consider both the available sunlight and the mature size of the plant.

es. There are compact and miniature water lilies bred for small ponds, tubs and other container water features. Avoid choosing a vigorous full-sized variety for a small pond, as it can quickly cover too much of the surface.

Poor flowering can result from insufficient sunlight, overcrowding, an unsuitable planting depth or lack of nutrients. Established water lilies may need dividing and repotting when congested, and plants that flower poorly may benefit from an appropriate aquatic fertiliser where feeding is required.

The best wildlife pond plants provide a mixture of underwater cover, surface shade, flowering habitat and places for aquatic insects to emerge. A balanced pond can include oxygenating plants, marginal plants and floating-leaved plants such as water lilies. Native species are particularly useful for supporting UK pond wildlife.
