Waterlily Care

Planting

pond plants We recommend that, for ease of maintenance, all lilies should be planted into mesh planting baskets or crates. 
pond plants Most water lilies should be potted into a 10ltr container.
pond plants Use ordinary heavy garden loam.  If you can squeeze a handful of soil into a ball, throw it up and catch it without it breaking up, the soil is the right consistency.
pond plants Plant into a heavy loam, free from chemicals. Neither light, sandy soil, chalk nor raw clay is suitable. NEVER add peat or compost to the soil.
pond plants Fill the basket ¾full of soil, pressed well down to make it really firm.
pond plants Place the rhizome on the surface of the soil with any shoots uppermost.
pond plants Fill with soil, again really firmly pressed into place, so that the rhizome is exposed at the growing point of the shoots.
pond plants Top dress with 1-2cms washed pea gravel.

Positioning Your Waterlily

pond plants To obtain the greatest number of flowers throughout the flowering season (June/September), place in the sunniest part of the pond.
pond plants Always introduce a new plant in stages, never plunge a young plant straight into the maximum depth of water.
pond plants For a young plant, or new introduction, there should be no more than 20-25cms of water over the gravel. With larger lilies, as the leaves grow and separate, gradually lower the
basket until the full depth is achieved.
pond plants Lilies do best in warm, sunny conditions, so ideally should be planted no deeper than 45-60cms deep (to the top of the basket).
pond plants NEVER put a lily beneath a fountain, they hate being constantly splashed and it can even kill them!
pond plants Always position plants well away from pumps, filtration inlet/outlets, moving water and fountains. 

Displaying your Watelilies
Lilies are best displayed with clear water showing all round the plant. When choosing the variety and number of water lilies you should consider the following:-

pond plants The overall size of your pond i.e. in optimum conditions you will require one plant for every 1½-2 m² of surface area 
pond plants The mature size and vigour of the plant you choose i.e. you may wish to display one specimen lily rather than two or three medium lilies or several small lilies.
pond plants The depth of your pond, i.e. you may need to use blocks or other supports to raise planting crates to the optimum planting depth.
pond plants Any factors which might restrict the growth of you plants such as shade, filtration, or water features. 

Waterlilies: size x planting depth


Size Ideal Depth Maximum Depth
LARGE L 46cm (18in)  90cm (36in) 
MEDIUM M  30cm (12in)  60cm (24in)
SMALL S 20cm (8in)  30cm (12in)
PYGMY P 15cm (5in) 18cm (7in)

These depths are a very general guide.
