Growing tips to make waterlilies flower:
1. Sun:
- Waterlilies are very sun dependent so should be placed in as much sun as possible.
2. Water depth:
- Each named variety has a depth requirement - some Pond waterlilies will grow well with 36" of water over the 3 litre basket, others will struggle with more than 24" of water over the top of the basket.
- Double Pond waterlilies such as Nymphaea Gonnere and Madame Wilfron Gonnere like to be nearer the surface than other waterlilies of a similar spread.
- Dwarf and miniature lilies only need 6" of water over the top of the 1 litre basket they are supplied in.
- The crown of the plant (at the top of the basket) needs to be below potential ice depth but need not go down to its final depth immediately.
-
- dense, flat growing leaved waterlilies
3. Splashing water:
- Do not place waterlilies near splashing water such as a waterfall, fountain or pump outlet.
-
- waterliliy leaves standing above water surface
4. Fertiliser:
- The Pond waterlily has a heavy nutrient requirement and needs a boost from aquatic fertilizer every year - add XL fertilizer balls to the basket of an established 3 litre plant in Spring.
- Add one small fertilizer growth ball to a 1 litre basket of a Dwarf or Miniature waterlily in Spring.
5. Repotting:
- Your Pond waterlilies may be congested so need repotting. A sure sign is if the leaf does not lie flat on the surface but stands upward out of the water. See 'Repotting a waterlily'
