Growing tips to make waterlilies flower:
- 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.
3. Splashing water:
- Do not place waterlilies near splashing water such as a waterfall, fountain or pump outlet.
- 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.
- 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’
