Why do my waterlilies not flower?
Firstly, waterlilies are very sun dependant so they need to be placed in as much sun as possible. Each named variety has a depth requirement – some will grow well with 36″- 48″ of water over soil, others will struggle with more than 24″ of water over soil and miniature lilies only need 6″ of water over soil. Thirdly, do not place them near splashing water such as a waterfall, fountain or pump outlet. If none of these seem to solve the problem perhaps the plant needs a boost from some fertilizer – add aquatabs to the basket or in a patio container pond add aquatic food plus to the water.
