Growing waterlily in pot, leaves getting smaller
My parent just started growing waterlilies in pot, several growing really well. But the white waterlilies start to grow fewer and smaller leaves, the algae in the pot starts to grow wildly too. We were inform by the vendor where we bought the plants that white waterlilies are harder to grow.
I would like to know, is there anyone have same issues? Or have solution to this?
Thanks in advance.
