having many small leaves crop up maybe it is because you have several crowns growing out of that rhizome?
Have checked now and it is true. Not such a big rhizome but has 5 small crowns on it. Thanks for your hit.
Regarding fertilizer, well I used the same for all and others are quite good. Actually as I mentioned before I have used NPK 18-46-0, just to try and see. My other pots have large leaves and flowers, they are very fine.
For normal terrestrial plants, if I am not wrong;(pls correct me)
N-Nitrogen is good for green parts
P-Phosphorus is for roots, stem and good flowering
K-Potassium is for tasty and durable fruits
How do we apply this for aquatics ie. w.lilies?
I would like to see the negative effects of missing "K" , if any, with my fertilizer mixture. All, except this one pot mentioned above, have lots of leaves (most of them with diameter 9-11"), long and many roots and good looking flowers staying open 3-4 days.
What part of w.lilies and lotuses needs K-Potassium, in other words.
Thanks in advance.
