Growing Lotus Flower plant | Ornamental gardening | Commercial Hydroponics farming in India

Hi

I have always had a dream of growing lotus plants and see a lotus bloom at my home 🙂

I was lucky to get a lotus plant from my friends native and could get them survive in a small container:

I need help how to transfer them to a bigger container. What should be the soil composition? how to maintain the water level?

How big should be the container?

Any help on these ugently please.....

Regards

Prasad
