Good day. I'm sorry if this question has been asked before.
I bought three red tiger lotus and the largest one of them does not have a bulb. It has healthy roots and is already growing new leaves. My question is will it grow a new bulb? tyvm
Right at the merge between the roots and the leaves' petiole. That should be half in the substrate half above. The bulb is a nutrient storage organ so as the plant is fed more than it needs it will build a larger bulb.
