My son bought a lotus plant and it had leaves when he bought it but no new leaves since than, it has been more than a month! Any suggestions of what I should do with the big tub under water in the pond, I put 4 fertilizer tablets per the Koi store but no luck so far. Any suggestions I would appreciate! This is not the 1st time my adult son has abandoned the pond he built in my yard 15 years ago that I try to keep going cause I love it! Just another duty as a Grandma!
