can i buy water lettuce at home depot store or a garden store?
most likely a garden store. i don't think home depot sells aquatic plants
I am nt familiar with what water lettuce is, but looking at the other answers..our home depot here sells aquatic plants..some mentioned they do not...The one here (Panama City,Florida) has one of the fish ponds that they sell in the store set up displaying the optional water pond features you can buy( cranes, frogs etc spitting water) and they have aquatic plants for sell in the functioning pond..I would guess they are all different in alot of aspects..so call your local home depot and ask them would be my suggestion..
In the spring when the pond plants come in you can buy water lettuce at most any place that sells water garden supplies and plants, including Home Depot and Lowes. I have bought them at both places. Most nurseries and garden centers that have water garden supplies have them also.
Not at Home Depot, go to a garden store or nursery.
