I guess I'll have to start lurking around here .. I've been convinced by lotus pictures to make a container water garden. I've checked out some books at the library but there are some things that they are not answering or very clear on. First of all, they suggest kitty litter to hold plants down. Will any old kitty litter do? It seems the clumping and scented stuff would make a mess and not be very plant friendly, or is there a better substrate? Second, are there a certain size (depth and width) that is best for lotus? Third, are water pumps necessary (some in the books have them, other don't they don't really address the reason for them)? Fourth, I live in zone 8a and it can get into the teens at night for a few hours. Do lotus have to be "wintered over"?
Thanks! I'm looking forward to making my water garden and am enjoying reading your posts.
