Are the mounds I put the iris on ok? Someone reminded me that it would help with drainage in the raised beds - I don't think they're too high but maybe a rock on the back part will help prevent winter heaving?
Second question is about one or two that I planted VERY high out of the soil and I'm thinking it's too high - but planting them deeper will cover up the increases. Is it ok to cover the small increases with soil or will they die off if covered completely? I know these sound like ridiculously basic questions but I want to be sure - none of my local friends grow iris at all. Thanks!
