I want to start planting water lilies and lotuses in my pond but I'm not sure when exactly would be the best time to do that. I am zone 6b and the last frost will be the end of May but can I start planting now because the water will no longer freeze?
Also, the bottom of the pond is natural and there is a thick mat of growth/weeds dense enough to walk on. I dragged much of that out when digging out the pond but I am concerned that it might eventually strangle my lilies/lotuses. Can I plant the bulbs directly in the soil or do I need to plant them in a container?
