Potting Waterlilies

Well I bought another water lily and it wasn't even on clearance yet. Supplies needed for potting up water lilies: Water Lily Bulb - Offset from existing tuber, or a new one New Pot, sized for lily (bulb pan used in example) Cat Litter Pans Kitten sized seem to work well too. Something to block holes if needed (I used a piece from a net pond plant pot) Enough Clay Cat Litter to 3/4 fill the pot (MUST BE PURE CLAY NO CLUMPING OR PERFUMES) This is the kind I've used before. Smallish Aquarium Gravel to cover about 1/2 - 1 inch unless you have Koi, which may require a heavier rock size to keep them from digging. Tuber as packaged. I only once made the mistake of dropping one of these plants directly in. They spread roots every where, and when they get huge getting the plastic mesh off is quite a chore. At this size they pop right out. Make sure any tuber you buy is firm. If they have sat around for too long and gotten too dry they tend to molder, if wet sometimes they rot and turn to mush. Cover any holes in your pot with mesh, this is from a pop up grow bag I tried once. Never again the lily roots grow right out all over the place anyway. They're great for filling holes though. 3/4 fill with cat litter. Position the bulb on top with the cut end on an edge and the growing tip aimed at the open space in the pot. If you have one with roots they should be buried as you pour in the cat litter. I put a small amount of gravel in the bottom, just enough to keep the liner from raising, dry cat litter is too light to hold it down. Cover over with a small amount of gravel. Keep the growing tips free of gravel and above the gravel height. Some of the rootless cuttings have a tendency to float, so you may have to hold it down with a U shaped pin, or gently place a few larger rocks on it.
