We use squat pots or aquatic pots here on our farm. These type of pots are shorter and have no holes in them. If you have regular pots this will work, just plug up the holes so the nutrients and the dirt won't leach out into your pond. Some of our customers like to use the aquatic baskets, these are fine, however they are more expensive, the choice is yours. We suggest 2 gallon squat pots for medium to large lilies and 1 gallon squat pots for small and dwarf type lilies.
Lilies grow best in rich garden soil, and clay like soil is even better.
Be sure there is no peat moss, humus, or chips of wood in your soil this will make a mess and rot under water, this could cause some problems in your pond. You can use kitty litter also however be sure it has no perfumes or chemicals added to it, and you will have to fertilize our plants more often if you chose to use this type of soil. Now you are ready to plant your lilies. We suggest you soak your pot first before planting, and be sure to pack the soil down as hard as you can while soaking. We need to explain at this point that you do not want to cover the Crown.
