Dwarf Cattail is a hardy bog plant. A good grower that will spread quickly, hardy zones 3 - 12. Fertilize: 1 tablet monthly. The net pots are designed to split apart as the plants matures. Plant as you would the lilies with heavy loam soil, but when adding fertilizer tablets, use 1 tablet for 1 gallon size pots and 2 tablets for 2 or 3 gallon size pots.
