Growing Marginal Plants

Blue Irises

When planting marginals, use individual containers of approximately one to three-gallon capacity. Some marginal plants are grown in two-inch net pots, and it’s best to leave these net pots to avoid damaging the roots. Fill the pot half full with rich garden soil and add one fertilizer tablet for one-gallon size pots and two tablets for two or three-gallon size pots; then continue to fill the pot with soil to about two inches from the top. Marginal plants should be lowered to a depth of only one to three inches. They grow out of the water and are usually found at the water’s edge.
