Select two to five different species. Plant same species together. Use locally grown and adapted plants whenever possible. Other wastewater treatment technologies may be more appropriate for heavily shaded sites that cannot be modified. Do not select soft tissue ornamentals, such as lilies, for the treatment area.
Planting Make sure that the plants are free of disease and mold.
Keep roots moist at all times. Plants should be inserted into the pea gravel bed to a depth of 2 to 4 inches with the shoots slightly exposed. Roots must be placed in water. Planting should be done six weeks prior to building occupancy. Rows may be 18 inches apart and staggered 9 inches.
