      Till 4 inches peat moss, 3 inches aged compost and 1 inch perlite into the soil in your garden bed before planting the neptunia dimorphantha seed. Incorporate the organic materials to a depth of 6 inches.

      Irrigate the garden bed with up to 1/2 gallon of water to moisten the soil after planting. Continue to provide the plant with regular supplemental irrigation while it is actively growing and flowering. Give neptunia dimorphantha up to 1 gallon of water each time you irrigate. Maintain soil that's moist, but never waterlogged.
