Instructions
Lay down a 2- to 3-inch layer of sand or small gravel. Dwarf sag does better with small gravel than with larger stones. If you prefer to use medium or large gravel, you can still plant dwarf sag, provided you lay down a layer of sand in the area where you want to plant.
Pick up the dwarf sag plant by its top and gently push the roots into the sand or gravel. Lift the plant up until the upper portion of the root crown lies just above the substrate.
Plant any additional dwarf sags in the same manner. For best results, dwarf sags should be planted at least 1 to 2 inches apart.
Watch the dwarf sag plants carefully for signs of problems, such as brown spots on the leaves or a general failure to thrive. You may need to add an iron supplement to the water or increase the wattage on your aquarium lights.
How to Plant Dwarf Sags in Aquariums
The plant known to science as Sagittaria subulata is known to aquarium hobbyists simply as dwarf sag. This attractive yet easy-to-grow plant is right at home in aquariums, and it is a good plant for new hobbyists to start with. The dwarf sag makes an excellent foreground decoration for the aquarium because of its grasslike appearance and the fact that it sometimes produces a lovely flower stem. You can plant dwarf sags individually or place them in clumps throughout the tank.
