The lotus plant is a beautiful addition to any pond or water garden. These plants can grow quite large and produce beautiful, though short-lived flowers. Sprouting and planting lotus takes a little bit of work because there are many ways that the plant can be damaged or killed. Lotus can be planted outside in the spring, or can be started indoors in the fall or winter and then transplanted outside in the spring. They require more than six hours of sunlight a day.
Grip the seed in the pliers. You will see that the seed has two ends, one dimpled and one pointed. Hold the seed so that the side is exposed.
Use the sandpaper to sand the seed until a white line, circle, or oval appears. Check the seed frequently while sanding. Be careful not to sand beyond this point.
Fill the large bowl with water, rainwater being preferable. This water should be kept between 70 and 90 degrees Fahrenheit. Let the seed float in this water for up to 30 days, and change the water about twice a day or as necessary in order to prevent scum from forming.
Keep a close eye on the seedling once it has sprouted. It is not necessary to plant the seedling until roots begin to grow, but it is important to plant it once they begin to do so.
When the seedling is ready to plant, fill the pan to a depth of 4 inches with a mix of half garden soil and half commercial topsoil. Alternatively, you can use heavy loam. Plant the seedling so that the sprout is above the level of the soil.
Use the small rocks to weigh it down without obscuring the sprout. Cover the remainder of the soil with 2 inches of gravel.
Fill up the pan so that the sprout is under water by about 2 inches.
Let the tuber soak in warm aged pond water for 10 to 14 days. This will cause it to sprout.
Place 4 inches of soil in the pan. Put the tuber on the soil, pushing it down only slightly. Weigh the tuber down with small rocks.
Spread 2 inches of gravel on the soil, taking care to make sure that the eye (or growing part) of the tuber remains exposed and pointing upward.
Fill the container with water to a depth of 4 to 6 inches. Keep the water warm and make sure that the plant gets more than six hours of sunlight daily.
