In my earlier post http://gardentowok.com/harvest-monday-january-23-2012-growing-sweet-potatoes/ I forgot to mention which end of the sweet potato should be immersed in water.
How to tell? There are 2 ways:
1. Observe the sweet potato, if there are hairlike roots, notice which direction the roots are growing. Photo at right shows the hairlike roots growing downward (it is the thin line on the left of the photo). Place the end that the roots are growing towards in the water (in this photo it would be the lower section).
2. If there is no hairlike roots, then observe the 2 ends of the sweet potato. The root end has a sharper point (photo lower section) this is the end to immerse in water. The stem end has a flat scar (photo upper section) this is the end that was attached to the growing vine and should be facing up.
