So I recently bought red rotala indica and had a few questions on it. The ones I bought arent very red and are more on the lime side of coloration. One of them does habe a little pink coloration but its only near the top. Also when I look up how large the plants grow i see 6 inches, but my stems are 14 - 18 inches. Finally, how do you propagate these plants ? Can I cut them wherever, and when planting them in substrate do I bury up to the roots and stop when it get to the stem ?
