Grow red aglaonema in low, medium, or bright light. The plant often shows the best color in medium or indirect light indoors. In most areas, it can take some direct sun on the leaves, but in the Deep South, it's best to diffuse strong sun with a sheer curtain.
Water red aglaonema when the soil dries out. This houseplant can go a few weeks without water if you're away from home or get too busy to water. But it does grow best when watered regularly.
Fertilize red aglaonema a couple of times a year to keep it at its best. You can fertilize more frequently if you wish. Use any houseplant fertilizer and be sure to follow the instructions on the product packaging.
