Lemon Lime Prayer Plant is considered to be an easy, low maintenance houseplant with symmetrical, bright green lines on the leaves. Because Lemon Lime is a prayer plant, it has the ability to fold its leaves at night. Like other prayer plants, Lemon Lime prefers indirect light and tolerates low light conditions. Water when the soil drys out and make sure to keep the humidity levels medium to high. Lemon Lime is a slow growing houseplant, repot every other year or when the roots grow out the drainage holes. Use an organic potting mix and since Lemon Lime prefers the soil to be slightly acidic, add a tablespoon of coffee grounds once a month as a natural fertilizer.
