Watermelon Peperomia is a beautiful plant that’s perfect for growing in a large terrarium. It features lovely variegated foliage, with white streaks radiating out from the central stem to match the curve of the leaf shape itself. It makes for an excellent background plant or ground cover, depending on the size of your terrarium container. At full size, the Watermelon Peperomia is typically only 6-8 inches across, although that can still be too large for some terrariums.
It tends to prefer indirect sunlight, meaning that it will survive quite well in the terrarium environment as long as it is near a window or other light source. Even at the window, however, it’s important to ensure that it doesn’t get too much direct sunlight, as this can cause the sharp distinctions between the colour variegations to begin to fade, which makes the plant somewhat less appealing.When planting, be sure that you have included adequate drainage at the bottom of your terrarium by using pea gravel and charcoal, as the Watermelon Peperomia will quickly turn to rot if any water pools at the bottom of its container around the roots. The Watermelon Peperomia will do well in most soil types, including the terrarium standard peat moss blend.
