The Begonia Julau plant is native to Malaysia, so it thrives in high heat and humidity conditions. A terrarium is the best place to grow your plant, providing a consistently moist environment for it to live. However, your plant’s roots must not be in very saturated soil.
The Begonia Julau likes sunlight, but indirect light is the best way to go. Without enough sun, you may notice your plant turning yellow or dropping some of its leaves.
A high-quality, well-draining potting soil with compost will promote a moist environment that doesn’t get overly saturated. If you would like to build up the drainage of your soil, moss can be used in terrariums.
