Betel leaf needs regular watering to grow. Once it grows and reaches at least two meters in height, you should start pruning the plant. This will encourage the plant to grow new sweet and tender leaves. When the plant is in the growing season, it is highly recommended that you feed every couple of months. It prefers nitrogen enriched organic fertilizer. It is also possible to use a manure or a compost.
Since it is native to Asia, betel leaf prefers a warm climate. If the temperature falls to 41F degrees and under in winter, it is better to bring the plant indoors. You should place it in a warm area and for better results, you could use grow lights. Cold climate is harmful to the plant, it will make it go dormant and it will eventually shed its leaves.
