Indoor Citrus Trees - Tips For Growing Citrus Houseplants
Plant the citrus tree in soil with a considerable amount of organics such as leaf mold, peat moss (use peat in the soil mix to keep the pH down), or compost. A mix of one-third sterile potting soil, one-third peat, and one-third organic matter works well. Relative humidity is an important factor in the growth of citrus.
