Mulberry vs Natal Plum Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Mulberry
Morus alba, Morus rubra, Morus nigra
Mulberries are deciduous trees or shrubs known for their edible fruits. They are typically medium-sized, reaching heights of 10-30 feet, though some varieties can grow larger. The leaves are alternate, simple, and often lobed, especially on young plants. While primarily outdoor trees valued for their fruit production, some people attempt to grow them in large containers. However, they require significant space and sunlight, making them challenging indoor plants. People grow them for the sweet, juicy berries, which can be eaten fresh or used in jams, pies, and other culinary applications.
Natal Plum
Carissa macrocarpa
Carissa macrocarpa, or Natal Plum, is a dense, evergreen shrub or small tree known for its glossy, dark green leaves and fragrant, star-shaped white flowers. It produces edible, plum-like red fruits that are rich in vitamin C. While it can be grown in containers, it's primarily an outdoor plant, thriving in warm climates. People grow it for its ornamental value, edible fruit, and use as a security hedge due to its thorny branches. It's not ideally suited as an indoor plant due to high light requirements and potential size.

❓ Frequently Asked Questions — Comparing These Plants
Mulberry
What are the light requirements for Mulberry?
Mulberry trees thrive in bright, indirect light. Insufficient light can lead to leggy growth and reduced fruit production (if applicable). Place your indoor Mulberry near a south- or east-facing window where it can receive several hours of sunlight each day. If natural light is limited, supplement with a grow light, positioning it about 12-18 inches above the plant. Rotate the plant regularly to ensure even light exposure on all sides. Be mindful of intense direct sunlight, which can scorch the leaves, especially during the hottest parts of the day. A sheer curtain can help diffuse harsh sunlight. Observe the plant’s growth; if it’s reaching towards the light source, it needs more light.
How do I care for Mulberry?
Caring for an indoor Mulberry tree requires a balance of attention to its specific needs. Provide bright, indirect light, ideally near a sunny window. Water thoroughly when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. Use a well-draining potting mix. Maintain moderate humidity. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer. Prune regularly to maintain desired shape and size, removing any dead or crossing branches. Repot every 1-2 years as needed, increasing pot size gradually. Monitor for pests like spider mites or mealybugs and treat promptly. Ensure adequate air circulation around the plant. Maintain consistent temperature and avoid sudden changes in environment.
How do I propagate Mulberry?
Mulberry trees can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from new growth in spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it moist. Cover with a plastic bag to increase humidity. Rooting should occur in a few weeks. Air layering involves wounding a branch and wrapping it in moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Once roots have formed, cut the branch below the moss and plant it in a pot. Keep in a shaded area and water regularly.
Natal Plum
What are the light requirements for Natal Plum?
Natal Plum requires ample sunlight to flourish and produce its characteristic blooms and fruits. Ideally, it should receive at least 6 hours of direct sunlight per day. In regions with intense sunlight, particularly during the hottest part of the day, providing some afternoon shade can prevent leaf scorch.
How do I care for Natal Plum?
Natal Plum thrives in full sun to partial shade. Ensure at least 6 hours of sunlight daily for optimal flowering and fruit production. Water thoroughly when the top inch of soil feels dry, allowing excess water to drain. Avoid overwatering, which can lead to root rot. Maintain moderate humidity, especially indoors.
How do I propagate Natal Plum?
Natal Plum can be propagated through stem cuttings. Take 4-6 inch stem cuttings from healthy, non-flowering shoots in spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a well-draining potting mix. Keep the soil moist and provide bright, indirect light. Rooting typically occurs within 4-8 weeks.
