Gum Tree vs Lemon Balm Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Gum Tree
Eucalyptus spp.
Eucalyptus is a diverse genus of flowering trees and shrubs. Most are native to Australia and include over 700 species. They are known for their rapid growth, aromatic oils, and distinctive bark. Eucalyptus trees are primarily outdoor plants, grown for their shade, windbreak capabilities, and the essential oils extracted from their leaves. While some smaller species can be temporarily grown indoors, they require very bright light and specific conditions to thrive and often struggle to adapt. They are not ideal houseplants.
Lemon Balm
Melissa officinalis
Lemon balm is a perennial herb in the mint family, known for its lemon-scented leaves. It typically grows to a height of 30-60 cm (1-2 feet). The plant has a bushy growth habit and spreads via rhizomes. It is primarily grown outdoors for its aromatic leaves, which are used in teas, culinary dishes, and herbal remedies. While it can be grown indoors, maintaining optimal conditions for healthy growth can be challenging. People grow it for its calming properties and pleasant scent.

❓ Frequently Asked Questions — Comparing These Plants
Gum Tree
What are the light requirements for Gum Tree?
Gum Trees require bright, direct sunlight to thrive indoors. Aim for at least 6-8 hours of sunlight per day. A south-facing window is ideal, but east or west-facing windows can also work if supplemented with grow lights. Insufficient light can lead to leggy growth and pale leaves. If your Gum Tree is not receiving enough natural light, consider using a full-spectrum LED grow light to provide the necessary intensity. Rotate your plant regularly to ensure all sides receive adequate light exposure. Observe your plant for signs of light stress, such as scorched leaves (too much light) or elongated stems (too little light), and adjust its placement accordingly.
How do I care for Gum Tree?
Gum Trees thrive indoors with proper care. Provide bright, direct light, ideally from a south-facing window. Water thoroughly when the top inch of soil is dry, ensuring good drainage to prevent root rot. Use a well-draining potting mix and a pot that is appropriately sized for the root system. Maintain moderate humidity levels and a stable temperature between 60-75°F (15-24°C). Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune regularly to maintain shape and encourage bushier growth. Monitor for pests and address promptly. Repot every 1-2 years as needed. Consistent care is key to a healthy indoor Gum Tree.
How do I propagate Gum Tree?
Gum Trees can be propagated through stem cuttings and air layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem. 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 maintain humidity. For air layering, make a small incision on a stem, wrap it with moist sphagnum moss, and cover with plastic wrap. Once roots develop, cut the stem below the moss and plant it in a pot. Both methods require patience and consistent moisture. Rooting can take several weeks to months.
Lemon Balm
What are the light requirements for Lemon Balm?
Lemon Balm thrives in partial to full sunlight. Ideally, it needs at least 4-6 hours of direct sunlight each day to promote healthy growth and abundant flowering. When grown indoors, place it near a sunny window, such as a south-facing or east-facing window. If natural light is insufficient, supplement with grow lights to ensure adequate illumination. Insufficient light can lead to leggy growth and reduced flowering. Rotate the plant regularly to ensure even light exposure on all sides. Avoid placing it in excessively shaded areas, as this can weaken the plant and make it more susceptible to pests and diseases. A bright, sunny location is key to a thriving and fragrant Lemon Balm.
How do I care for Lemon Balm?
Lemon Balm is relatively easy to care for, making it a great choice for beginner gardeners. Provide it with partial to full sunlight, ideally 4-6 hours of direct sun daily. Water regularly, keeping the soil consistently moist but not waterlogged, especially during the growing season. Fertilize monthly with a balanced liquid fertilizer diluted to half strength to encourage blooming. Prune regularly to maintain shape and prevent it from becoming leggy. Lemon Balm prefers well-draining soil rich in organic matter. Maintain a humidity level of 40-60%. Repot annually in spring to refresh the soil. Monitor for pests like aphids and spider mites, and treat promptly if detected. In colder climates, protect the plant from frost by bringing it indoors or providing adequate insulation. Deadhead spent blooms to encourage further flowering.
How do I propagate Lemon Balm?
Lemon Balm is easily propagated through several methods. Division is best done in spring or fall by carefully separating the root ball into smaller sections and replanting them. Stem cuttings can be taken in spring or summer; cut a 4-6 inch stem just below a node, remove the lower leaves, and place the cutting in water or directly into moist potting mix. Keep the soil consistently moist until roots develop, which usually takes a few weeks. While Lemon Balm doesn’t produce keiki, its vigorous growth allows for abundant cuttings. Ensure cuttings receive bright, indirect light and a humid environment to encourage rooting. Once rooted, transplant into individual pots. Propagation ensures a continuous supply of this fragrant and useful herb.
