Apple vs Catnip Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Apple
Malus domestica
The apple tree (Malus domestica) is a deciduous tree known for its fruit, the apple. It typically grows to a height of 3-12 meters with a broad, spreading crown. Apple trees are not naturally indoor plants and require specific conditions to fruit. They are grown for their fruit production, ornamental value (spring blossoms), and shade. Indoor cultivation is extremely challenging and rarely successful in producing fruit due to light, temperature, and pollination requirements.
Catnip
Nepeta cataria
Catnip is a herbaceous perennial plant known for its intoxicating effect on cats. It typically grows to a height of 50-100 cm, featuring grayish-green, heart-shaped leaves with serrated edges. The plant produces spikes of small, white or pale lavender flowers dotted with purple spots. While primarily grown outdoors, it can be cultivated indoors with sufficient light. People grow it for its appeal to cats, its use in herbal teas, and its purported medicinal properties.

❓ Frequently Asked Questions — Comparing These Plants
Apple
What are the light requirements for Apple?
Apple trees require a significant amount of light to thrive indoors. Aim for at least 6-8 hours of direct sunlight per day. A south-facing window is ideal, but an east or west-facing window may also suffice if the light is strong enough. If natural light is insufficient, supplement with grow lights. Position the grow lights 6-12 inches above the tree and use them for 12-16 hours per day. Rotate the tree regularly to ensure even light exposure on all sides. Insufficient light can lead to leggy growth, reduced flowering, and poor fruit production. During the winter months, when natural light is reduced, consider increasing the duration of grow light use.
How do I care for Apple?
Growing an apple tree indoors requires careful attention to several key factors. First, select a dwarf variety suitable for container growing. Use a well-draining potting mix specifically formulated for fruit trees. Provide at least 6-8 hours of direct sunlight daily, or supplement with grow lights. Water thoroughly when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. Fertilize regularly during the growing season (spring and summer) with a balanced fertilizer formulated for fruit trees. Prune regularly to maintain shape and encourage fruiting. Maintain a stable temperature between 60-75°F (15-24°C) and provide adequate humidity. Consider hand-pollinating the flowers to increase the chances of fruit production. Repot every 2-3 years into a slightly larger container. Monitor for pests and diseases, and treat promptly.
How do I propagate Apple?
Apple trees can be propagated through stem cuttings or air layering, though grafting is the most common method for fruit production. For stem cuttings, take a 4-6 inch cutting from a healthy branch in late winter or early spring. 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. Roots should develop in 6-8 weeks. For air layering, make a shallow cut in a branch and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Keep the moss moist. Roots should develop in a few months. Once roots are visible, cut the branch below the roots and plant it in a pot. Grafting is more complex and requires specific skills and materials.
Catnip
What are the light requirements for Catnip?
Catnip requires a minimum of six hours of direct sunlight each day to thrive. Insufficient light can result in leggy growth and reduced flowering. A south-facing window is ideal for indoor Catnip, providing ample sunlight throughout the day. If natural light is limited, supplement with grow lights, positioning them about 6-12 inches above the plant. Rotate the plant regularly to ensure even light exposure on all sides. Monitor the leaves for signs of sunburn, such as scorched spots, if the light is too intense. Adjust placement or provide shade as needed. Adequate light is crucial for photosynthesis and overall plant health.
How do I care for Catnip?
Catnip thrives in well-draining soil and requires at least six hours of sunlight daily. Water thoroughly when the top inch of soil feels dry, but avoid overwatering to prevent root rot. Fertilize sparingly with a balanced, slow-release fertilizer in the spring to encourage healthy growth and blooming. Prune regularly to maintain a compact shape and promote bushier growth. Catnip is relatively low-maintenance but benefits from occasional deadheading to encourage further flowering. Protect from extreme cold during winter months, especially in colder climates. Indoor plants need good air circulation. Monitor for pests like aphids and spider mites, and treat promptly. Choose a pot with drainage holes.
How do I propagate Catnip?
Catnip can be easily propagated through stem cuttings, division, or seeds. For stem cuttings, take a 4-6 inch cutting from a healthy stem, remove the lower leaves, and place it in water or directly into moist soil. Roots should develop within a few weeks. For division, carefully dig up the plant and separate the root ball into smaller sections, ensuring each section has healthy roots and foliage. Replant the divisions in separate pots. Seeds can be sown directly into the garden or started indoors. Keep the soil moist until germination occurs. Propagation is best done in spring or early summer.
