❓ Frequently Asked Questions — Comparing These Plants

Elder

What are the light requirements for Elder?

Elder trees thrive in bright, indirect light. While they can tolerate some direct morning sun, prolonged exposure to intense afternoon sun can scorch their delicate leaves. Place your indoor Elder near an east- or west-facing window where it will receive plenty of filtered sunlight. If you notice the leaves becoming pale or yellowing, it may be a sign that the plant is receiving too much direct light. Conversely, if the plant becomes leggy or the leaves lose their vibrancy, it may need more light. Supplement with a grow light if natural light is insufficient, especially during the darker winter months. Monitor the plant’s growth and adjust its placement as needed to ensure optimal light exposure.

How do I care for Elder?

Provide your indoor Elder tree with bright, indirect light. Too much direct sun can scorch the leaves. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Use a well-draining potting mix formulated for trees or shrubs. Maintain a stable environment, avoiding sudden temperature fluctuations and drafts. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune regularly to maintain shape and size, removing any dead or damaged branches. Repot every 1-2 years, or when the plant becomes root-bound, into a slightly larger pot. Check regularly for pests and treat promptly. Provide adequate humidity, especially during dry winter months, by misting the plant or using a humidifier. Ensure the pot has drainage holes. Rotate the plant periodically to ensure even growth.

How do I propagate Elder?

Elder can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem in spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in moist, well-draining potting mix. Cover with a plastic bag to create a humid environment and keep in bright, indirect light. Roots should develop in a few weeks. For air layering, wound a section of stem and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Keep the moss moist. Once roots have formed, cut the stem below the roots and plant in a pot. Ensure the pot is appropriately sized.

Flowering Kale

What are the light requirements for Flowering Kale?

Flowering Kale needs at least six hours of direct sunlight per day to develop its best color. Insufficient light can lead to leggy growth and dull coloration. When planting, choose a location that receives full sun exposure. If growing in containers, rotate the plants regularly to ensure even light exposure on all sides.

How do I care for Flowering Kale?

Flowering Kale thrives in cool temperatures (40-70°F) and requires at least 6 hours of sunlight daily. Plant in well-draining soil, enriched with compost or other organic matter. Water regularly, keeping the soil consistently moist but not waterlogged. Fertilize every 2-3 weeks with a balanced fertilizer during the growing season to promote vibrant color.

How do I propagate Flowering Kale?

Flowering Kale is primarily grown from seed, but propagation through stem cuttings is possible, though less common. Take stem cuttings from healthy, non-flowering shoots in late summer or early fall. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep the cuttings moist and in a warm, humid environment until roots develop.
