Cedrus spp.

Cedrus species, commonly known as true cedars, are coniferous evergreen trees characterized by their aromatic wood, needle-like leaves arranged in spirals on long shoots and in dense clusters on short shoots, and barrel-shaped cones. They are large trees, typically reaching heights of 30-40 meters (100-130 feet) or more in their native habitats. Cedars are primarily outdoor trees, valued for their majestic appearance and use in landscaping. They are not naturally indoor plants and struggle to thrive in the confined conditions of indoor environments. People grow them for ornamental purposes, timber production, and their cultural significance.

💡 Pro Tips For Comparing These Plants

Cedar Care Tips

Cedars are primarily outdoor trees and are extremely challenging to grow indoors. They require full sun, well-draining soil, and proper humidity levels, which are difficult to replicate indoors. Indoor cultivation is generally not recommended.

  • Ensure proper drainage to prevent root rot
  • Water deeply but infrequently, allowing the soil to dry out slightly between waterings
  • Protect young trees from harsh winter winds and frost
  • Monitor for pests and diseases regularly
  • Prune annually to remove dead or damaged branches and maintain shape.
❄️ Winter: Protect young trees from frost and harsh winter winds. Mulch around the base of the tree to insulate the roots. Reduce watering during dormancy.
☀️ Summer: Ensure adequate watering during dry periods. Monitor for pests and diseases. Provide shade for young trees during the hottest part of the day.

New Guinea Impatiens Care Tips

New Guinea Impatiens require bright, indirect light and consistent moisture. They are susceptible to root rot if overwatered. While they can be grown indoors, providing adequate light can be challenging. Regular fertilization promotes abundant blooms. Watch for pests like aphids and spider mites.

  • Provide bright, indirect light to encourage blooming.
  • Water thoroughly when the top inch of soil is dry, but avoid overwatering.
  • Fertilize regularly during the growing season with a balanced liquid fertilizer.
  • Pinch back stems to promote bushier growth.
  • Monitor for pests like aphids and spider mites and treat promptly.
❄️ Winter: Reduce watering frequency and stop fertilizing during the winter months. Provide bright, indirect light and maintain a temperature above 15°C. Protect from drafts.
☀️ Summer: Provide consistent moisture and fertilize regularly during the summer months. Protect from direct sunlight, especially during the hottest part of the day. Increase humidity if possible.

❓ Frequently Asked Questions — Comparing These Plants

Cedar

What are the light requirements for Cedar?

Indoor cedars thrive in bright, indirect light. Placing them near an east- or west-facing window is usually ideal. Avoid direct sunlight, especially during the hottest part of the day, as it can burn the delicate needles. Insufficient light can lead to leggy growth and yellowing foliage. If you don’t have access to sufficient natural light, consider supplementing with a grow light. Rotate your cedar regularly to ensure all sides receive adequate light. During the winter months, when sunlight is less intense, you may need to move your cedar closer to a window or increase the amount of supplemental light. Pay close attention to the plant’s growth and adjust its position accordingly.

How do I care for Cedar?

Indoor cedar trees require bright, indirect light; avoid direct sunlight, which can scorch the foliage. 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 conifers or evergreens. Maintain moderate humidity, especially during dry winter months. Fertilize sparingly, only during the growing season (spring and summer), with a balanced liquid fertilizer diluted to half strength. Prune regularly to maintain the desired shape and remove any dead or yellowing foliage. Repot every 2-3 years, or when the plant becomes root-bound, into a slightly larger pot. Ensure adequate air circulation to prevent fungal diseases. Monitor for pests such as spider mites or scale and treat promptly. Provide stable temperatures, avoiding drastic fluctuations. Rotate the plant regularly to ensure even growth on all sides.

How do I propagate Cedar?

Cedar can be propagated through stem cuttings or air layering. For stem cuttings, take 4-6 inch cuttings from new growth in spring or early summer. Remove the lower needles and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it moist and humid. Rooting can take several weeks to months. For air layering, make a small incision in a branch, apply rooting hormone, and wrap the incision with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Once roots have formed, cut the branch below the roots and pot it up. Both methods require patience and careful monitoring. Maintain consistent moisture and humidity for successful propagation. Choose healthy, vigorous branches for the best results.

New Guinea Impatiens

What are the light requirements for New Guinea Impatiens?

New Guinea Impatiens prefer bright, indirect light. They thrive in partial shade, making them ideal for locations that receive morning sun and afternoon shade, or dappled sunlight throughout the day. Direct sunlight can scorch their leaves and fade their flowers, so avoid placing them in areas with intense, prolonged sun exposure.

How do I care for New Guinea Impatiens?

New Guinea Impatiens thrive in partial shade with consistent moisture. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Fertilize regularly during the growing season (spring to fall) with a balanced, water-soluble fertilizer, or one formulated for blooming plants, diluted to half strength, every 2-4 weeks to encourage abundant blooms. Maintain a humid environment by misting the plant regularly or placing it near a humidifier.

How do I propagate New Guinea Impatiens?

New Guinea Impatiens are easily propagated through stem cuttings. Take a 4-6 inch cutting from a healthy stem, removing the lower leaves. Dip the cut end in rooting hormone and plant it in a well-draining potting mix. Keep the soil moist and provide bright, indirect light. Roots should develop within a few weeks. Division is possible when repotting larger plants, carefully separating the root ball. Keiki propagation is not applicable to New Guinea Impatiens.
