Cedar vs Oat Grass Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Cedar
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.
Oat Grass
Avena sativa
Avena sativa, or oat grass, is an annual cereal grain. It's characterized by its slender, upright stems and long, narrow leaves. Primarily grown outdoors for grain production, it's also cultivated as a cover crop and animal fodder. While sometimes grown indoors for pets, it's not naturally an indoor plant and requires specific conditions to thrive. People grow it for its nutritional value, as a pet treat, or for its aesthetic appeal as a temporary green addition.

💡 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.
Oat Grass Care Tips
Oat grass is primarily an outdoor plant. Growing it indoors requires ample sunlight, proper watering, and good ventilation. It's best suited as a temporary indoor plant, as it may not thrive long-term without ideal outdoor conditions. Expect a shorter lifespan indoors.
- Ensure excellent drainage to prevent root rot.
- Provide supplemental lighting if natural sunlight is insufficient.
- Rotate the pot regularly to ensure even growth.
- Avoid overcrowding the seeds when planting.
- Monitor for pests and diseases regularly.

❓ 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.
Oat Grass
What are the light requirements for Oat Grass?
Oat Grass flourishes in bright, indirect light. Insufficient light can lead to leggy growth and reduced flowering. An east-facing window is often ideal, providing gentle morning sun. A west-facing window can also work, but be cautious of intense afternoon sun, which can scorch the leaves. If you only have south-facing windows, filter the light with a sheer curtain.
How do I care for Oat Grass?
Oat Grass thrives in bright, indirect light. Direct sunlight can scorch its leaves. Water thoroughly when the top inch of soil feels dry to the touch, ensuring good drainage to prevent root rot. Use a well-draining potting mix. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Maintain a moderate humidity level, ideally between 40-60%.
How do I propagate Oat Grass?
Oat Grass can be propagated by division. In spring, carefully remove the plant from its pot and gently separate the root ball into smaller clumps, ensuring each clump has healthy roots and foliage. Replant each clump in its own pot with fresh, well-draining potting mix. Water thoroughly and keep in a bright, indirect light location.
