Cinnamon
Cinnamomum verum
Cinnamon (Cinnamomum verum) is a beloved spice known for its aromatic bark and culinary uses. Native to Sri Lanka, it thrives in warm, humid environments, making it a delightful addition to gardens and homes. People grow it not only for its flavor but also for its attractive foliage and potential health benefits.
Everything it needs
9 essentials at a glance
Watering
Cinnamon prefers consistently moist soil but should not be waterlogged.
Water every 1-2 weeks, allowing the top inch of soil to dry out between waterings. In the winter, reduce watering frequency to once every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaf drop and wilting.
Light
Cinnamon thrives in full sun to partial shade, ideally receiving 6-8 hours of direct sunlight daily.
It can tolerate some shade but may grow slower in lower light conditions. Ensure it is placed in a bright spot, as insufficient light can lead to leggy growth.
Soil
Cinnamon prefers well-draining, loamy soil with a pH range of 6.0 to 7.0.
A mix of potting soil, perlite, and compost is recommended to ensure good drainage. Avoid heavy clay soils that retain too much moisture.
Humidity
Cinnamon thrives in high humidity levels of 60% or more.
To increase humidity, consider misting the leaves regularly or placing a humidifier nearby. Signs of humidity stress include browning leaf tips and edges.
Temperature
Cinnamon prefers temperatures between 65-80°F (18-27°C) and is hardy in zones 10-12.
It is sensitive to cold and should be protected from temperatures below 50°F (10°C). During winter, ensure it is kept in a warm environment.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10 or similar.
Fertilize every 4-6 weeks during the growing season (spring and summer) and reduce to once every 8-12 weeks in fall and winter. Signs of nutrient deficiency include yellowing leaves, poor growth, and leaf drop.
Pruning
Prune cinnamon plants in late winter or early spring to encourage bushier growth and remove any dead or damaged branches.
Use clean, sharp pruning shears to make clean cuts. Regularly pinch back new growth to promote a fuller shape and enhance leaf production.
Repotting
Repot cinnamon every 2-3 years or when it becomes root-bound.
Choose a pot that is 1-2 inches larger in diameter than the current one. Signs it needs repotting include roots growing out of the drainage holes and slowed growth. To repot, gently remove the plant from its pot, loosen any tightly bound roots, and place it in fresh potting mix.
Propagation
Cinnamon can be propagated through stem cuttings or seeds.
For stem cuttings, take 6-8 inch cuttings from healthy stems, remove lower leaves, and place them in a moist potting mix. Keep the cuttings in a warm, humid environment until roots develop, which usually takes 4-6 weeks. For seeds, sow them in a well-draining mix and keep them warm and moist until germination.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or nutrient deficiency.
How to fix it
Check soil moisture levels and adjust watering frequency. Fertilize with a balanced fertilizer if nutrient deficiency is suspected.
Browning leaf tips
Why it happens
Low humidity or underwatering.
How to fix it
Increase humidity around the plant by misting or using a humidifier, and ensure consistent watering.
Leaf drop
Why it happens
Sudden temperature changes or stress.
How to fix it
Keep the plant in a stable environment away from drafts and sudden temperature fluctuations.
Root rot
Why it happens
Over-watering and poor drainage.
How to fix it
Allow the soil to dry out and improve drainage. If severe, repot the plant in fresh soil.
Pest infestations (e.g., spider mites)
Why it happens
Dry conditions or poor air circulation.
How to fix it
Increase humidity and ensure good air circulation. Treat with insecticidal soap if necessary.
Care through the year
Spring
In spring, increase watering as the plant begins to actively grow. Fertilize every 4-6 weeks to support new growth.
Summer
During summer, ensure the plant receives plenty of sunlight and maintain humidity levels. Water regularly, especially in hot weather.
Fall
In fall, gradually reduce watering frequency and fertilization as the plant prepares for dormancy. Monitor for pests.
Winter
In winter, keep the plant in a warm location and reduce watering to every 2-3 weeks. Avoid cold drafts and ensure adequate light.
Toxicity & Safety
Cinnamon is generally safe for pets and children, but excessive ingestion can cause gastrointestinal upset. The bark and leaves are safe, but essential oils should be kept out of reach of pets.
