❓ Frequently Asked Questions — Comparing These Plants

Crown of Thorns

What are the light requirements for Crown of Thorns?

Crown of Thorns requires bright, direct sunlight to thrive. Ideally, place it in a south-facing window where it can receive at least 4-6 hours of sunlight per day. Insufficient light can lead to leggy growth, reduced flowering, and a loss of vibrancy in the bracts. If you don’t have a sufficiently sunny window, consider supplementing with a grow light. Rotate the plant regularly to ensure even light exposure on all sides. During the summer months, you can move your Crown of Thorns outdoors to a sunny location, but be sure to acclimate it gradually to avoid sunburn. The plant’s ability to flower profusely depends on adequate light.

How do I care for Crown of Thorns?

Crown of Thorns thrives on neglect, making it an easy-care succulent. Plant it in well-draining soil, such as a cactus mix, to prevent root rot. Provide it with bright, direct sunlight for at least 4-6 hours daily. Water sparingly, allowing the soil to dry completely between waterings. Reduce watering frequency during the dormant winter months. Fertilize lightly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Maintain a room temperature between 65-75°F (18-24°C). Avoid overwatering, as this is the most common cause of problems. Repot every 2-3 years, or when the plant becomes root-bound. Prune to maintain shape and remove dead or damaged stems. Be cautious of the milky sap, which can be irritating to the skin and eyes.

How do I propagate Crown of Thorns?

Crown of Thorns can be propagated through stem cuttings. Allow the cut end to callous over for several days before planting in well-draining soil. Keep the soil slightly moist until roots develop. Leaf cuttings are not generally successful. Offsets, or small plantlets that grow at the base of the plant, can be carefully separated and potted individually. Wear gloves to protect your skin from the irritating sap. Rooting hormone can improve the success rate of stem cuttings. Provide bright, indirect light during the rooting process. Avoid overwatering, as this can lead to rot. Propagation is best done during the growing season (spring and summer).

Fragrant Sumac

What are the light requirements for Fragrant Sumac?

Fragrant Sumac as an indoor tree requires bright, indirect light to thrive. Insufficient light can lead to leggy growth and reduced foliage density. Place your plant near an east- or west-facing window where it can receive several hours of filtered sunlight each day.
