Dendrobium Orchid Care

Dendrobium orchids are a diverse and beautiful group of orchids known for their striking appearance and vibrant blooms. With the right care, they can thrive and reward you with gorgeous flowers.

This sheet will help you grow healthy Dendrobium orchids:

Light Requirements:

Dendrobium orchids thrive in bright, indirect light. They should receive filtered sunlight, such as through a sheer curtain or by placing them near a window with
bright, indirect sunlight. Avoid direct afternoon sun, which can scorch the leaves.

Temperature:

Dendrobiums typically prefer warm to intermediate temperatures. Daytime temperatures between 65-85°F (18-30°C) and nighttime temperatures around 55-65°F (13-18°C) are generally ideal. Provide good airflow to prevent
temperature extremes.

Humidity:

These orchids appreciate higher humidity levels, around 50-70%. If your home is dry, use a humidity tray or a humidifier to maintain adequate moisture in the air.

Watering:

Dendrobiums prefer to dry out slightly between waterings. Water them when the top inch of the potting medium feels dry. Be cautious not to overwater, as this can lead to root rot. Water thoroughly, allowing excess water to drain from the pot.

Potting Medium:

Use a well-draining orchid mix consisting of materials like bark, sphagnum moss, or coconut husk. Report your Dendrobium orchid every 1-2 years or when you notice overcrowding in the pot.

Fertilization:

Feed your Dendrobium orchid with a balanced, water-soluble orchid fertilizer during the growing season (spring and summer). Dilute the fertilizer to half the
recommended strength and apply every 2-4 weeks. Reduce or stop fertilization during the dormant period in fall and winter.

Dormancy:

Some Dendrobium orchids go through a natural dormancy period in the cooler months. During this time, reduce watering and cease fertilisation until new growth emerges.

Pruning:

Trim back spent flower spikes after the blooms have faded, cutting just above a node. This encourages the orchid to produce new flowers.

Pest and Disease Control:

Keep an eye out for common orchid pests like scale, mealybugs, and aphids. If you notice any infestations, treat your orchid promptly with insecticidal soap or neem oil. Ensure good air circulation to prevent fungal issues.

Support and Staking:

Many Dendrobium orchids have long, arching canes that can become top-heavy. Use stakes or supports to help the plant maintain an upright position and prevent damage to the canes.

Repotting:

When repotting, choose a slightly larger pot if necessary and ensure good drainage. Be gentle with the orchid’s roots, as they are delicate.

Blooming:

Dendrobiums typically bloom once a year, with some varieties producing multiple blooms on the same cane. Proper care, including adequate light, temperature, and fertilization, can encourage blooming.

By following these care guidelines, you can enjoy the beauty of Dendrobium orchids and watch them flourish in your home. Remember that specific care requirements may vary slightly depending on the exact Dendrobium species or hybrid you are growing, so it’s a good idea to research the specific needs of your orchid variety.

Happy orchid growing.
