Intro
Dendrobium orchids are native to Southeast Asia, particularly in areas with warm and humid climates. They can be found in a variety of habitats, including the high altitudes of the Himalayas and the lowlands of tropical rainforests.
Diseases
Dendrobium orchids are susceptible to several diseases, including bacterial and fungal infections. Watch out for yellowing or withering leaves, black or brown spots on leaves, and a foul odor. Make sure to keep humidity levels in check, as excess moisture can promote disease.
Repotting
Dendrobium orchids should be repotted every 2-3 years, or when the potting medium becomes decomposed. Repot during the growing season, and use a well-draining potting mix that is high in bark content.
Fertilisation
Feed your dendrobium orchids during the growing season with a balanced orchid fertilizer, applied at half strength every 2-3 weeks. Cut back fertilizer during the winter months, when growth slows.
Positioning
Dendrobium orchids do best in bright, indirect light. In indoor settings, place them near a south or east-facing window. In outdoor settings, they can be placed in partial shade or dappled sunlight. Keep them away from direct sun, which can burn the leaves.
Watering
Dendrobium orchids require consistent watering to thrive. Indoor dendrobiums should be watered in the morning every week, allowing the soil to dry out between watering. Keep them away from excessive sunlight, which can dry out the soil faster.
Outdoor dendrobiums should be watered in the early morning or late afternoon two to three times a week, depending on weather conditions. Check the soil’s moisture level frequently. If the soil feels dry, the plants need water. Avoid overwatering as it can lead to root rot.
When watering, use room temperature water and aim for the roots and not the leaves or flowers. This helps prevent the growth of fungi and bacteria. Watering dendrobium orchids should be done with care; following this guide can help ensure a long and happy life for your plant.
Propagation
Dendrobium orchids can be propagated by division, stem or cane cuttings, or back bulbs. Make sure that each division or cutting has at least one healthy growing point, and plant in a well-draining potting mix.
Flower Colors
Dendrobium orchids come in a wide range of colors, including white, yellow, pink, purple, and bi-colored. Some varieties have striking patterns or markings on the petals.
