Jenkins' Dendrobium

Jenkins' Dendrobium key facts

Growing Difficulty

Intermediate

Lifespan

Perennial that can be kept for many years as it clumps up (little data on lifespan)

Size

Miniature; flowers about 3 cm across

Watering

Dilute liquid fertilizer in the growing season

Light & Placement

It likes bright light, especially full light in winter; lightly shade only from harsh midsummer sun.

Watering

Mounted plants dry quickly, so water often while growing; in winter water sparingly and keep it dry.

Temperature & Overwintering

It prefers intermediate to slightly cool conditions; bring it indoors in winter and keep it from frost.

Soil & Repotting

Dormancy Care

A dry winter rest helps it flower well in early spring.

About Jenkins' Dendrobium

Dendrobium jenkinsii is an extremely miniature epiphytic orchid grown mounted on cork, producing honey-scented yellow flowers in early spring. Best suited to growers with some orchid experience.

7 things to know before growing Jenkins' Dendrobium

1. 1Light and Placement

   Dendrobium jenkinsii likes bright light, and giving it plenty of sun in winter in particular helps it flower in early spring. Provide light shade only during the strongest midsummer sun. Good air circulation also helps keep the roots and pseudobulbs healthy.

2. 2Watering

   Because the plant is mounted on cork rather than potted in soil, it dries out quickly. During the spring-to-autumn growing season, water thoroughly (or mist frequently) once the mount has dried. In winter, growth slows, so cut back on watering and keep the plant slightly on the dry side to encourage flower buds to form.

3. 3Growing on a Cork Mount

   As an epiphyte that grows with its roots exposed to the air, this orchid is sold and grown mounted on cork or a piece of wood rather than planted in soil. Roots that stay damp for too long are prone to rot, so make sure the mount dries out well in a well-ventilated spot after watering.

4. 4Remounting

   When the cork mount deteriorates or the plant outgrows it, it's time to move the orchid onto a new mount. The best window is right after flowering, before the roots become active and new growth begins.

5. 5Seasonal Temperature Care

   This orchid enjoys warm conditions during its growing season, but a cooler, drier rest period in winter helps trigger flowering the following spring. Protect it from cold drafts and frost while still allowing it to experience cool, relatively dry conditions.

6. 6Choosing a Healthy Plant

   Look for plants with plump, firm pseudobulbs and roots that are well attached to the mount. Leaves without dark spots or wrinkling, along with several pseudobulbs clustered together, are signs of a healthy, well-established plant.

7. 7Growth and Division

   The pseudobulbs multiply gradually into a clustering clump, so the plant can be enjoyed and grown for many years. Once it has filled out, it can also be divided during its active growing season to produce additional plants.

Frequently asked questions about Jenkins' Dendrobium

Q.Is this orchid suitable for beginners?

A.Dendrobium jenkinsii is generally considered suitable for growers with some orchid experience rather than complete beginners. Its epiphytic watering needs and seasonal care require a bit of a learning curve, so prior experience with other orchids helps.

Q.When does it bloom, and what does it smell like?

A.It blooms in early spring, producing one to five bright yellow flowers from the side of a single thick leaf. The flowers carry a sweet, honey-like fragrance that can be enjoyed up close during the blooming period.

Q.How large does this plant get?

A.It's an extremely miniature Dendrobium, with flowers around 3 cm across. The pseudobulbs themselves stay small too, making it an easy size to fit into a compact growing space.

Q.How often should I water it?

A.Because it's mounted on cork, it dries out quickly, so during the spring-to-autumn growing season you'll need to water or mist it frequently whenever the mount dries. In winter, growth slows and the plant should be kept a bit drier.

Q.How long can this plant be grown?

A.It's a perennial plant that can be grown for many years as its pseudobulbs gradually multiply. Detailed data on its overall lifespan is limited, but with periodic division, the plant can be kept going and passed on for a long time.
