How do I get my dendrobium orchid to bloom again?
A Dendrobium Nobile will rebloom yearly when a reduction of 20 to 30% in water has occurred, temperatures have dropped to 55° F or 13° C during fall and winter, and when potassium levels are increased.
When should I water my dendrobium orchid?
Dendrobium orchids can store water and are more tolerant of dry soil than overly wet soil. Water them every 1-2 weeks. Allow the top 1 inch (2.5 cm) of the soil to dry before re-watering. Some species of dendrobium orchids have water-storing pseudobulbs, meaning they can go 2 weeks between waterings.
Should I cut dendrobium stem?
In dendrobium orchids, the pseudobulb is the long, narrow slightly fleshy lower half of the stem that produces the plant’s leaves and often has rings around its bottom half — scars from dropped leaves — making it resemble cane. This structure stores water for the plant and should not be cut.
How do you care for dendrobium after flowering?
Once blooming has finished, increase watering, begin regular fertilizing, keep it in temperatures of between 65-85 °F (18-30°C) and ensure it gets plenty of bright light to maximize vegetative growth.
How do you force a Dendrobium to bloom?

Is Dendrobium speciosum an orchid?

As a general rule: 10mm grade up to 100mm pots, 15mm for all else up to 200mm with 20mm or 25mm for larger pots and Den speciosum from 150mm upwards. Seedlings in 50mm pots should be potted up with finer grade seedling bark. The old adage of weekly-weakly applies to cooler to intermediate growing Australian native dendrobiums.
