Dendrobium Orchids - mature plants
Our Dendrobiums are in excellent condition.
These older orchids are planted in 6" pots
We grow them in gravel to reduce root disease and to facilitate drainage.
Dendrobium grows best in bright light but may sunburn if left in full mid-day sun - give them a bit of protection during this time of day and keep them pretty dry to reduce disease.
We water when the gravel in the middle of the pot is dry - you can tell as it would be the same color as the gravel on the top layer of the pot.
Once the roots start "jumping" out of the pot it is time to move them to a slightly larger pot - not too large, however - we generally recommend 2" larger - so 4" to 6", 6" to "8" etc. If you are purchasing a 6" pot you should not have to repot it for approximately 1 year unless the roots are already growing out of the pot. Use the red gravel people use to make concrete for your potting mix. We strongly recommend that you do NOT use Bark, Coconut, Charcoal, or other materials that will break down over time. This process creates bacteria around the roots which can be deadly.
