My first Dendrobium

[estación seca]

Translating to Portland, as warm as you can keep it. High humidity. Don't let it dry out very long. As much winter sun as possible, but be careful in the spring that the small seedling doesn't sunburn after the long, dark winter. It should eventually do great outside during the summer, and you can probably gradually move it into full sun as spring progresses once it's much bigger. Next spring move it gradually into dappled shade. Fertilize a lot when in growth.
