This is an epiphytic sometimes lithophytic orchid, so Dendrobium gracilicaule grows naturally on trees or rocks.
Flowering from late winter into spring, the flowers themselves are yellow with a slight fragrance.
Care
This is naturally a plant that grows in filtered light, so similar conditions need to be provided. Actual growing conditions will vary according to climate and aspect, your local orchis club can provide expert advice.
- Where to Grow
You can grow Dendrobium gracilicaule as a mounted specimen, however many enthusiasts grow it in a slatted orchid basket which makes it a little easier to maintain. - Watering
Moisture from spring to autumn is required, winter can be a little drier. Mounted specimens will need regular watering, every day during dry conditions. In baskets, watering is required as the growing medium begins to dry.
The growing medium should never be allowed to become wet and soggy. In winter, Dendrobium gracilicaule requires a cool period with reduced water. - Fertiliser
A general-purpose orchid fertiliser at around 1/3 strength applied in spring to summer every two weeks should be adequate. - Repotting
These are an orchid that requires a restricted root run, so do not over-pot. The time to repot is immediately after flowering.
