Dendrobium gracilicaule

This is an epiphytic sometimes lithophytic orchid, so Dendrobium gracilicaule grows naturally on trees or rocks.

Found growing in the foothills of eastern Australia from Northern New South Wales to Cape York, Dendrobium gracilicaule is a relatively easy care species with fragrant flowers.

In the natural environment it grows at elevations to 600 metres it is classed as a cool to warm growing species.

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.

Mostly grown in containers, as well as mounted specimens container growing seems the easiest method.

A free draining growing medium is essential, moisture and some humidity are required. Try a mixture of pine bark and sphagnum moss for good results.

Best grown with restricted root space, over time it will form a large clump of canes and eventually need repotting.

1. 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.
2. 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, this orchid requires a cool period with reduced water.
3. Fertiliser
   A general-purpose orchid fertiliser at around 1/3 strength applied in spring to summer every two weeks should be adequate.
4. Repotting
   These are an orchid that requires a restricted root run, so do not over-pot. The time to repot is immediately after flowering.
