Anoectochilus koshunensis

[Maria]

Anyone else growing this jewel orchid? Two of the leaves near the top of the plant have turned reddy-orange. The plant was growing in a low light area, rain water only, lots of humidity. Help

For those who are attempting Anoectochilus species. This is an easy genus of terrestrial orchids to grow. Almost like Ludisia. But unlike Ludisia which can handle lots of abuse and come back smiling, Anoectochilus needs a soil mix that drains FREELY. In fact you can let it dry out as long as your humidity levels approach 80% or higher. I currently have the two I am growing in a plastic box to protect them from further slug damage. They need a fairly constant range of warmth which most vivs or terrariums can provide, prob. in the high 70s to mid 80s would be ideal even though in my greenhouse it drops down to the mid 60's. Keep in mind that the lower leaves will die off-this is normal. If the top leaves start changing color and wilting back it is NOT NORMAL. Something is wrong and in most cases the roots are sufferring or the plant is being kept too cold. To recap:
1. Water only when dry.
2. Maintain humidity at 80%
3. Keep warmth constant range 76F-88F
4. Use rapidly draining substrate, such as fine bark with sphagnum fibers mixed together and either perlite or styrafoam chips.
5. Provide at least 800 ft candles illumination.
