I have recently purchased a cattleya dowiniana aurea.
This morning I noticed new root growth on the largest
pseudobulb. It is in a plastic pot and I would like to
repot into a basket.Is this a good time or should I
wait till early spring.
If you are sure that you have new root growth, go for it! All 3 of my dowianas (2 large seedlings and 1 NBS) are in baskets and they seem to really like it.
