New Den farmeri and thyrsiflorum questions

[Fairorchids]

There is a world of a difference between:

• Normal watering
• Drier in winter
• Winter rest

In this Dendrobium section (densiflorum), I would suggest only a slight reduction in watering (& fertilizer) from late Nov through early March or so.

For Den kingianum, speciosum & Den nobile, I cut back watering 90% from mid Oct till buds are well formed (and zero fertilizer from Sept 15 till buds open).
