Does anyone know how to divide ground orchids? Years ago I bought one small plant and planted it in the ground, now it's grown into a huge clump, I have tried dividing it, but the plants I separate from the group always die. They have rhizomes and I try to make sure each plant I separate has a fairly large rhizome and lots of buds but it dries up in a few days after I transplant it. Here's what they look like:  |

They are lovely. I think you might be dividing them at the wrong time, you say they have buds which mean they are actively growing. Most orchids will have a dormant period when they are not growing, this would be the best time to split them.

I found this on the web, it might be useful
Spathoglottis Plicata
Care must be taken when (trans)planting them. Soils which are high in organic content almost always cause trouble in combination with orchids. In this species it's the pseudobulb that is prone to rot, never bury it too deep in its substrate. Fill the spot where you want to plant them until 5 cm [2”] below the desired surface level, plant the pseudobulbs and add the remaining amount of substrate. The pull the pseudobulbs up while filling the cavity below it: push soil between the roots and under the pseudobulb with your fingers. When you're finished the pseudobulbs should have only it's bottom 1 cm [1/2”] buried. Small bulbs should be at least 3/4 above soil.
