Thanks for all the responces.
As the area I currently have the trays in is very shaded and sometimes
can become wet I will move them into an area of the greenhouse that is
fairly cool and relatively light.

Hopefully I'll be able to give you a positive update in another six
months!

In 6 months they won't have any leaves and will be dormant. :-)
