Here's another veiw of our Dendrobium speciosum repot. Never again.

I have some worse for wear 200mm pots (approx 8) Dendrobium speciosum that need repotting. I am going to attempt to place them on a merbau platform that will hang on a large solid brick pillar facing North East. Problem is they have to survive coming from the Hawkesbury to Goulburn. Am I dreaming? When would the best time to do this be? Presently they’re sheltered outside among other trees/shrubs waiting to be planted out in a paddock. Cheers, thank you.
