It seems that dividing Dendrobium speciosums in Febuary is just fine and dandy!
Im always a stickler for routine and habitual in the way I repot and divide
I have always repoted and divided my speciosums in October as the first growth of the season starts to form its toothbrush of new roots.
THis year we repotted non stop from August until mid march. We always pot the smallest plants first up to the largest.
The speciosums had not been divided for 3 years so they could only be slotted in for febuary through march
It took 7 of us 6 weeks to complete, but all done and dusted 4 weeks ago.
Some where potted into the slots cut in the long dead Cyatha tree fern pots we had made
The results are clear! So Febuary dividing and repotting is fine!
