So eventually I got to repot this Bougie. I had forgotten that I had a cascade pot hidden in my cupboard and only after a tidy up did I realise that I could use it. Now it might not be the final pot that I want it in but it at least now over the next few seasons, I can develop the canopy in a cascade position. It also allows me the time to look at my leisure until I find the perfect pot.
I had to take off quite a few roots to fit it into the pot so I defoliated it at the same time to give it as much chance to recover quickly. I am not too worried as it has been fertilized like crazy ever since I got it and it is growing like a weed.
