Hi, i grafted a pup onto pereskiopsis, it was successful, but lately the orange stuff started to spread out around the base, and grafted pup was not growing. Each day it looked worse, pup was soft, so I removed the pup, and this yellow dry tissue was underneath the cutting line. Why can it happen? I kept it under a clear bag to keep humidity. Maybe I kept it humid for too long? When can remove the bag, after a week maybe?

I see that on all of mine, but I have < 15 under my belt now. It seems to be normal to have that around the graft.
If there’s orange UNDER the graft, it was not a good seal. I’d think it might have been due to dryness. The Peres should be watered leading up to the graft, and not again till at least a week after (maybe more if they will manage it). I also see folks squeezing a leaf into the graft area right before setting the Scion to add more “juice”.
This happened to me with the same pup twice in a row, the same rusty brown. I thought that it may be bad surface tension between the scion or stock due to an imperfection in the cut made on either. Once I focused on making the straightest, cleanest cut I could it worked fine. On the attempt that worked, the scion was stuck almost vaccumed to the stock due to the perfect surface tension and connection. Make sure when you place the scion onto the stock, there is some pereskiopsis juice but not too much that it pushes the scion off – I usually water around 3-4 days before I graft. After you place the scion, press it firmly onto the pereskiopsis to push any air bubbles out.
If there is not good surface tension or a lack of contact between both plants they may not union, causing the fungal issues you see.
