. I grafted a L. williamsii seedling to a Myrtillocactus geometrizans stock.I first cleaned the knife in hot water and used anti-bacteria soap, then rinsed the knife again in hot water.
Then I cut the growth point of my Myrtillocactus geometrizans off as cleanly as I could.
I then removed the roots of the L. williamsii.
After that I put them together so that the vascular bands were touching.
Then I "sealed the deal" with a plastic bag and an elastic band.
It is now upstairs in the warmth of my room to promote growth and getting plenty of light on my windowsill. Have I done everything right and how long does it usually take for grafts to take?
Here are some pics:
You'll know within 2 weeks whether it's taken or not. They can be slow to start growing at first, though. My latest graft on Epiphyllum hasn't done much growth, but the scion has been fattened up quite a lot.
