I'm certainly not debating the level of difficulty of grafting. It's not something the average person can perform successfully without extensive research and practice.
The health of the scion will be directly proportional to the quantity of tissue correctly aligned, that being said, I'd speculate you'd have increasing success and scion health with more practice.
How many attempts did you make?
What style of grafts?
Any pictures?
I'm sure success rate would increase with practice. I've not counted attempts but it's more than 20 induvidual cuttings.
All were via a very acute "v" cut on the scion and a stalk split on the host. I tried rooting gel, aloe, and "dry". The sites were covered with teflon tape for the first attempts and I switched to "grafting" tape later. Scions were covered with plastic bags for the first week. All except one withered and or rotted.
Here's the graft site on the only successful graft I've taken (above the tag).
The actual scion (and host for that matter) look like shit right now as I've only been keeping the host alive until her clones root. They rooted a week or so ago and I've stopped watering completely. Tonight I'll cut it down and compost.
Grafting definitely works. I wouldn't bother using grafted plants to flower as the scion never looked as good as her cuttings. I could see it as a good method to keep genetics without using plant count. You'd need to be far more skilled than me and have a lot of time and patience.
Now please stop acting like an entitled douche. While you may not agree with many of the posters in this section the only things you're accomplishing is annoying everyone. Me included.
