Grafting Cannabis. Multiple strains, one plant.

[MissinThe90’sStrains]

Have you noticed different rates of success for making grafts at different plant levels, or making grafts right after a recent pruning session ? Theoretically, hormones are re-allocated throughout the plant after breaking apical dominance and/or pruning, and my theory is that you can plan/time this to take advantage or create an “ideal” situation for the graft to take hold. I haven’t tried grafting yet, just reading and planning still.

Ive thought about the things that you mentioned. Documenting the rate of recovery for the grafts made at various levels of a plant is a worthwhile endeavor.

Basic plant biology would suggest that the top section of the plant would probably recover the quickest, since the majority of hormones are allocated to the terminal bud on a branch.

I wonder if a tongue graft would be more effective if its done to the tallest branch of the plant? I am definitely going to try that next.

Im going to purchase some grafting clips. Ive seen videos of this clip being used for rootstock grafts done to tomatoes. They come in many different sizes.

I checked the graft today, and I can actually see a small part of the scion begining to callous. Looks like the graft will be a success. Ive been spraying the plant with water once a day. It seems to be making a difference.



I decided to graft yet another scion. This time I will be attempting to graft a SSH in a similar fashion. The only difference is that im using a twist tie to really tighten things around the new graft.

Which would be better to use, soft or woody? I'm not very experienced on the topic but it seems that woody would increase the likelihood of success.

Sorry bud I only just seen this quote.

Generally green shoots root quicker imo they're favourable or maybe somewhere in between like where it's a bit turgid/firm.

Now that my mother plant has fully recovered from the previous graft, I decided to attempt something similar to a T Bud graft.
I took a cutting from one of the Malawi clones, and did my best to give it a good wedge so that it fits snug. This graft will be near the base of the plant. I took some extra measures to make sure its secured properly.


I also fed the mother plant today. Shes been starving for about a week.

I'm still trying to figure out how you did this bag trick? Lol, seriously, I can't figure it out.

Its plastic that I cut and tapped up. LOL

That's crazy, It looks like all you did was make holes for the branches.
I probably should have stubbed out my morning j half way.

You've gone the extra yard there

How is the graft doing today?

Unfortunately, the cutting of the MALAWI wilted. It wasn't going to make it. I think it was to soft and young. I removed it and replaced it with a more firm cutting.
If this new cutting doesn't make it, I will use rooting hormone on the next attempt. Im curious if that will help everything callous quicker.

Is it possible you got an embolism in the soft cutting?

Im not sure. When I removed the wilted cutting, I noticed that the open wound on the main stock was really dry. I think the mother plant is absorbing the water quickly. So, I might have to spray it down 2-3 times a day, just as a precaution. Or I could place the whole plant in a really big bag, I could try that next.

Your method on the first attempt looked sound. It's possible that you caught an embolism with the soft cutting, and/or the camdium of the rootstock was exposed to open air after the graft was made. I know you bagged it, but its possible the grafting point didn't remain moist.
I'm not very experienced in any of this, but I'm just thinking of possibles.

If you keep spraying that wilted graft it'll eventually catch on, without a plug is absolutely doable but sometimes require a lot of maintaining for the 1st couple of weeks.
You could trt putting some cotton wool or rock wool around the joint to supply water temporarily.

You could try cutting a shoot back to the lower nodes so when the fresh shoots grow it gives you fresh green growth connected to woody stem that's easier to work with?

Thats a good idea. Im going to pick up some cotton balls today.

Thanks for the tip about the lower nodes. Very useful information.

This is official attempt #3. I dipped the new cutting into rooting hormone, before inserting it into the mother plant. This time I will be using a plug again, since I now understand its purpose and importance.


The father plant seems to be doing just fine, and the scions are still alive and well. There isn't any visible progress on the grafts. I decided to dab some rooting hormone onto those grafts as well. Im curious if it will help speed up the callousing process.

I was trimming a plant today it's been vegged for ages and cut back numerous times, the repeated cutting back ime creates these little tiny shoots around the bottom that you might also see in late flower?

The pics poor but its those little tiny shoots low down I'm interested in.

This pic isn't much better but you can see the type shoot I'm on about at the very bottom of the stem.

I'm thinking a leather punch or maybe a (50 Cal) shell casing could be placed over them and pushed/twisted in to cut out the shoot out with like a disc of bark attached then you could put that disc into your new mum where you've a hole cut?

Idk but i think there's a reasonable chance of success with that?

That definitely seems plausible. The method your describing would create a perfect disk that can be easily inserted. Both plants would have to be a similar age, I think, otherwise the gauge of the disk will be different and that might cause the graft to fail because the cambium layers wouldn't line up.
