Size of stock ---- rate of scion growth

What have people's experiences in regards to that? That is the height of a stock. What is the criterion of where to cut when grafting? I know it's best to use actively growing plants/cuts to graft on. Alright, so where do we cut? at the very tip?

But even more, lets say we graft on a non actively growing tip, lets say we graft on tip that has previously been damaged or cut. I suppose 10 cm are alright for hylocereus, as commercial plants come on such a stock...

My experience is very limited

People say 15-20 cm of Pereskiopsis is close to ideal.

What about Selinicereus, Hylocereus, myrtillocactus?

Is the best way to cut and bond in the fresh growing part, regardless of the height? Is the column width interrelating with how high to to cut when grafting?

Any thoughts? Thanks in advance

Hi Mutant,

I have done a few different experiments with regards to stock size. Pereskiopsis is an interesting one, longer and thicker stocks will promote faster scion growth but anything over 20cm will be too weak and will fall over or break under the weight of the scion. I usually take 20cm cuttings and bury 8-10cm in soil and await roots before grafting.

Cutting near the tip will give best results, just make sure you cut enough off or the stock will continue to grow and destroy your graft.

Good luck with your grafting.

hmmmmm what does this mean? That, say, if stock is too high it's going to pup all the time ignoring the stock f.e.? Because

'Cutting near the tip will give best results' & 'make sure you cut
enough off or the stock will continue to grow and destroy your graft' are contradictory, as 'near' the tip is pretty much a single area...

Giving some examples will be better. Will do when I am at home...

Sorry If I was unclear mutant. What I said does not really apply to Pereskiopsis because the apical meristem (growing tip) is quite small. However does apply to Columnar stocks such as Cereoids, Harrisia and even Hylo to some extent. If you cut such a small amount that you do not completely remove the growing tip then after a short period the tip will continue to grow and dislodge your graft.

Kada, in another post of his says you cut where the growing of the year has been done, showing you cut off all the fresh growth of the period.. So where is it, at the top, or depending also on the pupping tendency of the stock??

Because I have had extreme pupping problem with another lopho on myrti graft I did, the first graft I did actually

here they are..



awful looking I know! I am very curious to see what will happen in the forthcoming spring with these two! THey have been stalling for more than a year! Their story is similar to the other one. I stupidly hadn't beveled before the graft, so I beveled afterwards [remember this is my first grafts] but I left them uncovered and that night it rained! SO black rot, further cutting etc.. So this is a pretty stressed pair or pairs

I expect form them to do something to learn something more from them. Even abort the scions. Oh. I have cut off ALL of their areoles coz they drove me mad for several months constantly pupping. Oh. I also sunburnt them in the begining!

I've tried comparing the rate of growth with pachanoi stocks, I originally thought a taller one would cause the scion to grow faster, I tested two with loph caespitosa, so far the one on the short stock is growing much more rapidly forming a large clump however the one on the tall stock has formed a clump of heads all about the same size. I'm not sure if this has anything to do with the height of the stocks but it's just an observation. I tried testing it again with a browningia hertingliangana and a superkabuto asterias, the browningia was on a pach about 2 feet tall and the astro on one about half the height. So far the browningia isn't really growing that fast although they're pretty slow growers and I haven't grafted one before to compare. the astro has done absolutely nothing, I'm thinking I botched the graft and it's been sitting there in limbo, if it doesn't pick up soon I'm regrafting it. The stock is trying really hard to pup and it's swelling pretty badly, another sign it's a dud.
Also, first post

Welcome Sponge, thanks for the input mate.
