In a T budding technique of grafting fruit trees, how does the cambium layer of the bud come into contact with the cambium layer of the rootstock?

How does this great method have such a high success rate if there is no direct contact between the cambium layers?

The upside down T method is usually more recommended.

Here is a great video that demonstrates this method.

This is the photo that I made that shows where I think there is contact between the cambium layers, let me know if I am correct or not:

There is direct contact between the two cambium layers - the removed bud has cambium (meristematic tissue) exposed on the cut side, and the T cut made in the stem it's to be grafted to has the bark or exterior tissue peeled back to reveal the cambium prior to insertion of the bud, as clearly demonstrated in the video you linked with. Whether the T cut in the rootstock stem is upside down or right side up, the principle is still the same.

In the UK, T budding is generally used on roses, and that's the only time I ever came across this method - trees are more often chip budded. In the case of roses, its usual to remove woody material from the back of the bud prior to inserting into the T shape on the rootstock.

  • So where is the contact, on the sides or on the top-bottom? – csandreas1 Nov 17 '17 at 21:00
  • all the way up - if you watch your video, you can see the exposed meristematic tissue on the bud where its been cut, and you see the bark being folded back to reveal the cambium on the stem of the rootstock, prior to insertion – Bamboo Nov 17 '17 at 21:29
  • I made a photo with the red lines showing the contact of the cambium layers, let me know if it is correct https://i.imgur.com/3tDRszh.jpg – csandreas1 Nov 17 '17 at 21:30
  • Yea, looks about right, though obviously, I can't see the cut bud you made as its already inserted; but its a little confusing, that image - usually, the peeled back bark is folded back over after insertion, then taped, I'm not seeing any bark folded back over, did you peel the bark back on the rootstock stem round the T cut? – Bamboo Nov 17 '17 at 21:33
  • look in my website my gallery: https://www.mpoliasma.top/page3.php the photo was taken 1 month after grafting – csandreas1 Nov 17 '17 at 21:35
  • Oh right, I see - and the other pic is when you first did it, presumably... that bud (2nd photo) looks healthy and swollen...which is good – Bamboo Nov 17 '17 at 21:38
  • yeah, as i remember i left some wood on the bud. It is second year since i grafted that and it has around 10 lemons. It has grapefruit, lemon and orange on it. The first and second photos are like 1-2 months after grafting – csandreas1 Nov 17 '17 at 21:40
  • So it worked then...! – Bamboo Nov 17 '17 at 21:58
  • i grafted today, by looking at the photos with the grafts and temperature what do you believe is the chance for success? https://imgur.com/a/YwjjF – csandreas1 Nov 18 '17 at 10:35
  • One can never know - looks good in the photo, but if you're in the northern hemisphere, its a bit late in the season, depends where you are. These things are always a wait and see anyway – Bamboo Nov 18 '17 at 10:46
  • Click the link i posted before, there is a photo with the temperature of my area – csandreas1 Nov 18 '17 at 10:47
