here is the grafting i did 3 weeks ago , does anyone know how long will it take to show some signs of success,
or by looking at these photos , can you tell me if it's dying ?
I used teflon tape and some grafting paste on top of it.
Half of the cuttings looks dry

And one more question, let's say that it did not took it, do i rip it out or just leave it alone?
would it damage the tree?

What kind of joint/cut did you use for your graft?

I look forward to hearing the answer to your questions as I have a similiar project underway.

I use very small pieces to graft - although I put some larger ones on my tree last fall. they have been sleeping ever since, no signs of life or death.. 3 weeks is too early to tell. I'd think the cutting is heavy for that joint, and could force the joint to open. Grafting is fun to experiment.. you have to try many times - as Harvey said, failure is when you don't try.

The scion wood should be protected from drying out. Using grafting tape, grafting sealer or grafting wax. If not properly protected the scion will desiccate before the graft can heal (take).
Good Luck.

I had a gorgeous Madeleine deux Saisons with 2 sets of leaves and was taking off beautifully (graft) then, yesterday someone decided that it was hot and it needed water... I found the graft hanging by a thread and obviously broken/dead.. I was so mad and still am.. Even water from a hose can break them they are so fragile and specially grafts break easily... so, all I could do, is trim it again and I cut all leaves but one in half and grafted it to my tree soon I discovered the accident...to my surprise, the half leaf has perked up today and I may be lucky that it will live on my tree.
here it is where it was living happily and where it is now (the only leaf I left on to help it heal...

Wow, Grasa... I feel sorry for the little guy, wish him well!
How long does it take before the union is strong?

I am not sure how long, but I read a lot about grafts need support or branches break from their own weight... so I am planing here. I have another italian that I grafted on a heavy cutting (Anemone) has taken off and it is so strong, I am afraid it will break, so I am thinking of what do to to support that one. I am new at this, so there is a lot of trying...

This is the grafting method I used last year ( thanks to Nelson for showing me ) and 12 out of 12 grafts were successful and are now budding .

I would cover the scion with white paper or foil to reduce direct sunlight which can cook the scion or dry it out.

Doesn't matter if it takes 3 weeks or 3 months. Be patient and just let it be. Even if the graft is successful, with the cambium layers growing together, it will still need a couple years growth to develop real strength. Only the cambium grows together - all the wood in the center of the cutting never grows together.
