Trying out doing Cereus seedling grafts using seedlings only a few days after germination.
The top graft was done on the 12th January, the bottom graft on the 14th January.
A difference of two days. Notice the top graft cotyledons have opened out, there is also a hint the shoot is forming.
Looks like the test will be successful.

Update 7/2/18:
The first graft done is doing well the other is RIP(Rot In Peace), think it was just a little too small.
Will try again when there's a bit of spare time.
Cheers
Update 21/3/18:
The scion is now large enough to harden off prior to grafting it to it's final rootstock.
Cheers
