Issue with grafted seedling

[ohcactusisgood]

I grafted a bunch of Lophs a while ago. Some on peres and one on a pachanoi. I had a really good success rate. And all the ones on peres are growing well. Unfortunately the one on pachanoi is not doing so well. I think it's because on day three I came in and saw a bunch of Thrips on the seeding. I got rid of them all, and then I gave the plants a bunch of systemics. I even put the pachanoi pup outside in the backyard. So far though it doesn't seem to have grown at all! everything looks healthy, and the seedling it definitely grafted and is rigid with water. Any ideas?

PS the first one doesn't look as good as the second because it didn't graft onto the center of the pere as well. So it's slowly getting connected to the stock and hopefully will speed up.

Looks sorta like you didn't connect the vascular tissue of the two plants. The Lophophora looks like its fully inside the T. pachanoi's vascular ring when it needs to be offset and on top of it.

I agree with Michael, it looks like it's missed the vascular bundle. It happens sometimes when everything shrinks and settles in, sometimes they just slip sideways if they aren't secured properly.

I'd be tempted to cut that one off and graft it to a peres before it shrivels up and dies.

Although a scion that size can be successfully grafted to a trich, I normally choose one a bit bigger for a graft to a trich. They are bit easier to handle and there's a better chance of getting an overlap on the vascular bundles.

Not so sure. It is pretty solid on the grafting stock so it's getting water enough. Even the red one that was not quite on there is doing really well.

Here are some more photos but I did just dust it with sulphur.

Looks like there is an offset coming from the grafting stock though. I hope maybe the sulphur dusting will make it wake up a bit and I will cut the offset off.

I can't say for sure, but from that angle it doesn't look like there's much overlap of the vascular bundles if any. If we could see it from another angle (about 120 deg from the angle of pic 2 above) we'd know for sure.

I've seen them hang on like that for months and normally they slowly shrivel and die. Even though the graft has taken it doesn't always guarantee it will survive.

IMHE, if there's a slight over lap, it'll take the whole graft some time to grow. Until the connection develops and has more mass to feed the graft.

Looks like it lived. Hopefully it will keep up with its brothers.
