New grafts growth, leaves browning.

[buckvelvet]

Sorry didn't snap a pic before work but the yellow leaves (grew in basement for 3 weeks) have browned since bringing them outside the past week.

Any thoughts on why this is happening instead of them turning green? Plenty of sunshine....

 

[buckvelvet]

Will they rebound or did I just totally shoot myself in the foot?

Doesn't sound good

Thanks capt positive. :)

They are still yellow but the outside of the leaves like the rim(?) are turning brown.

Most likely environmental stress. Too much sun too fast. Or if they are in a spot where they are subject to strong winds. New leaves are pretty tender, doesnt take much to cause a little damage and it shows on the margin first in my experience. Many times it will just end up being the edges that will turn brown and the interior of the leaf will be fine.

I know what a failed graft feels like. There is always next year, let it bud out, so the stock lives.

Well hell Dipper I could have told ya my grafts failed 15 of these 16 did all the roostock are living. I'm mostly talking about rootstock growth not grafted scions growing.

BV,

I'd remove as much stress as possible meaning protect them from wind and direct sunlight. Make sure they are moist but, not swamped with water. Then wait and see. I lost a graft last year that was just leafing out and it got toasted by a 90 degree day that wasn't supposed to have happened. There's a lot of factors going on with the whole grafting process. The less stress the better.

The yellow leaves are stressed from lack of sun so they need to be pampered until they turn the correct color and get well. Were they turning green before the brown phase started?

I'm not home during the day, its either put them in sunlight or keep them in darkness forever. Its all or none and hope they survive.

BV,

Setup something that blocks the sun. A piece of plywood , a cardboard box, a trash can, a tarp , place on the north side of a building, or a behind a bush, etc.

So the yellow/brown leaves are on the rootstock or the grafts?

1 graft, 15 rootstock. Not in the same containers so not some sort of contamination. I plan on getting in the ground soon so I don't kill them. Just a bit disheartening...

They have been in the sun now since ohh last Friday so almost a week, I bring them in at night until it warms out above 40.

I brought mine from dark cool Into my house with 62 to 67 degrees near a window and they are really green. Then I put them in root trappers and they have been back in garage since its been cold at night. I will put them out in shaded to partly sunny for a few days then just let them soak up the sun after that. Hope to plant many end of May or sooner

I can't help here I never had yellow leaves

 

[buckvelvet]

Here is a pic of what is happening but they seem to be recovery now. This is a B118 rootstock pic.

Here is the honeycrisp that woke up.

You answered your own question...too much sunshine and too much wind most likely. Hardening off is a weeks long process

You are correct, another village idiot ramble...

 

[buckvelvet]

BV,

Just to clarify. Were your leaves yellow from being inside in the dark? Or did they turn yellow once they were outside?

They were deff yellow before going outside as they had never had sunlight like Eds way of doing things. I just didn't do the right steps for hardening off or slowly exposing them to light, damn on my end.

It has been cool enough in my area that i've had my trees out in my garage, in a north facing window.

You can defuse the light by putting a white kitchen garbage bag over your 5 gallon pale. I would also start by having them in the shade like at the north side of the garage.

I moved my bucket full of trees outside today and covered them up with a white sheet. Beautiful day out there, high of 65 today.

 

[aerospacefarmer]

I put all my root trappers outside this afternoon with 58 degrees and partly sunny. Going down to 43 tonight and 70 tomorrow. Most will get some sun during day but not all day. They will be out until planted from now on assuming no freezing nights which doesn't look like that will be happening.

Just wanted to let you guys know that they recovered and have turned green, here is the honeycrisp.
