what's happening to my annona grafts?

[boxturtle]

this is the second time it happened.  it was going strong then leaves starts looking like this.  The other one was much bigger then this one and did the same thing.   just a failed graft? overwatered?

[bsbullie]

Were both "failed" graftd in the summer?  How long from the time of grafting to that flush at that stage?

[sapote]

This looks like the root stock is dying and not the graft.

[boxturtle]

the 1st one was about two months and yes it was mid summer this one about a month......root stock is very much alive because new growth buds still sprouting.....they look like not getting water but soil is moist.  Thought it was the heat but usually when I have that happens leaves would brown in a day or two.   the first one took over a week to die....this one has been 3 days now.....both were in partial shade

[bsbullie]

I know this is not a great time of year to graft annonas.  I wonder if that is playing a roll here...

Yah, that's what I was thinking.

I agree it looks like a rootstock problem.

I think you can save it. I had a pierce that was like that last year. Gary from laguna hills told me to bareroot it and put it in their soil and baby it for a few months. Roots looked dead to me when I washed away the native soil. I put it in a cheap plastic greenhouse with misters over winter and it sprouted growth from both rootstock and main graft. It’s in ground now and isn’t as robust as my others but it’s growing and I’ll give it another season before judging.

my recommendation toanyone on Anona is to put your seedlings into ground first so they have good root system. remember these grow quickly. after at least 1-yr in ground with multiple branches, you start grafting. I have little success but mostly failures in grafting when in pots, as pots here in So Cal are susceptible to diseases and water problems given unstable weather. over-watering or under-watering is a major issue.

Hows the bottom of the pot look?  Drain holes covered in white crust?

[boxturtle]

so I went and barerooted it....didnt know how to do it so lost most of it Brad, drain holes weren't clogged and no white stuff.  I use promix hp and mix about a 3rd of bark into it.  I felt the soil ...it was moist but not water logged.  the base of the stump does seem to have excessive moisture tho. 
     Behl I did about 8 grafts the 1st time and only one lost so far ....this one was 1 out of 10.  the 1st time I just thought it was stress due to that 112 day....i did place all of them in full shade for the day but only one reacted this way.  I consider myself lucky.  But it happen again to this one in the 2nd batch so i was puzzled.   
    The first one was a pierce this one is a Selma.  in both batch had couple of the same that survived and are thriving in pot.  That's why it's puzzling.

The roots starved to death during the month or two after all the leaves were cut off the root-stock during high-metabolism/ active growth time of year.

Four to six good-sized leaves must be left on the root-stock until there are at least that many mature, hardened up leaves on the scion.  Tender new growth is not photosynthesizing enough for its own needs, much less for the needs of the roots and trunk, which are all live cells needing glucose to survive.  Remember that fertilizers are mineral supplements, not food, in the sense of source of energy to live.  Fertilizers will actually make a situation like this much worse.  And any disease or pest finds the plant defenseless.

Remember to know the difference between buds and leaves.  The root-stocks' buds must be destroyed, carefully, without removing the leaves.

aha! Makes sense. Thanks for the 'splanation. I've had this happen to me a couple of times.

that was my other thought maybe I topped the rootstock too soon.  I guess I luck out with my other grafts that I did the same.  I thought the new growth was enough and the rootstock would put all it's energy into the graft to survive

[boxturtle]

thanks all so much......so much more to learn lol that's why I love this site members have a wealth of knowledge and the heart to share

Thank you for that explanation. Very helpful

my recommendation toanyone on Anona is to put your seedlings into ground first so they have good root system.

That's what I did, potted up a cherimoya seedling before grafting your budwood - Sabor, Campas, Pierce and Behl.  The seedling was only established about 3 weeks though, but as you've seen quickly became a 5' tree of 6 successful grafts.

Mark, you have a serious green thumb  
I recall seeing some posts when you made those grafts back in March I believe.
Nice.  Keep a photorecord of this and share from time to time.
