Flavor Grenade Damage

Just inspected my FG and found that a number of scaffolds are dead.
While the rest of them are still green, they are not leafing out as they
should by this time of year. There is also a 6 inch long vertical split in the bark
near the base of the tree. There is no insect damage nor disease, so I’m wondering, if the recent freeze has killed this tree. The tree is about 5 years old and produced an abundant crop last year.
Has anyone else have this happen to a pluot? It’s on myro.

I think that would be freeze damage. I did not have that happen to my plums but that did happen to my figs and pomegranates and has happened to my citrus in the past.

How low did it get in your area?

It got down to 23, but the problem started before the freeze. When it
bloomed, only half of the tree bloomed, while the other half stayed
dormant. I figured the other half would break dormancy, when the
weather became more consistently warm. But when that didn’t happen,
I cut into some of the branches and they were totally brown and dead.
So now I have a half dead tree and can’t figure out why. I’ve never seen
this before on any tree, and am totally puzzled. I was able to order another
FG from Raintree yesterday as a backup.
When your poms froze, did they come back? I made the mistake of planting
mine in early march, when I thought spring had arrived and they all froze,
but the wood is still green. So I’ hoping they’ll come back, or is that wishful
thinking.

I have heard of this happening when roots are damaged.(half the tree leafing out). Could you have a girdled root?

That doesn’t seem like freeze damage.Something was going on either with the roots or maybe graft.I have a young Flavor Grenade that has done fine through a couple of 15F winters. Brady

Can’t be girdled. It’s always been in the ground. It was planted dormant
bare root with no soil amendments. So there was nothing to girdle the roots.
This tree is over 5 years old and has never had this problem and produced
an abundant crop last year.

OK, well that’s not it then. Something caused it, Good luck with it. it would be nice to find out what it is so the replacement doesn’t suffer the same fate.

I think I’ve figured out what the problem is. The tree somehow contracted
fire blight from an infected pear that I had to remove last year. I didn’t
know that plums could get FB, but after researching the issue, that’s
what it has to be. It’s in the trunk and you can see the all too familiar oozing.
Although the tree is not totally dead, once it’s in the trunk, it’s toast and I
won’t allow it to spread to my other trees. So I’ll be removing it this week.
It’s a bummer, because it produces outstanding fruit, and now I have to
start over with a new tree.

Canker is similar to FB right? Isn’t that a more likely cause? I don’t think stone fruits get the FB organism.

I haven’t had FB on anything in the last 40 yrs but have lost trees to canker.

My Red Silk is coming back from the ground and Mae looks like it will too. Desertnyi really got hit hard not sure about it yet.

I have to agree, this seems like canker. FB to my knowledge does not infect stone fruits.

The bark split might be from sudden temperature change and the rest reminds me of something we discussed in this thread.

It isn’t canker. There are no canker areas on the entire tree. It’s definitely FB,
The wood under the bark even has the characteristic red streaks. I didn’t think
plums could get FB either, but I’m a believer now. Google FB in plums.

This report does appear to indicate that FB can infect plums. I do think it’s not common.
