My Issai Kiwi looks like it may have chlorosis. Also some distortion/mottling as well. The new green growth on them looked great, and I come back to this. Anyone successfully growing hardy Kiwi? This is its second year, and I’ve had problems both years now. Maybe it’s getting too much sun?
Ross, I have exactly the same leaves on my apple trees as on your second picture. I was wondering why is that? Three of my four apple trees do not look happy. The few apples look too small and undeveloped. The leaves are curled inward and there is light discoloration as on your picture. I did not see any insects except for June beetles. I am thinking it was the dry and the hot weather that stressed my apples. They are on Emla 26 rootstock which is not resistant to drought. The better looking apple is located in the shadier and slightly wetter spot of the garden.
I was going to say they look a little fertilizer burned to me, but I have more experience with that problem with plants rather than trees. I associate thicker leaves that “scallop” themselves into vaguely tortellini shapes with micronutrient lock ups causing burn, as opposed to rams horns indicating nitrogen excess. edit If you recently moved them into a sunnier slot, my gut would say fertilizer burn from sun shock, ie they were well fertilzed for shade but couldn’t take up the micros to out heal the transition into more sun. A foliar spray and a shade sail may help.
Not sure what it is but when we get to the bottom of it we will all be a lot happier! I posted a problem I am having on apples a week or two ago. Mine is two fold, but I have some leaves that look exactly like your apple. Dropping off a leaf sample at our local diagnostic lab today. Where are you located Ross? Antmary are you located in Nebraska?
Right now I am leaning towards a couple of things, excessive early season moisture, then abnormal early summer extreme heat. Though I think my trees are also lacking in Zinc as well. The leaf symptoms we are all experiencing is very similar to Zinc and Magnesium deficiency. Likely compounded by the wacky environmental growing conditions this year. I applied some 10-10-10 fertilizer early in the spring around some of my trees, but the condition is also occuring on apples that are on “virgin” soil that was not fertilized this year at all. Also I have seen almost zero bugs on my trees this year.
Take it for what its worth, just a follow up from my end. My apples are showing identical symptoms. Just got the leaf tissue analysis back from the lab, confirming what I thought my research had led me to. Deficient in Zinc and Copper. Low in Magnesium, Calcium and Boron. Sufficient in the major nutrients. We will let the crop consultant give me the recommendations from here.
The apples at least don’t look like anything to be alarmed about at this point imo Sometimes the best course of action is to take no action at all. If you go doing a bunch of stuff you’ll have a hard time knowing what the heck is going on later should the condition worsen or improve.
If you let the apples alone there is a very strong chance they will be fine. I doubt it’s nutrient related, though it is possible.
AMV or something similiar is a more likely possibility imo, but I’d let them alone…for now at least.
Why in the world would you make such a comment when someone just made a post to the contrary with knowledge and facts to indicate that it could very be the cause of it. I did not tell Ross to go dump a bunch of fertilizer on the tree, but I would suggest that he look into having a soil and leaf analysis run if he is still concerned about his trees appearance and then make an EDUCATED DECISION from there.
