Hi all! I have a lovely North Wind Palmatum/Pseudosieboldianum hybrid. It is in Minneapolis (5A) with eastern exposure and afternoon shade. This is its third year in the ground. It has been a mostly pleasant summer but with some odd ups and downs. A couple scorcher spells, hints of droughts, and then some long rainy spells. Lately, it has been hot and raining a lot. I’m seeing leaf droop and I’m worried the tree may be getting overwatered. I’d appreciate any advice! For context: The emerging growth does tend to be that hot orange, so I’m not worried about that. Our soil does not drain particularly well, but I have three red dissectum, and Aureum, Osakazuki, and Samidare, all of which are doing fine. So I don’t think the culture is particularly problematic for JMs. Finally, the interior portion of the tree (shown) does not seem to have this problem. I don’t fertilize but did add 1-1.5” of compost this spring.
I think this cultivar is a bit tetchy when it comes to stress. But to my eye, it just looks a little stressed, not in danger, and not overwatered. -E
I agree with emery. I don't see major overwatering damage. I've been battling the this issue with a couple of my trees. Yours doesn't look too bad. But to guard against excessive water I typically I add pine fines and compost to the native soil and position the top of the root ball 2-3" higher than the ground level when planting. Also the structure beside your tree doesn't have gutters so the water running off the roof could put too much water on to your tree. If it were mine I would wait until fall and dig the tree up and move it back from the structure and replant a little higher.
Both of theses plants are on pots on drip irrigation. First is a A.P Koto no Ito. When this happened I got 5-6" of rain in one week. I had the irrigation off but this happened anyway. I pruned out the damage and no further damage was incurred. Second tree is a seedling that I was caring for while a friend that was on a 3 week vacation. I noticed this damage within the first week. None of my other trees showed any problems. I notice my friend used potting soil in his pot. I took off the irrigation and pruned the damage. Lesson learned about potting soil. Holds too much moisture
