i have this little pyracantha which is doing fine in general but i find the form of the leaves a little bit disturbing. As you can see on the pictures all the foliage is more or less in a halfpipe shape along the vein and not really a flat leaf.
The tree was repotted this spring. It hat a very compacted soil but now it is well draining and watering seems fine as well.
From time to time some leaves turn yellow and fall off but besides that the tree is in good health. But i remember when i bought the tree two years ago the leaves were definitely more flat and not so narrow halfpipe shaped.
Does anybody have an idea if this is a lack of some special mineral or something else?
Thank you for your ideas.
