Another diagnostic question today. Below you can see the lower portion of a tree trunk whose left half is obviously wet:
What is directly causing the wetness (in other words, what environmental factor), and can you guess what led to this problem indirectly?
I’ll eliminate some of the obvious possibilities: it’s not from dog pee, nor is it from a directional sprinkler. And the answer to the second question is not in this close up photo, but will be revealed on Monday.
Why do I torment you like this? Well, if nothing else, it gives you an idea of what distance diagnosis can be like – which is what we tend to do more and more, thanks to the internet and digital cameras. Someone will send a photo of a plant problem and expect us to figure it out, but the answer may lie outside the field of view.
In any case, have fun!
