I was out on my overcrowded patio earlier this afternoon, having a look at my trees. This immediately caught my eye, and I thought I had better get some help from the knowledgeable folks here. This is a pretty recent development, probably in the last day or two. I didn’t notice this the day before yesterday, and yesterday I wasn’t out on the patio until nighttime. I was watering everything, but could have missed it as the lighting isn’t great. So far, it’s only the one branch. The rest of the foliage looks good, as can be seen in the picture. Does anyone know what may be causing this? Google wasn’t much help so far.
