Could this split be causing my cones and leaves to brown? I assumed that it was due to a lack of water. It has been really dry here lately. It could be that the bine has grown too large, I only trained two rather than three bines from this crown. I've also heard that sisal twine can contract and cause problems like this. There are splits like the ones pictured all up and down this bine. It is a third year crown take a look at the pictures and let me know what you guys think. Thanks.
