what is wrong with my grape vine
Hello! I planted 8 grape vines last spring (2012). I left them alone the first year. This year I have started pruning them and 6 of the 8 look great! However, I have 2 that look like this. They are growing very slowly and the leaves are almost all yellow. Only a few of the older leaves are dark green. I'm not sure what is wrong.
I haven't fertilized. They are on a drip system and I have checked the soil and they are getting plenty of water. The other vines which are on the same drip system look just fine. Any ideas what could be going on?
