Answer: Yellowing leaves can indicate too much water so be careful not to overwater your grapevines. One deep soaking per week should be all that is required. Grapes can take several years to mature before they will develop grapes so you just need to be patient with yours. In a few yeares they will have more grapes than you can imagine. Don't feed your grapevines or spray them with anything. Just water deeply once each week, give them lots of sunshine, and they will grow well for you. Enjoy!
