My new grapevines are not growing well. What kind of fertilizer is best for them?

I just planted some 2 year Concords and they look like sticks:eek:
It's been a couple weeks, but we haven't had much sun. How long have yours been in the ground?

Not much activity on my grape vine yet this year. But, it's like 30-40+ years old. When it takes off, it takes off. Shoots are like 30' or longer.
