anyone know muscadines?
I bought two muscadines at a big box store last year and planted them to grow up and along a fence (each in a "T" formation). One of them just exploded in growth; the second barely inches along, and has more or less stopped growing. Same location, planted at the same time, same routine.
So that's just weird, but if anyone might have an explanation I'm interested to know.
But to my actual question: this is year two with the vines. I trimmed them in February back to three buds on the shoots and in May I had a few grape buds (more, strangely, on the slower growing one). But those buds have disappeared and the ends of the tendrils look burnt. The vines otherwise look ok: the one is still growing like crazy, they have a few red spots on the leaves and maybe some yellowing.
Does all of this point in the direction of one problem? I'm thinking that it needs magnesium, but I really have no idea. Any thoughts?
