Organic rice hulls is also recommended to make your grapes healthy and beautiful foliage.
I use rice hulls for my Dominga grape vines, and it looks lovely and healthy. it is organic and safe from pests.
The properties are anti-bacterial and rich in nitrogen. This is first fertilizer I use in our garden. I have seen foliage but not a bunch of fruiting. If you want bunches, just use Urea Fertilizers.
