Our custom slow-release fertilizer blend is great for first year hop plants. This is the exact formula we use on our large commercial hop fields. We’ve found this mixture to be strong enough to enhance growth, but not so harsh that it burns up the young shoots. Our custom blend is a mix of N, K, P, and dried kelp. Each bag will provide sufficient fertilizer to cover five plants during their first season of growth. Instructions for use are included on the bag.
