Hi Tattianna, Garlic, like onions, are really hungry plants, so I always mix a couple of handfuls of fish, blood & bone into bucket of compost and trowel-in a handful of that mix into each planting position. Even so, my garlic wasn't as good as usual this year either; I'm putting it down the the weather - all of that rain probably washed a lot of the nutrients away and garlic does need some good hot sunny days towards its harvesting time..
