Two days ago we added a small amount of bonemeal to side dress the garlic. Colorado soil isn't the most nutrient rich soil and it takes a little help. We use bonemeal because it breaks down slower and we have found that the slower the nutrients absorb the more vigorous the plant. Watered the garlic afterwards but not much because the mulch is keeping the plants well moist. One thing about here is that we get a lot of sun.
