You've planted your Garlic last fall, the shoots germinated before Christmas, they began to grow larger the past two months. Now What. You will be getting ready to see the scape flowers in June and Harvesting will come sometime in July.
Now ( Early May) is the perfect time to give your plants a good strong feeding.
I use granular fish meal ( which is high in Nitrogen) to scratch in around the base of each plant. I will water generously to ensure that the soil absorbs the product and then cover the bed in straw to inhibit weed growth.
This extra shot of nutrition will assist in developing a larger garlic bulb for when you harvest. You may do one more feeding, before the flowering scape appears.
No feeding after that until your garlic is harvested!
