Blood Meal: Complete Guide
One of the strongest organic nitrogen sources at 12-0-0, blood meal releases nitrogen within 1-2 weeks rather than the months most organics require. Apply 5-8 lbs per 1,000 sq ft for corn, brassicas, and leafy greens. Can burn seedlings if overapplied despite its organic label. Also acidifies soil slightly, benefiting blueberries but harming alkaline-loving plants.
