When to Add Blood Meal to the Garden

Blood meal is best added when a soil test or plant symptoms indicate nitrogen deficiency, such as yellowing older leaves, weak stems, and slow growth. Many growers apply it in early spring to support vegetative growth and again mid-season for heavy feeders if foliage starts to pale, especially in intensively used beds. ^{Read more}

How to Use Blood Meal as Fertilizer

Blood meal is typically applied as a dry powder and worked into the top few centimeters of soil or used as a side-dress around established plants, then watered in thoroughly. For home gardens, common rates are about 2–3 pounds (roughly 1–1.5 kg) per 100 square feet, or 1–2 teaspoons per planting hole or per plant for side-dressing, always following product-specific instructions to avoid over-application.

What Plants Is Blood Meal Good For?

Blood meal is especially beneficial for nitrogen-hungry, leafy and vegetative crops such as brassicas (cabbage, broccoli, kale), corn, squash, onions, and leafy greens like spinach and lettuce. It also supports vigorous foliage on ornamentals and lawns where rapid green-up is desired, provided soil pH and other nutrients are in balance. ^{Read more}

Can You Sprinkle Blood Meal on Top of Soil?

Blood meal can be sprinkled on the soil surface as a top-dress and then lightly scratched in or watered in so it contacts moist soil and begins to break down. Leaving it fully exposed on the surface is less efficient and may attract animals, so a light incorporation into the top 2–5 cm of soil is usually recommended.^[3][2]

Which Plants Don’t Like Blood and Bone?

Plants that prefer low-nutrient or lean, free-draining soils—such as many succulents, cacti, some Mediterranean herbs, and some heathers and lobelias—often do poorly with rich blood-and-bone type fertilizers because excess nitrogen and phosphorus can cause weak, lush growth or root stress. Nitrogen-fixing legumes such as peas and beans also usually do not need blood meal, as additional nitrogen adds little benefit and may even reduce nodulation.^{[8][9][10][3]}

How to Apply Blood Meal to Correct Depleted Nitrogen

To correct clearly depleted nitrogen, start by confirming deficiency with a soil test or consistent symptoms (pale, yellowing older leaves and slow growth across the bed). Then apply blood meal at label rates (commonly 2–3 lbs per 100 sq ft or a light side-dress band around plants), water it in well, and re-check growth over the next 1–3 weeks, avoiding repeated heavy doses that could over-acidify soil or burn roots. ^{Read more}

Blood Meal vs. Bone Meal Fertilizer: What’s the Difference?

Blood meal is a fast-acting organic fertilizer rich in nitrogen that promotes leafy growth, while bone meal is high in phosphorus and calcium, supporting strong roots, flowering, and fruit development. Visit here.
