Buyer’s Guide: What to Consider
Choosing the right blood meal involves considering your garden’s specific needs, the size of your planting area, and your gardening philosophy. This guide highlights key factors to help you make an informed decision and get the most out of this powerful organic fertilizer.
- Nitrogen Content: Blood meal is prized for its high nitrogen content, typically around 12-0-0. This makes it ideal for promoting leafy growth and greening up plants. Check the NPK ratio on the package to ensure it meets your plants' needs; a 12-0-0 is standard and effective.
- Organic Certification: If you're committed to organic gardening, look for products that are OMRI Listed or certified organic. This ensures the blood meal is free from synthetic additives and meets strict standards for organic production. Many top brands, like Espoma and Down To Earth, offer certified options.
- Application Method: Blood meal can be applied by sprinkling it on the soil surface and watering in, or by mixing it into the soil before planting. Some products are designed for specific methods, so consider how you prefer to feed your plants. Always follow the instructions on the label for best results.
- Packaging Size: Blood meal comes in various sizes, from small 0.5-pound bags to bulk 25-pound options. Choose a size that matches your garden's needs. Small bags are great for containers or trial, while larger bags offer better value for extensive gardens.
- Pest Deterrent Properties: The strong scent of blood meal can deter animals like deer, rabbits, and squirrels from munching on your plants. If pest control is a concern, look for products that highlight this benefit. However, be aware that the smell may also attract some animals, so use with caution.
