FREQUENTLY ASKED QUESTIONS
What is blood meal fertilizer?

Will blood meal attract animals?
Blood meal can attract dogs, cats, and wildlife due to its scent. Mix it into soil rather than leaving on surface, and consider using barriers or repellents if animals are a concern. Store in a secure, sealed container.

Blood meal provides nitrogen for 6-8 weeks, making it a medium-release organic fertilizer. Reapply every 4-6 weeks during active growing season for best results.

Bloodmeal for Sweetcorn

Used the bloodmeal on sweetcorn. I have bought this product before and it is the only bovine source that I could find out there. The abundance of nitrogen does seem to help the corn take off
