Blood, Fish & Bone Fertiliser

Dear Harrod

I have a box of old Blood Fish and Bone – 5 years old and it has “melted”.  Can I mix it with water and use it for general floral garden use?

Thanks in anticipation.  Paul Overton

Dear Paul


You could certainly give it a try, but only on flowers, not on vegetables. 


Blood fish and bone is usually used in soil preparation and will take a little while to break down in the soil so I’m not sure how well it will mix with water.


Personally I would dispose of your melted box and start again with a fresh new one.


Kindest Regards
