I used blood meal this past week. I put in in the bottom of my seed flats on top of a few leaves I put at the bottom of the planting mixture. I bought it at Agway. Is not cheap $12 a one pound bag! I like it. Urea is also good for nitrogen and is much cheaper!
I enjoy fishing ,gardening and a solar greenhouse! carpet installation repair and sales for over 45 years! I am the inventor of the Bobber With A Brain - Fishing Bobber!
