Just for info, those reading this may also like to read this that I wrote ages ago & keep on file:
"NPK - N= nitrogen P=phosphorous and K=potash, the three main food elements necessary for plant life. Basically, nitrogen is required for foliage growth, phosphorous for root growth and potash for growth of flowers and fruit.
Blood meal is a slaughter house by-product and is an excellent source of quickly available organic nitrogen, when used as a top dressing and watered in.
Blood meal is completely soluble and can be mixed with water and used as a liquid fertilizer.
Fish meal is a great natural fertilizer, high in phosphorous and high in organic nitrogen. Fish meal is quick acting, offering a sustained supply of nutrients.
Bone meal is used as a long-lasting source of phosphorous as well as low levels of nitrogen, potassium and calcium. The extremely slow availability of nutrients from bone meal makes it a very safe fertilizer, especially when planting of potting very young or new plants."
