Afternoon all.We are trying to rejig some of the garden beds since moving into a new home.The soil is a good rich clay and i have been watering and turning over when damp.I got hold of bales of pea straw which i put through the shredder/mulcher.Turned that into the soil and added small quantities of gypsum.To that i am thinking of adding blood and bone.Am i wasting my money adding the blood and bone now,as we dont want to replant until the weather cools considerably.Probably what i am asking does blood and bone have a useby date and if so for how long does fertilizer remain active,Regards………….AL
