Can I use Sulphate of Potash and Blood and Bone on my native plants?
I understand that Sulphate of Potash can be mixed with Blood and Bone to make a complete organic fertilizer. Is this OK for natives and what ratio to mix please?
yes blood and bone doesn't naturally contain potassium so you can add sulfate of potash 1 part in 10, or you can look for Yates Professional Blood and Bone (Plus Potash) with added potash. It is ok to use on natives.
