Q.Blueberry Bush Fertilizer
I’ve been told by the local nursery I can use coffee grounds to add nutrients and acid to the soil around my blueberry bushes to promote berry growth. I have a bag of unused (not brewed) coffee grounds. Should I dilute the grounds in water and strain the grounds out first or can I put the fresh grounds directly on the soil around my bushes? I wasn’t sure if the fresh grounds would be too strong for the bushes and I didn’t want to shock them and potentially harm them. Thank you

Fresh coffee grounds are better if you want the acidic benefit. Most people use a fertilizer recommended for azaleas and rhododendrons.
