I put crushed eggshells out there, but not in that quantity. Plus some Super Phosphate to encourage blooms (although sufficient blooms don’t seem to be much of a problem anyway.) But I’ll give a shot at fruit formation time a try - maybe the Super Phosphate all gets taken up by the time the fruits are starting to form.
My Rural King store has bone meal, 3 lbs. for $7. But that won’t go far if you are recommending a cup for each plant?
You can go less with the bone meal. I’m just generous! I looked at my ‘scoop’ and it’s 3/4 cup at best.
