@utahxericman,
Thanks so much for your help! Meijer's had one of those
https://www.amazon.com/dp/B000P0DK1Q/ Miracle-Gro Garden Feeders (with the 1-Pound Miracle-Gro All Purpose Plant Food attached). I can go back and get it and dump out the All Purpose Plant Food granules, rinse, dry and use my last remaining Bloom Booster granules with the Garden Feeder. I might have my hubby drive around to WalMart and/or Lowe's and see if they have any of the Bloom Booster boxes still available.
Never did use the MG fertilizers before, so I really appreciate all you help!
