This product is the 5.5lb box. It's npk is 15-30-15. This is not mentioned in the description which it should be. I bought this thinking it was 10-52-10. I'm totally bummed because this is the 2nd time I've placed this order only to find that the npk is either not mentioned or is different. NOT COOL!!! **Q: Why is this superior to regular Miracle-Gro for flowering window baskets?** A: Fertilizers have three numbers: NPK: Nitrogen(N)-Phosphorous(P)-Potassium(K): Nitrogen assists the plant grow more leaves, Phosphorous is good for flower production, and Potassium is good for overall health of the plant. The regular all purpose Miracle Grow's numbers are:24-8-16 whereas the Bloom Booster's ratings are: 10-52-10. Bloom Booster has relatively more Phosphorous; thus it is expected to help the plant to grow more buds and fruits. I use it about 1/3 rd spoon ( a weak solution) per gallon for my container plants almost alternate days with great results. **Q: is this product good for vegetable blossoms and setting fruit** A: Absolutely! The Bloom Booster is heavy on the nutrient that 1, develops roots and root systems and 2, helps in the development of the blossoms/flowers that develop into fruits and vegetables. **Q: Can it be used for indoor pot plant?** A: What kind of pot?Works great for me.Youcan also spray on leafs,but not when flowering. ## Frequently Bought Together - Miracle-Gro Water Soluble Bloom Booster Flower Food - Miracle-Gro Water Soluble All Purpose Plant Food, Fertilizer for Indoor or Outdoor Flowers, Vegetables or Trees, 3 lbs. - Miracle-Gro Garden Feeder with Water Soluble All Purpose Plant Food, Hose-end Feeder for Outdoor Plants, 1 lb. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/364385298-miracle-gro-water-soluble-bloom-booster-flower-food-4-lb](https://www.desertcart.us/products/364385298-miracle-gro-water-soluble-bloom-booster-flower-food-4-lb) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-24*
