Review: Bloom Booster - Have used Miracle-Gro general fertilizer for many years, so thought I'd give the booster a try. My plants reaction is amazing! Easily twice as many blooms per plant. And they produced them very quickly. As instructed I waited to apply it until the plants were beginning to bud, followed by an explosion of flowers. Plants are also very healthy and happy. Highly recommend for flowering plants. In my zone 10, some flowers that had struggled, are now flourishing covered with flowers Review: Five Stars - Great product for the bloom stage of cannabis ## Features - Promotes more blooms for greater color! *vs. unfed plants - Feed every 2 weeks - Instantly feeds for beautiful results - Use with the Miracle-Gro Garden Feeder or a watering can ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00C4TPN7K | | Brand | Miracle-Gro | | Brand Name | Miracle-Gro | | Coverage | Flowers and flowering plants | | Customer Reviews | 4.8 out of 5 stars 4,154 Reviews | | Global Trade Identification Number | 07129984811532 | | Item Form | Liquid | | Item Type Name | Flower Food | | Item Weight | 4 Pounds | | Item form | Liquid | | Item weight | 4 Pounds | | Liquid Volume | 4 Liters | | Liquid volume | 4 Liters | | Manufacturer | Arett Sales - LG | | Mixing Ratio | 10:52:10 | | Model Number | Miracle Gro - 146002 | | Number of Items | 1 | | Part Number | Miracle Gro - 146002 | | Specific Uses For Product | Plant Growth | | Specific uses for product | Plant Growth | | Target Species | flowers | | UPC | 073561460019 720698810568 720698840619 | | Unit Count | 64 Grams | ## Product Details - **Brand:** Miracle-Gro - **Item form:** Liquid - **Item weight:** 227 g - **Liquid volume:** 4 Liters - **Specific uses for product:** Plant Growth ## Images ![Water Soluble Bloom Booster Flower Food 4 lb - Image 1](https://m.media-amazon.com/images/I/715ONFm9KtL.jpg) ## Questions & Answers **Q: What is the n-p-k for this product? i'm surprised it's not mentioned in the product description. thank you.** A: Definitely NOT 10-52-10. 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Bloom Booster *by D***H on 29 April 2026* Have used Miracle-Gro general fertilizer for many years, so thought I'd give the booster a try.
