Review: Switched From All Organic, Will Never Go Back - I've been using the JR brand fertilizers now for three years. I used to be one of those "staunch organic" gardeners that thought poorly of chemically derived fertilizers. I started gardening in the subarctic and found that I just wasn't getting enough performance in my short garden season from organic ferts. I wanted to make a change. I did a lot of research and found this company. I liked that they used soil science and were a soil lab first and foremost. They have clearly been at this game for a good long time (under a couple names) and had a good reputation. They have a clear understanding of the nuances of various plants out there and the needs of a gardener that are trying to care for those plants. I first tried the all purpose and within one week, I was sold on the product line. This stuff is amazing and forever changed my entire opinion of non-organic fertilizers. The bottom line, if my plants were unhappy with it, they wouldn't respond as well as they do. Within two days of applying this, you will see significant and noticeable growth. The liquid application works quickly and effectively. When used in appropriate dosages, and even a little bit more, there is no risk of fertilizer burn. I use the JR Peters hose end sprayer to apply it to my large garden. While I'm not the biggest fan of the sprayer, it gets a large job done quickly. I apply every 7-10 days, per the recommendation, all season long. My largest garden is a community garden and we are constantly getting compliments and are asked about our "secret" - it's JR Peter's fertilizers. Our garden is consistently in the top producing gardens at our community garden. I also love that this fertilizer features a constant feed rate. (1 teaspoon per gallon.) I use sub-irrigated containers in some of my gardening applications and treat them similar to hydroponics. This fertilizer is extremely good when used with this technique, I get incredibly rapid growth rates and maturity times. Even when used in this constant feed application, I have no complaints about any produce treated in this manner. For all of my nightshades, I use the Tomato Feed platform for the first two applications of fertilizer. (This ensures appropriate calcium and magnesium throughout the season.) I then switch to a 50/50 mix of the all-purpose and bloom booster and continue this rate for the rest of the season. I have found the mix to be a more effective balance between flowering and growth than bloom booster alone. For most other veggies, I use just the all purpose. For my flower pots and beds, I use straight bloom booster throughout the entire season. I have completely converted over to the JR Peter's brand fertilizers and use it exclusively across everything, even my indoor citrus and houseplants using those purpose-focused products as well. Since switching, our production rates have shot through the roof and we even do well in "bad seasons" across most of our garden. While fellow gardeners complain, we reap incredible benefits because of this product line. I buy the bloom booster and all purpose by the 25lb bag these days and one bag will last me almost 3 seasons. I can't recommend this stuff enough, honestly! Review: IT WORKS GREAT πŸ‘ - I've been using this fertilizer for quite a long time and even with the change of names of the Fertilizer. I absolutely love & recommend this for use when your plants start to flower/bloom. Along with the using Peter's grow fertilizer I've never had any problems or issues with the plants. They seem to love both of the amazing fertilizers that I've been using for 20+ years. The price isn't very expensive, I buy a large bag of it, and it will last me for 2 years. Which is inexpensive if you have the money to buy a 20lb bag of it. Which I also suggest to save you money πŸ’°. ## Features - You will receive 2 bags of fertilizer per order - 10-30-20 Analysis - Great for producing brighter, more plentiful flowers in flowering plants and producing better vegetables. - Water-Soluble Powder – Powdered concentrates go further than liquid fertilizers. Simply mix your measured powder with water and you are ready to feed with multiple gallons of liquid fertilizer! - Micronutrients - Added micronutrients supply your plant with the nutrition it needs for optimal growth and health. Unlike other fertilizers, additional feeding is not required. - Continuous Liquid Feed Program – Intended for use with hydroponic systems. Mixing instructions by volume included. - Fertilizer appearance may vary in color due to variation in raw material size and tracer dye distribution upon the particles in the bag. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07RL8PS24 | | Application Method | Water-Soluble | | Best Sellers Rank | #82,017 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #1,695 in Garden Fertilizers | | Brand | Jack's Classic | | Brand Name | Jack's Classic | | Coverage | 25 | | Customer Reviews | 4.7 out of 5 stars 421 Reviews | | Item Form | Powder | | Item Highlight | Powdered Plant Food, Targeted Micronutrient Package, Increases Bloom Color & Quantity, Liquid Root & Foliar Feeding | | Item Weight | 25 pounds | | Manufacturer | JR Peters | | Mixing Ratio | [E1] 1:3:2 | | Model Number | 77160 | | Number of Items | 2 | | Number of Packs | 2 | | Part Number | 77160 | | Specific Uses For Product | Produce More Flowers | | Target Species | plants, flowers | | UPC | 647941554485 | | Unit Count | 800 Ounce | ## Product Details - **Brand:** Jack's Classic - **Item Form:** Powder - **Item Weight:** 25 pounds - **Number of Packs:** 2 - **Specific Uses For Product:** Produce More Flowers ## Images ![Blossom Booster Water-Soluble Fertilizer, 25lb (2 Pack) - Image 1](https://m.media-amazon.com/images/I/71fHnm9IvcL.jpg) ## Available Options This product comes in different **Number Of Items** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Switched From All Organic, Will Never Go Back *by J***E on August 21, 2020* I've been using the JR brand fertilizers now for three years.
