I used this on all of the vegetables growing in my garden this year and it worked so well! I used it on zucchini, cucumber, beefsteak tomatoes, bell pepper, and cherry tomato plants. They all grew really well and stayed green and healthy. It's very easy to use, and it even comes with a little measuring scoop. You scoop the amount necessary for your watering can size, fill with water, and give it a little mix. Then, just pour it into your plants as you normally would. The mix doesn't really have much of a smell, but it visually appears a bit blue from the ingredients. It's a really good value for the money in comparison to other garden fertilizers, and the brand is trust worthy. I will keep purchasing this every year for my veggies!

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. For all of my nightshades and peppers, 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. The Tomato Feed is expensive, at least compared to their other products! But, you don't have to use it for the entire season. I only ever use it for the first two fertilizer applications. If I start to notice magnesium or calcium deficiencies later in the season, I reapply. Otherwise, don't use this stuff every day or you'll go broke! Use the all purpose or bloom booster as a regular, more affordable fert for the rest of the season. I get about 2-3 years from one of these buckets and that grows a lot of tomatoes! 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 can't recommend this stuff enough, honestly!
