Review: Excellent liquid fertilizer product for home gardeners! - I needed a quality source of liquid fertilizer that I could mix in small quantities for my 2025 growing season of young vegetable transplants. I found the product to be simple to mix and it produced excellent results. It was recommended to me by some local greenhouse plant growers. I liked the size, nutrient balance, and value for the money to be excellent. My plants grew very healthy. I used it on flowers and vegetables.
Review: Literally can't go wrong with Jacks - My garden has never looked so full and healthy till I found d Jack's 20-20-20. I'll never go back to miracle gro. THIS product works and with fruit, veggies and flowers. 10 stars!!!!

## Questions & Answers

**Q: Can you use this for Hoyas or are the numbers too high?**
A: People saying the numbers are too high don't quite know what they're talking about.  It doesn't matter if it's a 20-20-20, 2-2-2, or 80-80-80 as they all have a ratio of 1-1-1.  The only difference is how concentrated each one is and how much of each you use. With a higher 20-20-20 you'd use much less than a 2-2-2. In the end, it's all the same as the ratio is really what's important.

**Q: Does it have magnesium?**
A: 0.05% Chelated Magnesium

**Q: Where are the ingredients derived from, and is it ok to use in an organic garden?**
A: Not 100% sure what its derived from, you would have to call the manufacturer. And this is a "synthetic" chemical fertilizer so it may hurt the organic material thats already in the soil. If your after yield, this fertilizer will blow away any organic fert on the market. If you give your garden a 1-2 week water only diet near the end, your product will not taste anything like chemicals. I have been using it for over decade, and wouldnt use anything else. Its the BEST!!  Good luck :)

**Q: Can I use this fertilizer On a small rooted cutting? Or will it burn its roots ?**
A: Yes. I use this on my newly rooted cutting after potting them up. Make sure that you dilute it. 1/8 to 1/4 teaspoon per gallon of water.

### ⭐⭐⭐⭐⭐ Peters/Jacks The Best
*by T***G on June 25, 2024*

When I was young, my Grandfather introduced me to Peters 20-20-20. He had roses he prized. He used this on his roses, which he would give to friends and neighbors. The roses were huge, healthy and very fragrant. I have used Jacks on my fruits and vegetables, with amazing results. The plants are healthy and the fruits and vegetables beautiful. I use it in a watering can to fertilize the leaves and also to water/fertilize the base of the plant. This is the best fertilizer I have found. Grows award winning plants, and the price point is similar to other sub par fertilizers. Easy to use and mix, and it dissolves almost instantly.
