Review: “Winston” LOVES Jack’s Bloom Booster! - This stuff is AMAZING. This is the only stuff I use on my Royal Poinciana. He throw so many blooms & has bloomed so much earlier than other trees in my neighborhood. He also gets so lush with green way before and way more than the others. I cannot recommend this enough.
Review: Growers must have - This stuff works. Plants produce more blooms with better color after a few uses. Mixes easily and feeds consistently. Great for flowers that need a boost.

## Questions & Answers

**Q: What would be the correct amount to put in an old 1 lb miracle grow hose end sprayer?  1 lb of Jack's as with miracle gro amount of granules?**
A: Yes I believe that is correct. My bucket says 1 tablespoon per gallon of water. Hope that helps!

**Q: Can this fertilizer be used for edilbles like tomatoes?**
A: Yes, you can use this for edibles. It is my favorite for broccoli. I'm assuming you're concerned with toxicity to humans. It is strictly a fertilizer and has no pesticides or herbicides. Also, the nitrogen content is low enough so that it would not produce the excess foliage in tomato plants as could be a problem with a fertilizer with a higher nitrogen percentage. For plants like lettuce that are eaten for their leaves a fertilizer with more nitrogen would be closer to ideal or slightly more economical. I think the only reason that this fertilizer cannot bear the OMRI organic seal is that it uses a chelating agent called EDTA to enhance the absorption of some minerals. EDTA is also used in toothpaste, cosmetics, as a food preservative, and in EDTA therapy. Unless you are trying to get certified as an organic grower, I see not reason not to use Jack's.

**Q: Is this 4lb, or 1lb?  the bucket shows 4lb, but the description says 1lb??**
A: Good question. I was wondering the exact same thing. However, if you add it to your cart I see it shows 4 lbs. So it should be a 4 lbs container.

**Q: How many pounds in the package?**
A: Yes, it is four pounds. I have also bought a 25-lb bag from A. M. Leonard, but the shipping cost almost as much as the fertilizer. If you have a lot of plants or a fair sized garden, buying bigger could save some money. Also, as long as Jack's continues to use potassium sulfate as the potassium source it will be one of my preferred all purpose fertilizers. Similar products use much cheaper potassium chloride as their potassium source and that will degrade the taste of some vegetables.

### ⭐⭐⭐⭐⭐ “Winston” LOVES Jack’s Bloom Booster!
*by L***N on April 17, 2026*

This stuff is AMAZING. This is the only stuff I use on my Royal Poinciana. He throw so many blooms & has bloomed so much earlier than other trees in my neighborhood. He also gets so lush with green way before and way more than the others. I cannot recommend this enough.

### ⭐⭐⭐⭐⭐ MAGIC POWDER!!
*by L***N on June 11, 2024*

I have always killed every single plant I buy in the summer every year! I can’t keep anything alive let alone have flowers! Well everything changed when I bought Jacks Blossom Booster! This stuff has taken me from dead flowers to new blooms and beautiful flowers everywhere! The beautiful hanging petunias I buy every year and kill every year are now bursting with flowers after only one use!! It comes in a powder form with a little scooper. Just measure the amount of water needed, scoop the powder and add to the water. I like to let it sit and dissolve in the water for a few minutes and stir it around to make sure the product doesn’t get wasted. Tip: When watering with the fertilizer add little amount to the soil at a time or else all the fertilizer water will go through at once and get wasted! Little slow amounts to let the plant absorb it all the way is key! Overall I will definitely be buying more of Jacks fertilizer in the future to help my flowers and my garden bloom all summer long!
