Best flower fertilizer I ever used!! Been using it for 5 years. Results are amazing!! I use once a week
I use Jacks both bloom booster and general. I like that I ca dissolve it and know it is getting into soil. And I can honestly say my peppers, tomatoes, figs and other plants have shown excellent results.
Excellent product. Very fast shipping!! Will never use anything but Jack's Classic Bloom Booster again. My flowers are WOW!!!!!!
This truly gets results. The tomatoes and eggplant this year are producing like never before. The blooms on my flowers are so full as well. Great Product!!
Bam bam bam!!!! We used it on some petunias and it's hard the see the foliage through the flowers!!! BaM!!!!
This stuff is MAGIC! We'll be ordering more.
Just started using the Jacks Blossom Booster and already noticing a difference in blooms on my hanging basket. Thanks!!!
Best Fertilizer I use ...
Jack's is the best fertilizer I use - and I use it for all of my Clematis vines and my Roses. It works very well.
Very good product fast shipping
I have used Jack's before, but had another name brand that I wanted to use up, and it started burning my flowers! I then order Jack's from here, and put one feeding on. Within a week, the flowers have come out of the burnt stage and are looking great! I will not use anything but Jack's from now on.
Finally, Some Flowers
After three years I finally got my Trumpet Vine to produce flowers by using Jack's Classic Blossom Booster 10-30-20. Great stuff!My plant is in a large pot on my terrace, 11 stories above the bustling NYC traffic. It seems that 10-30-20 is just the right combination.
It's in the results
Been using this for years. First time used on fig plants produced by best crop ever.
Even in the short time of using this product I can see a major difference in flowering and blossoms on my vegetable plants. I use this weekly at 1 tbsp. per gallon of water very impressed so far.
10-30-20 & 20-20-20 fertilizer
I have been using Peters 20-20-20 for years and still do. Now I have tried the 10-30-20 Blossom Booster formula and it too is terrific. Sure glad I can still buy this stuff!The shipment was delivered promptly and my overall experience was great!
Wish I could get this product locally. I get the best performance from Jack's.
This is the best fertilizer I ever have. My roses loves it.
Best fertilizer ever. I cannot believe the results. Just amazing.And Greenhouse Megastore delivery was outstanding also.
Jack's fertilzers are great. I especially like them because they are wate soluble and I have more certainty they rae getting into the plant. I have done comparisons and I can see the results from this fertilizer.
Great service and product. I've used them before and I will use them again
I've used this product for 4-weeks now. It's wonderful. Can't say enough about it.
this is the best
I am very happy with my purchase. Buying bulk fertilizer online is a better deal than buying at the store. Thanks.
I have now used Jack's Blossom Booster for a couple of weeks via the drip irrigation systems I use in the garden and numerous flower beds. I've already noticed a marked improvement in the health of all plants.
You Kidding Me?
Many blue box store brands are ok, if you just want mild performance from your flowers. Buy it use it and be happy you never have to buy blue box store plant food.

Jack Blossom Booster is perfect for all flowering plants. I mix in a five gallon bucket and hit everything that blooms...roses, butterfly bush, fruit trees, peony...everything.
1. Have you ever played POKER? Opening hand usually is Jacks or Better....well, that's card playing.....when it comes to a water soluble fertilizer JACKS ARE BETTER. 2. Take it from me - I'm reviewing as much as I can today, New Year's Day, because this online seller deserves my feedback. 3. I'm using Jacks 10-30-20 every two weeks on my vegetable and flower patio plants. The ease with which this fertilizer combines with ordinary tap water is instantaneous - no residue, the blend of fertilizer and H2O is a marriage and when applied to the plants and leaves, well, my uploaded photos should prove how much vegetation loves this product. 4. I myself am totally amazed at the adaptability of this fertilizer and my plants' needs to be nourished. Seven of my plants are Tomato Hybrids, shouldn't grow any higher than 24 inches, yet, from seed starting on October 15th until now, New Year's Day - these plants are over 4 feet tall. Each plant shows blossoms which are all producing Baby Tomatoes.....well, what more can I say, LIFE BEGINS....LIFE GROWS....LIFE GOES ON....this is truly a family oriented hobby, kids will love this, as well as you Adults. JACKS does everything it's supposed to.....and MORE. A winning hand.....for sure. JACKS.....ARE BETTER!
