As a member and officer of the Crescent City Fuchsia Society we look for the best all around fertilizer for growing fuchsias and bringing them into peak bloom. Jack's 20-20-20 formula fills the bill completely and is in fact the best water soluable fertilizer we have found.

5 Stars Great Product

My father used this type of product in his greenhouses. I have tried to purchase locally, just had to buy on-line. I use this fertilizer for watering seedlings and bucket feeding house plants around the house. This fertilizer works great in the E-Z Flo automatic fertilizing jug for fertilizing my garden. It is very easy to use and it dissolves quickly. I will be ordering more from this vendor, cheapest I could find for the home owner. Thanks for selling to the little guys.

I have been using Jack's and or its former name since 1981 and have found nothing compares for my very exacting expectation. It's simply the best!

5 Stars Jacks works great in Florida

Having moved to Florida in 2003, we found that dry fertilizer wasn't doing the job because of our climate, and dry seasons. Jacks goes on our flowers and bushes twice per month and we have had excellent results during the last 6 years of using this product.

5 Stars Excellent general purpose fertilizer

We use this fertilizer in our water truck when watering the container gardens and flowerbeds around the city........we have had excellent results year after year. We receive numerous compliments on our plantings and Jack's makes a huge impact, with more blooms, healthier plants and attractive containers.
