Used it to grow the sweetest watermelons and cantaloupes I ever raised here in sw Arkansas.
I used Jack's Pro Water Soluble, on a weekly basis, all summer. My potted plants were healthy and I had continuous blossoming right up to the first frost. I also used Jack's on my inground plants and flowers. They grew large and lush. My garden was beautiful and we rec'd lots of compliments on it. I will definitely use Jack's Pro from now on!!
I'm a home gardener who grows mostly vegetables, berries & flowers. I like Jack's water soluble fertilizers because they work well, are available in a large (25 lb.) size and are moderately priced, including the $5 shipping. They work for both foliar feeding & as a soil drench. In most of my beds I use black fabric mulch along with wood chips, so it's much easier to apply than granular fertilizers. I use the blossom booster, but also Jack's 20-20-20, sometimes in combination, as recommended on their website.
