Jack's Professional® 10-30-20 Blossom Booster Water-Soluble Fertilizer, 25 lb Bag

Easy-to-use water-soluble mix has a high phosphorus formulation ideal for periods of bud set to greatly increase the number and size of blossoms. Fantastic for vegetables!

A professional grade, water-soluble fertilizer rich in phosphorus to greatly increase the number of blossoms (great for flowers AND vegetables!), and the size of those flowers (for an even better floral display!). This enhanced formulation dissolves faster and cakes less than other top brands. That means it will more effectively feed your plants. Plus, it's chelated for improved plant performance.

Includes an effective blue color tracer so you quickly know exactly where you've sprayed or used it. Available in easy-to-handle 25 lb bags.

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.
