Our take on the Mr. B's Green Trees All Purpose Boost

Mr. B's Green Trees All Purpose Boost is an organic granular all-purpose fertilizer sold in a bucket. It is a balanced 8-8-8 NPK blend meant to feed annuals, perennials, flowers, herbs and fruiting plants in containers, raised beds and in-ground soil. The organic base feeds soil as well as plants, and the fast-acting formula is described as lasting a full season. Against synthetic all-purpose feeds it trades a lower, gentler nutrient dose for soil-friendly organics; against single-ingredient organic products it covers all three major nutrients in one bucket.

Questions and answers

What is the NPK ratio of Mr. B's Green Trees All Purpose Boost?
It is 8-8-8: equal parts nitrogen, phosphorus and potassium. That balanced ratio suits general feeding rather than pushing one type of growth.
Is it really organic?
Yes. The product is listed as organic, built on an organic base rather than synthetic salts.
What plants can I use it on?
Annuals, perennials, flowers, herbs and fruiting plants. It is labeled for containers, raised beds and in-ground soil, indoors and outdoors.
How long does one application last?
The maker describes it as fast-acting with a full-season effect. Organic granular feeds release gradually, so expect steady feeding rather than a quick spike.

It is gentler and soil-friendly but lower strength at 8-8-8, so you use more of it. Synthetics are more concentrated but add no organic matter.

It is packaged in buckets, with an 8 lb size and a larger 40 lb size.
