This is fine to use with other plants too (annuals, perennials, palms, veggies, etc) . Most plant-specific fertilizers are fine to use on other plants it's primarily marketing. Especially on Organics a percentage point here or there won't make much of a difference.

Theres something about this brand fertilizer compared to other organic brands, my avocado and mango produce more and slightly larger fruit, i just move the soil, spread this in the groove then cover with the soil. For fun i also sprinkled some in some sugarcane propagating in water and the speed at which they developed was surprising, placed a little in potted Bougainvillea and Hydrangea and they look healthy and are pushing out lots of blooms. I will test on grapes and strawberries, but this is a winner for me and i used less than directed.

Wondering how is this labeled for citrus, Because citrus likes a lot of nitrogen, you want to purchase a fertilizer with at least a 2-1-1 ratio, or twice as much nitrogen as phosphorus and potassium. This is just opposite with 3-5-5.
