Espoma Citrus-Tone is an organic granular fertilizer with an NPK of 5-2-6, blended for citrus, avocado, and other fruit and nut trees. It carries humates and Bio-tone beneficial microbes, which the brand says speed establishment and support deeper roots. The three-per-year schedule (pre-bloom, post-bloom, fall) is the main draw for container and yard growers. Against synthetic citrus foods it is slower and gentler, and it will not burn or leach away as fast; the trade-off is a lower nitrogen number, so heavy feeders may need more frequent applications. Owners rate it highly, with most praise going to results on potted citrus and the absence of a harsh chemical smell.

Buyers rate Citrus-Tone highly and mostly report healthy growth and good fruit set on potted and yard citrus. Complaints are few and tend to center on the measuring work and slow visible results compared with synthetic feeds.
Espoma Organic Citrus-Tone 5-2-6 is a plant food for citrus, avocado, fruit and nut trees. It is a blend of natural and organic ingredients with humates and beneficial microbes. It is made with no sludges or fillers.
The formula includes Bio-tone beneficial microbes, which promote fast establishment, deeper roots and better blooms. It is made to give long-lasting results without burning or leaching away.
For new plantings, dig a hole twice as wide and the same depth as the root ball. Remove 1/3 of the soil and replace it with compost, peat moss or a good planting mix. Mix 1 cup of Citrus-tone into the amended soil. For established plants, spread it evenly around the outer edge of the tree branches and mix it into the soil. Do not apply it within 6 inches of the trunk.
