Espoma Citrus-Tone is a granular organic fertilizer for citrus trees and avocados. It blends natural ingredients with Bio-tone microbes, a proprietary mix that Espoma says boosts biological activity around the roots. The formula releases slowly through the growing season and is described as non-burning, so it suits container and in-ground trees alike. Against synthetic citrus foods, it trades fast greening for gentler, longer feeding and soil building; gardeners who want organic inputs tend to prefer it, while those chasing quick results may find it slower.

Growers of potted and in-ground citrus report steady growth and healthy foliage with Citrus-Tone, and many value that it is organic and does not burn roots. Some note it works gradually rather than delivering fast greening.
Espoma Citrus-tone is a plant food for citrus trees and avocados. It is made from natural and organic ingredients and contains no sludges or fillers. The blend is meant to give complete, balanced feeding.
The organic ingredients break down gradually, creating a long-lasting food reservoir through the growing season. It is slow release and won't burn or leach away. It also contains Bio-tone, a proprietary blend of beneficial microbes that enhances the plant food.
For new plantings, dig a hole twice as wide as the root ball and at the same depth. Replace 1/3 of the soil with compost, peat moss, or a good planting mix, then mix in 1 cup of Citrus-tone. For established trees, apply it evenly around the outer edge of the branches and mix it into the soil. Water thoroughly after each application.
