Our take on the Citrus Mix Fertilizer 6-3-3 (5 lb)

Citrus Mix 6-3-3 is a granular organic-based fertilizer built around citrus, with a moderate nitrogen level for leaf and shoot growth, phosphorus for bloom, and potassium for fruit fill. It adds micronutrients and is made from feather meal, fish bone meal, alfalfa meal, kelp meal, basalt and potassium sulfate, so it feeds soil life as well as the tree. The 5 lb bag suits container citrus, small home orchards and repeat applications through the growing season. Against synthetic citrus spikes and high-nitrogen lawn-type fertilizers, it is gentler and more complete, but it releases slowly and needs more frequent dosing. Buyers rate it highly, though the feedback base is small.

About the Citrus Mix Fertilizer 6-3-3 (5 lb)

Citrus Mix Fertilizer 6-3-3 is a plant food for citrus trees, including those in home orchards and containers. It can also be used on avocados, other fruit trees, ornamentals and vines. The 6-3-3 NPK formula supplies nitrogen for green growth, phosphorus for flowering and potassium for fruit development. It also contains micronutrients.

The fertilizer is made from natural and organic materials: feather meal, fish bone meal, alfalfa meal, basalt, kelp meal and potassium sulfate.

For established citrus trees, apply 1 cup per inch of trunk diameter. Spread it from the base out to the drip line, work it into the soil and water thoroughly. When planting a new tree, mix 1 cup into the backfill soil. Trees that are 1 to 2 years old get half the recommended amount. For container citrus, apply 2 to 4 tablespoons per gallon of soil, 4 to 6 times per year.

Questions and answers

Is this fertilizer good for potted citrus?
Yes. It is suited to container-grown citrus, and the granular form works into potting soil. Water it in well after applying and keep to the trunk-diameter dose so salts do not build up.
How does it compare with citrus fertilizer spikes?
It spreads around the drip line rather than being driven into the soil, so it covers the feeder-root zone more evenly. It also lists micronutrients and organic meals, which most spikes do not.
Can I use it on avocados and other fruit trees?
Yes. The label lists avocados, fruit trees, ornamentals and vines. Use the same trunk-diameter rate and water it in.
Does it contain iron or other micronutrients?
It is described as enhanced with micronutrients and includes kelp meal and basalt. It does not list a chelated iron percentage, so yellowing leaves from high-pH soil may still need a separate iron treatment.
When should I apply it?
Feed at the start of the growing season and repeat through spring and summer for containers. Avoid heavy applications in winter when growth slows.
What is in the bag?
A 5 lb bag of 6-3-3 granular fertilizer made from feather meal, fish bone meal, alfalfa meal, basalt, kelp meal and potassium sulfate.
