Why do Florida fruit trees often show yellowing leaves?

Nutrient deficiencies, including micronutrient deficiencies, are commonly discussed causes in sandy Florida soils, though yellowing can have several causes. Local extension guidance is the best way to confirm a diagnosis.

Is citrus fertilizer suitable for other fruit trees?

Products labelled for citrus are often used more broadly in Florida because of their micronutrient content, but you should follow the label directions for the plants listed.

Are there restrictions on when I can fertilize?

Yes, many Florida local governments restrict fertilizer use during the summer rainy season. Requirements vary, so check your county or city rules.

Fertilizer questions come up constantly in Florida because sandy soil holds very few nutrients. Water moves through it quickly, and dissolved nutrients move with it. That is why slow release products and micronutrient content get so much attention here.

Many Florida counties and cities restrict fertilizer application during the summer rainy season to protect water quality. Check your local ordinance before applying, because the rules differ by location.

This buying guide is being written to compare fertilizer types by the job they do. The planned structure is listed below.
