Fertilizer Guidance for Vanilla Production in Florida

Vanilla has a three-to-five-year, pre-productive period, during which consistent and well-targeted nutrient management is essential for vigorous vine growth, successful flowering, and pod development. Organic substrates commonly used in Florida container production systems often lack sufficient nutrients, making systematic fertilization essential throughout the crop cycle. This publication provides research-based fertilizer guidance for commercial vanilla growers. Controlled studies indicate that optimal nitrogen supply falls within a range of 13–21 g N per plant per year, supporting vegetative growth without excessive nutrient accumulation. This publication includes annual NPK rates for young plants, leaf tissue nutrient concentrations by growth stage, appropriate fertilizer sources, and application methods for container and field systems. It also provides complementary practices on irrigation, substrate pH, and humidity management.
