The application of diluted liquid nutrients directly to plant leaves, allowing certain nutrients to be absorbed through the leaf surface.
Most plant nutrients are absorbed through roots, but some nutrients can also enter through leaves when applied as a liquid spray. This method is known as foliar feeding.
Because nutrients are applied directly to the plant, foliar feeding can provide faster results than some soil-based applications. It is commonly used to supplement regular fertilization, address specific nutrient deficiencies, or support plants during periods of active growth.
While useful, foliar feeding is generally not a substitute for healthy soil and proper fertilization practices.
Foliar feeding can help deliver nutrients quickly when plants need immediate support. It is particularly valuable for correcting certain micronutrient deficiencies, supporting container-grown plants, and supplementing routine fertilization programs during the growing season.
