What is all this talk about foliar feeding? The most common method of delivering nutrients to plants is through their roots - by watering or root drench. Foliar feeding, an alternate method, delivers nutrients through the foliage or leaves of plants.
The advantages of foliar feeding are numerous:
Foliar applied nutrients are one hundred to five hundred times more effective than root nutrition.
Foliar applied nutrients are available to your plants immediately, so you see results more quickly.
Foliar applied nutrients can make elements, such as iron, available to plants when they are not available in the soil.
Foliar applied nutrients can successfully reduce the nutritional stress situations of plants.
