Liquid Organic Fertilizers
Plants can absorb liquid fertilizers through both their roots and through leaf pores. Foliar feeding can supply nutrients when they are lacking or unavailable in the soil. It is especially effective for giving fast-growing plants like vegetables an extra boost during the growing season. Some foliar fertilizers, such as liquid seaweed, are rich in micronutrients and growth hormones. These foliar sprays also appear to act as catalysts and increase nutrient uptake by plants.
