Because their nitrogen is water soluble, most liquid fertilizers are quick-acting sybthetic products. Their nitrogen is available to plants almost immediately, and therefore tends to be in strong doses. Because it is taken up by plants promptly its effect lasts only a couple of weeks. To sustain consistent levels of available nitrogen, liquid fertilizers must be used several times over the growing season.
THEREFORE WE RECOMMEND USING ONLY NATURAL ORGANIC LIQUID FERTILIZER PRODUCTS.
While you can pour organic liquid fertilizers directly onto the soil as a drench, they are best used as foliar, or foliage, sprays. Leaf tissues can absorb the nutrients directly and quickly. Use orlganic liquid fertilizers during the growing season to supplement the granular main meal to boost the energy of plants that produce fruit and flowers steadily over the whole season such as tomatoes and annual flowers such as petunias and impatiens. Use very dilute solutions of organic liquid fertilizer when you water houseplants to maintain their vigor.
