House & Garden’s Nitrogen Boost provides plants with the additional levels of nitrogen they need for rapid growth. Nitrogen Boost is carefully formulated to deliver a safe, high-quality form of nitrogen to your plants while promoting bigger yields, tastier vegetables, and a crop that is more resistant to pests, diseases, and adverse conditions.
Nitrogen Boost should be used only during the vegetative stage of growth, starting with 1 ml per gallon on younger plants and progressing upwards to 2 ml per gallon by the end of the vegetative stage. For aggressive plants, these amounts can be doubled (starting with 2 ml and ending with 4 ml), but plants may grow too rapidly when supplied with excessive amounts of nitrogen, causing them to develop protoplasm faster than they can build sufficient supporting material in cell walls. Such plants are often rather weak and may be more susceptible to attacks by diseases and pests.
Nitrogen Boost is extremely concentrated and overuse can also burn plants and damage leaves. Immediately flush plants at the first sign of nitrogen toxicity.
