House & Garden Magic Green is a foliar spray nutrient designed to deliver crucial macronutrients through the leaf surface to support overall plant vitality. It’s a foliar nutrient spray and plant nutrient additive made for fast canopy support when root uptake is not keeping pace.
Magic Green is built around fast foliar nutrient delivery, helping plants respond quickly when leaves show signs of stress or yellowing. It’s positioned to green up yellowing leaves with noticeable improvement that can appear overnight, while also supporting foliage through its role as a leaf strengthener. That combination makes it useful when you want quicker visible recovery in the canopy without changing the base nutrition you already rely on.
Beyond rapid greening, Magic Green is intended to strengthen and support foliage across the full life cycle. It’s described as boosting plant vigor at any stage, with a practical focus on maintaining healthier-looking leaves and steadier growth momentum. When leaf discoloration is linked to macronutrient deficiencies, Magic Green is positioned to help alleviate that discoloration by supplying those macronutrients directly to the foliage.
Magic Green has an NPK of 0.3-0.1-0.4, presented as a compact nutrient profile for foliar canopy support. Its listed inputs are ammonium nitrate, nitric acid, potassium oxide, and phosphoric acid, keeping the formula centered on soluble nutrient sources rather than a long list of extras. It contains no dyes, no synthetic PGRs, and no detectable heavy metals, which matters for growers who prefer a clean-input foliar nutrient option.
It’s suitable for hydroponics, coco, and soil, and it works in all growing media. House & Garden positions it for vegetative growth and early bloom, making it a straightforward choice when plants need a quick foliage-focused nutrient boost during active development.
House & Garden Magic Green is a good fit for growers who want a foliar spray that supports fast foliar nutrient delivery, greens up yellowing leaves, and strengthens foliage, while keeping the nutrient program simple across common media and systems.
Step-by-step mixing and feeding instructions for House & Garden Magic Green - 1 Litre.
Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of House & Garden Magic Green - 1 Litre well before every use. Using the feeding schedule below, measure the recommended dose and add it directly to the water while stirring. Allow the solution to mix fully before adding any other fertilizers, additives, or supplements.
Always add nutrients to water — not the other way around. Mix thoroughly between products to ensure an even, stable nutrient solution.

Warning – Important Safety Information
This product may cause mild skin irritation and eye irritation. Avoid unnecessary contact with skin, eyes, and clothing. Use only as directed.
General safety precautions
Read and follow all instructions on the product label and any accompanying documentation before use. Keep out of reach of children and pets. Do not ingest. Avoid breathing vapours, mist, or dust that may be generated during handling or use.
Wear appropriate personal protective equipment (PPE), such as protective gloves, long sleeves, long pants and closed-toe footwear. When there is a risk of splashing or airborne particles, use safety glasses or other suitable eye and face protection.
First aid – skin contact
IF ON SKIN OR HAIR: Remove contaminated clothing immediately. Rinse skin with clean water for several minutes, then wash with mild soap and water. If irritation or redness develops and persists, seek medical attention. Wash contaminated clothing before reuse.
First aid – eye contact
IF IN EYES: Rinse cautiously with clean water for several minutes, keeping eyelids open. Remove contact lenses if present and easy to do. Continue rinsing. If irritation persists, obtain medical advice.
First aid – ingestion and inhalation
IF SWALLOWED: Rinse mouth thoroughly with water. Do not induce vomiting unless instructed by a medical professional. Seek medical attention if you feel unwell.
IF INHALED: Move the person to fresh air and keep them comfortable for breathing. If coughing, breathing difficulty, dizziness or other symptoms occur, seek medical assistance.

| Total Nitrogen (N) | 0.3% |

Ammoniacal Nitrogen (N) is a plant-available form of ammonium (NH₄⁺) that provides a steady, gentle source of nitrogen for healthy green growth. Unlike fast-release nitrogen types, ammoniacal nitrogen feeds plants slowly, helps stabilize root-zone pH, and works well in cooler temperatures. It is commonly used during early vegetative growth because it supports strong leaf development without burning young roots. If plants show pale leaves, slow growth, or weak stems, they may need more available ammoniacal nitrogen.
Ammonium nitrate is unique because it provides nitrogen in two plant-usable forms at once, which can give a fast green-up while still supporting steadier uptake depending on the root-zone conditions. That matters because it can correct true nitrogen shortages quickly, but it also needs careful balance since too much can push overly soft growth and trigger pH drift and nutrient imbalances.
Available Phosphate (P₂O₅) supports root development, energy transfer, and early structural growth by providing a form of phosphorus that plants can absorb and use quickly.
Nitrate Nitrogen provides a stable, easy-to-absorb form of nitrogen that supports steady growth, strong foliage, and reliable plant development without sudden nutrient swings.
Soluble potash (K2O) is important because it helps plants control water use, move sugars to new growth and fruit, and build stronger, higher-quality structure under stress. It’s unique from many other nutrients because it acts more like a regulator and transport helper than a direct “building material,” so the biggest benefits show up as steadier growth, stronger stems, and better finishing instead of just bigger leaves.
Total Nitrogen is important because it directly drives leafy growth, chlorophyll production, and overall growth speed, which sets the pace for the entire plant. It’s unique because the “total” number can include different nitrogen forms that behave differently in the root zone, meaning the same total amount can produce very different results depending on the nitrogen type and plant stage.
Nitric acid lowers pH, but it also adds nitrate nitrogen once diluted, so it can influence both nutrient availability and the plant’s growth balance. That makes it important for stable uptake, and unique compared to acids that adjust pH without contributing nitrate.
Yes, it can if it pushes phosphorus too high or drives pH too low, because both conditions can reduce the plant’s ability to take up key micronutrients and calcium even when they’re present in the feed, which makes phosphoric acid uniquely powerful compared with slower, gentler phosphorus sources.
Potassium oxide (K2O) is important because it shows how much potassium is available to support water control, sugar movement, and strong plant structure, which directly impacts growth quality and stress tolerance. It’s unique because K2O is mainly a label standard for potassium content, not a separate nutrient form the plant absorbs, so understanding it helps you avoid mixing up label numbers with real potassium needs.
