House & Garden Magic Green, 20 L

Foliar Spray for Fast Macronutrient Uptake, 20 L

When root uptake slows down, whether from stress, cool media, or a temporary feeding gap, foliage can turn pale or yellow well before a root-applied correction takes effect. Magic Green is a foliar spray formulated to deliver key macronutrients directly through the leaf surface, giving growers a faster path to correcting visible deficiency symptoms, sized at 20 L.

This 20 L size is built for a commercial operation running foliar treatments across a larger number of plants or benches on a routine basis.

Key Features & Benefits

• Foliar Application — Delivers macronutrients directly through the leaf surface rather than through the root zone.
• Targets Yellowing Leaves — Helps restore color to foliage that has turned pale or yellow.
• Fast-Acting — Improvement is often noticeable within a day of application.
• Supplements Root Uptake — Useful when root-based nutrient absorption is not keeping pace with the plant's needs.

Who Should Use Magic Green

Growers noticing yellowing leaves or slow nutrient uptake through the root system will find this foliar spray useful as a supplemental feeding method alongside their regular nutrient program.

Frequently Asked Questions

How is Magic Green applied?

Magic Green is applied as a foliar spray directly onto the leaves rather than mixed into the root-zone feeding solution. Coating the foliage evenly gives the macronutrients the most surface area to be absorbed.

What problem does Magic Green address?

It is formulated to address yellowing leaves caused by insufficient nutrient uptake through the roots. Because it bypasses the root system, it can correct visible symptoms faster than a root-applied adjustment alone.

How quickly does Magic Green work?

Growers often see noticeable improvement in leaf color within a day of application. Results can vary depending on the severity of the underlying deficiency.

Does Magic Green replace root feeding?

No, Magic Green supplements root uptake rather than replacing it. Keep running your regular base nutrient program and use Magic Green as a targeted foliar correction when needed.

When is the best time to spray Magic Green?

Apply it when foliage shows visible yellowing or when root uptake appears to be lagging, rather than as a routine preventive spray. Spraying during cooler, lower-light periods of the day helps reduce the chance of leaf stress from the application.
