Schultz Liquid Plant Food is an all-purpose liquid plant food for indoor and outdoor plants, designed to encourage new growth and provide balanced everyday plant nutrition.
This concentrated liquid fertilizer is made to support a wide range of plant types, including flowers and vegetables, so you can keep one dependable all-purpose plant nutrient on hand for mixed collections. When you want consistent results without switching products between the windowsill and the garden, Schultz Liquid Plant Food fits that role as a simple, go-to liquid plant food concentrate.
The formula is described as micronutrient-rich, giving plants more than just basic macronutrients. Alongside its primary nutrients, it includes chelated micronutrients such as iron, manganese, and zinc, which help round out nutrition for steady, healthy-looking growth. The product is also pH neutral, a helpful attribute for growers who prefer a plant food that stays straightforward and predictable in day-to-day care.
Schultz Liquid Plant Food is a 10-15-10 NPK plant food, built around core inputs derived from urea, ammonium and potassium phosphates, and potassium nitrate. That combination supports general-purpose nutrition aimed at maintaining vigorous growth and keeping plants performing well across active growing periods. It’s a practical fit when you want a concentrated liquid plant food that can support leafy growth while also backing strong overall plant performance in flowering and productive gardens.
For convenience, it comes with an easy-to-measure dropper, keeping the product approachable for both new plant owners and long-time gardeners who value consistency. As a liquid plant food concentrate with micronutrients, Schultz Liquid Plant Food is well suited for growers who want a simple all-purpose liquid fertilizer for indoor and outdoor plants, including flowers and vegetables, with a clean, no-fuss focus on encouraging new growth.
| Total Nitrogen (N) | 10.0% |
|---|---|
| Available Phosphoric Acid (P2O5) | 15.0% |
| Soluble Potash (K2O) | 10.0% |
| Chelated Iron (Fe) | 0.1% |
| Chelated Manganese (Mn) | 0.05% |
| Chelated Zinc (Zn) | 0.05% |
| EDTA (Chelating Agent) | 1.01% |
Available phosphoric acid provides a fast-absorbing form of phosphorus that fuels root growth, energy transfer, and strong flowering. It becomes part of the plant’s total available phosphate supply, but the two terms are not the same—available phosphoric acid is one source of phosphorus, while available phosphate refers to the entire pool of plant-available phosphorus overall.
Chelated iron is important because it keeps iron usable for plants even when growing conditions would normally lock iron out, helping prevent the classic yellow-new-leaf symptom caused by low chlorophyll production. It is unique from other iron sources because the chelation protects iron from becoming insoluble, making it a more reliable way to correct iron-related chlorosis when regular iron can fail.
Chelated manganese is important because it keeps manganese available for photosynthesis and enzyme activity even when pH or water chemistry would normally lock it out, and it’s unique from similar micronutrients because it strongly supports the plant’s energy-processing systems that drive healthy, resilient new growth.
Chelated zinc is important because it keeps zinc available for uptake even when pH or root-zone conditions would normally lock zinc out, helping plants form normal-sized, healthy new growth—something that makes zinc uniquely different from many other nutrients that mainly affect older leaves or simple leaf color changes.
EDTA chelation is important because it helps key micronutrients stay dissolved and available for roots instead of reacting, precipitating, or becoming locked out, which prevents common deficiency symptoms like pale new growth. It’s unique because it offers dependable micronutrient stability in mildly acidic growing conditions, making it especially useful for consistent feeding when pH is already well-managed.
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.
