Grow More® All-Season's Plant Food 20-20-20 — 1 oz

Balanced All-Season Plant Food with Medium Potential Acidity to Counteract Alkaline Water

Grow More® All-Season’s Plant Food 20-20-20 is a perfectly balanced, 100% water-soluble fertilizer formulated with medium potential acidity — a characteristic specifically chosen to help counteract the effects of moderately alkaline irrigation water that is common in many growing regions. The 20-20-20 NPK ratio makes it a true all-season formula, providing equal parts nitrogen, phosphorus, and potassium that supports healthy, balanced plant growth through every stage of the growing cycle. Versatile for both foliar and soil application and organic compatible.

Key Features & Benefits

• 20-20-20 Balanced NPK: Equal parts nitrogen, phosphorus, and potassium in a single formula — the classic balanced fertilizer ratio that supports vegetative growth, root development, and flowering across the full growing season without requiring stage-specific formula changes.
• Medium Potential Acidity: The acidifying properties of this formula help offset the alkalinity common in municipal tap water and well water in many regions, gradually moving the soil or growing medium toward a more plant-favorable pH range without the need for separate pH correctors.
• Counteracts Alkaline Water: Specifically formulated as a tool for growers dealing with moderately alkaline irrigation water — where the alkalinity of the water itself pushes soil pH up over time, reducing micronutrient availability and plant performance.
• Versatile Application: Can be applied as a foliar spray for rapid nutrient uptake through leaf surfaces, or as a soil drench for root-zone feeding — giving growers flexibility to address different nutritional needs across different growing situations.
• Organic Compatible: Formulated to be compatible with organic growing programs, making it suitable for growers who blend conventional soluble fertilizers with organic inputs in their nutrition programs.

Who Should Use This

All-Season’s Plant Food 20-20-20 is ideal for home gardeners, container plant enthusiasts, and small-scale growers who want a single, easy-to-use balanced fertilizer for all their plants throughout the season. It is particularly valuable for growers in regions with alkaline tap water who want a fertilizer that actively works to counteract the pH-raising effects of their water source.

Compatibility

Compatible with all soil types and container growing media. Apply as a dissolved soil drench or foliar spray at the recommended label rate. The medium potential acidity of the formula makes it particularly effective when used with alkaline water sources. Can be used alongside organic inputs and other nutrient supplements as part of a complete growing program.

Frequently Asked Questions

What does “medium potential acidity” mean in a fertilizer?

Potential acidity refers to the acidifying or alkalizing effect a fertilizer has on soil after it is applied and taken up by plants. Fertilizers containing ammoniacal nitrogen leave an acidic residue as roots take up ammonium and release hydrogen ions in exchange. A medium potential acidity rating means this formula has a moderate acidifying effect — enough to counteract the gradual pH rise caused by alkaline irrigation water without aggressively over-acidifying the growing medium.

How does alkaline irrigation water affect plant nutrition?

Alkaline water raises the pH of soil and growing media over time, reducing the availability of key micronutrients including iron, manganese, zinc, and copper that become insoluble above pH 7.0–7.5. This leads to micronutrient deficiency symptoms — particularly interveinal chlorosis from iron deficiency — even when these nutrients are physically present in the soil. Using a moderately acidifying fertilizer helps maintain a plant-favorable pH range.

Can this product be used year-round?

Yes. The 20-20-20 balanced ratio is formulated for season-long use across all plant types and growth stages. It provides adequate NPK for vegetative growth, root development, and basic flowering support without the extremes of high-nitrogen or high-PK formulas that are better suited to specific growth phases.

What does “organic compatible” mean for this product?

Organic compatible means the formula can be used alongside organic inputs — such as compost, worm castings, kelp meal, and organic liquid fertilizers — without negatively impacting the efficacy of those organic materials. It does not mean the product itself is OMRI certified for certified organic production.

Is this suitable for use in a drip irrigation system?

Yes. The 100% water-soluble formula dissolves completely and is compatible with drip irrigation systems. Mix at the recommended concentration in the irrigation water and apply through the drip system as a standard fertigation application.
