Organic Fertilizers
Organic fertilizers that feed your plants and support healthier soil Organic fertilizers do more than supply nutrients. They also help support soil biology, build organic matter, and improve soil structure over time — creating a growing environment that can improve season after season. Because nutrients are released gradually as materials break down, organic fertilizers often provide a steadier feeding pattern with less burn risk than fast-acting synthetic options. Whether you're...

Hydroponics Nutrients
Hydroponic growing gives you precise control over every nutrient your plants receive — but that precision only works if you start with the right fertilizers.

Water-soluble fertilizers for soil, hydroponics, foliar spray, and drip irrigation Water-soluble fertilizers dissolve completely in water and are designed for direct delivery to plant roots or leaves — without waiting for soil microbial breakdown. Whether you're looking for a water-soluble fertilizer for vegetables, a complete nutrient program for hydroponics, a foliar spray to correct a deficiency mid-season, or a reliable fertigation product for drip irrigation, every product in this...

Nitrogen Fertilizers
Nitrogen is the single most important nutrient for plant growth — it drives chlorophyll production, protein synthesis, and vigorous vegetative development. When nitrogen is deficient, plants yellow from the oldest leaves upward, growth stalls, and yields drop. The right nitrogen fertilizer, applied at the right time, is one of the fastest and most visible improvements you can make to any garden, lawn, or crop. Greenway Biotech offers nitrogen fertilizers for every growing method and goal — f...

Chelated Fertilizers
Correct micronutrient deficiencies fast — chelated iron, zinc, manganese & copper Chelated fertilizers help keep iron, zinc, manganese, and copper soluble and available to plants — especially in neutral to alkaline soils where these micronutrients become tied up and difficult for roots to absorb. In high-pH conditions, chelated forms can significantly improve availability compared to non-chelated sulfate alternatives. Greenway Biotech chelated micronutrients are water-soluble and...

Tomatoes & Vegetables
Fertilizers for tomatoes, peppers, eggplant, squash, and every fruiting vegetable in your garden or hydroponic system. Fruiting crops carry heavy nutrient demands: phosphorus for root establishment and fruit set, high potassium through ripening, and steady calcium and magnesium to prevent blossom end rot. This collection pairs our crop-specific Tomato Fertilizer 4-18-38 with the supporting nutrients a complete program needs — Calcium Nitrate, Cal-Mag Plus, Epsom Salt, and chelated micronutrie...

Roses & Flowers
Bloom-building nutrition for roses, dahlias, peonies, annuals, and every flowering plant where the payoff is the display itself. Flowers respond to phosphorus-forward feeding — it drives root establishment, bud count, and bloom size — which is why Rose & Flower 4-7-5 and Blossom Green 2-6-8 anchor this collection alongside the classic organic bloom builders: Bone Meal, Fish Bone Meal, and Alfalfa Meal, the amendment rose growers have sworn by for generations. Epsom Salt supplies the magne...
-
Lettuce & Leafy Greens
Nitrogen-forward nutrition for lettuce, kale, spinach, chard, and every leafy crop where the harvest is the foliage itself. Leafy greens want steady available nitrogen, adequate calcium to prevent tip burn, and magnesium for deep leaf color — without the heavy phosphorus and potassium that fruiting formulas carry. This collection centers on Lettuce Fertilizer 8-15-36 for hydroponic and soil programs, backed by Calcium Nitrate and Cal-Mag Plus for tip burn prevention, and fast organic nitrogen...
-
Pepper & Herbs
Balanced, potassium-rich nutrition for peppers, basil, cilantro, and culinary herbs. Peppers set more fruit and ripen with stronger flavor when potassium stays high through the season, while herbs respond to moderate, even feeding that builds oil content without forcing weak growth. Pepper and Herb Fertilizer 11-11-40 anchors this collection with a full chelated micronutrient package, supported by Calcium Nitrate for structure, Epsom Salt for magnesium, and Monopotassium Phosphate for bloom a...
-
Cucumbers & Vines
High-potassium feeding programs for cucumbers, zucchini, melons, and every vining crop that sets fruit fast and keeps producing. Vine crops are heavy feeders with a distinctive preference: they're chloride-sensitive, which is why this collection leans on Potassium Sulfate and Sulfate of Potash Magnesia rather than muriate sources. Cucumber Fertilizer 8-16-36 anchors the program with chelated micronutrients for soil, foliar, and hydroponic use, while Calcium Nitrate and Epsom Salt keep cal...
-
Palms & Tropicals
Purpose-built nutrition for palms, bananas, birds of paradise, and tropical ornamentals — indoors and out. Palms have the most distinctive nutrient profile in the landscape: they are famously hungry for magnesium and manganese, and the yellowing older fronds and frizzled new growth that plague palms are almost always those two deficiencies, not disease. Our Palm Tree Fertilizer delivers the complete program, supported by Epsom Salt and Sulfate of Potash Magnesia for magnesium, Manganese Sulfa...
