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...

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...

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...

Strawberries & Berries
Complete nutrition for strawberries, blueberries, raspberries, and bramble fruits — crops that reward the right fertility program with visibly sweeter, heavier harvests. Strawberry Fertilizer 8-12-32 delivers the high-potassium profile berries want through fruiting, while the acid-loving members of the family (blueberries especially) draw on Elemental Sulfur, Cottonseed Meal, and Ferrous Sulfate to hold soil pH in their preferred range. Boron matters more for berries than almost any other gar...

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...

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...
-
Citrus & Fruit Trees
Complete nutrition for citrus, avocado, stone fruit, and orchard trees — from the balanced seasonal feeding that drives fruit production to the micronutrient corrections trees signal through their leaves. Citrus & Avocado Fertilizer 14-6-4 anchors the program with the nitrogen-forward ratio these evergreen producers want, while the chelated micronutrient line handles what trees are famous for running short on: iron for the pale, yellowing new growth of chlorosis, zinc for small-leaf roset...

Azaleas & Acid-Lovers
Specialized nutrition for azaleas, camellias, rhododendrons, hydrangeas, gardenias, and blueberries — the acid-loving plants that struggle in ordinary soil no matter how much fertilizer they're given. These plants need their soil chemistry managed first: below pH 6, their roots can actually take up iron and the nutrients around them. Azalea & Camellia 15-5-15 delivers the complete feeding program in one formula, while Elemental Sulfur, Cottonseed Meal, and Ferrous Sulfate bring pH dow...

Houseplants & Indoor
Clean, precise nutrition for houseplants, indoor citrus, and container gardens — sized and formulated for pots, not fields. Container plants live in a closed system: nutrients deplete, salts accumulate, and deficiencies show fast in a monstera or ficus that can't reach fresh soil. All-Purpose Houseplant Food 21-7-14 delivers the classic 3-1-2 foliage ratio at measured indoor strength, while Chelated Iron corrects the pale, yellowing leaves common in indoor citrus and acid-loving houseplan...
