Supply Solutions | 17-18-18 HumiSync Plant Food Powder | Balanced NPK Fertilizer with Humic Acid for Lawn, Garden, Vegetables, Flowers, Trees & Shrubs - All Purpose Garden Fertilizer - 40lbs

Feed the soil. Fuel the plant.

Supply Solutions 17-18-18 HumiSync is a balanced 17-18-18 plant food designed for gardeners who want dependable, even nutrition across lawns and landscape beds. This 17-18-18 fertilizer delivers equal parts nitrogen, phosphorus, and potassium (NPK) to support root development and steady top growth, while added micronutrients—boron, manganese, and zinc—round out your fertility plan. Humic acids from leonardite act as a soil enhancing fertilizer component, helping condition the root zone so your plants can make better use of the nutrients you apply.

Where it fits

• Lawn and garden fertilizer for spring and fall feeding

• Garden plant fertilizer for vegetables, flowers, and mixed beds

• Outdoor plant fertilizer for shrubs and ornamentals

• Tree feeding under the drip line for established plantings

How to apply (follow your label)

Lawns: Broadcast 7–9 lb per 1,000 sq ft every 6–8 weeks during the growing season. Water in thoroughly.

Gardens: Apply 1–2 cups per 100 sq ft. Mix into the top 2–4 inches before planting, then side-dress mid-season if needed. Water in well.

Trees: Apply 1–2 lb per inch of trunk diameter (measure 1 foot above ground). Broadcast evenly under the drip line and keep product away from the trunk.

Shrubs: Apply 1/2 cup per foot of plant height. Sprinkle around the base (not against the stem) and water in.

Why 17-18-18?

A professional 17-18-18 fertilizer is a solid choice when you want balanced nutrition rather than a one-sided push. Used as an all purpose fertilizer, it helps you keep a simple routine across different plants, from seedling fertilizer needs at planting time to mid-season maintenance for established beds. Because this is a powder product, it’s easy to measure and portion—ideal for homeowners and serious gardeners who want accuracy without a complicated program.

Smart use tips

• Always water thoroughly after application.

• Avoid fertilizing during drought unless you can irrigate.

• Keep the product stored dry and sealed between uses.

Built for everyday gardens, this nutrient rich fertilizer can be used in beds, borders, and containers. For indoor plant fertilizer routines, apply lightly to the soil surface and water in, then adjust at the next feeding. This is a measured powder plant fertilizer (not liquid or granular), designed for consistent, labeled applications that support steady growth. Pair with watering for lawns and simple mulching in beds for better results.
