Invest in your soil!
Improving soil quality is critical to successful gardening. It's that simple. Plants depend on great soil, and without it, they won't thrive. That's why we created Dirtilizer. The first dual-action biobased fertilizer and soil conditioner that feeds plants and conditions your soil using a unique blend of biobased ingredients. Dirtilizer's 3-0-3 NPK analysis reduces the dangers of overfertilization (when applied according to label directions), including fertilizer burn, salt accumulation in soils, and excess runoff into watersheds that traditional high-concentration synthetic fertilizers can cause. When combined with regular additions of organic matter like compost, and mulches, Dirtilizer is the perfect supplement and complement to an overall soil quality program.

Improve Soil, Feed Plants, Grow More!
Dirtilizer contains liquid kelp extract, nitrogen (N), potassium (K), micronutrients (iron), and humic acid, which work together to act as a soil improver and to enhance plant growth and vigor. We specifically left out phosphorous (P) because most home lawn and garden soils often don't need phosphorous (unless a soil test says otherwise), and overapplication can harm beneficial soil organisms and lead to excess runoff into watersheds.

Easy to use and apply: Dirtilizer is easy to apply using a watering can, hose-end sprayer or, garden pump sprayer. Dilute 2 ounces of Dirtilizer with 1 gallon of water and apply every 2-4 weeks during the growing season for incredible results.

A little goes a long way: Dirtilizer's concentrated liquid fertilizer and soil enhancing formula makes up to 16 gallons of ready-to-use product that will cover up to 16,000 square feet.
