About this product
Feed the soil. The soil feeds the plant.
Doonbeg is a kelp and molasses-based liquid booster that works at the soil level — supporting the conditions that keep nutrients available to your plants. Most fertilizers bypass this step entirely. Doonbeg doesn't.
North Atlantic sea kelp is a natural source of trace minerals and carbon that supports beneficial microbial activity in soil. Black Strap Molasses provides carbon compounds that support nutrient availability in the root zone. Together they create the underground conditions that make every other fertilizer you apply work harder.
Use Doonbeg alongside any GardenIQ hero fertilizer for the complete system — $10 off and free shipping when you bundle.

The science
Why Doonbeg works: Nutrx™ technology
Every GardenIQ formula is powered by Nutrx™ — a proprietary blend of carbon complexes, humic and fulvic acids, protein complexes, and amino acids developed through decades of professional agronomic research. Most fertilizers sit in the soil. Nutrx™ is designed to maximize how much your plants actually absorb — so you see more results with less product, and dramatically reduced burn risk.
