Product Details
RootLock 4-0-12.5 + Seaweed Extract – Soluble Turf Biostimulant
Unlock your lawn’s hidden strength.
RootLock is a high-performance, 100% soluble seaweed concentrate designed to drive deeper roots, richer colour, and long-term turf health. With over 60% active seaweed extract from premium Ascophyllum nodosum, it delivers a powerful combination of natural biostimulants, nitrogen, and potassium to help lawns recover, repair, and thrive.
By improving root length, density, and microbial activity, RootLock enhances nutrient uptake and soil structure — keeping lawns greener for longer, even under heat or traffic stress.
How much to apply:
Apply 1 L per 1,000 m² diluted 1:10 in water (≈ 10 L spray mix per 100 m²).
Use with 4–10 L water/100m2 and apply evenly to actively growing turf using a calibrated sprayer.
Compatible with most fertilisers and biostimulants. Avoid spraying near concrete or porous pavers due to iron-related staining.
Ideal for use during renovation, recovery, or high-stress periods, RootLock provides fast visual response with deep, lasting results.
If you’re unsure when or how to apply, explore The Lawn IQ Programs, we’ll tailor a plan that syncs RootLock perfectly with your soil health, season, and growth cycle.
