How they work together

LIQUID GROW & BLOW does two jobs in one tank.

THE WEED-KILLER
NSFW

A three-way mix of actives that hits broadleaf weeds through multiple pathways — right down to the root.

THE FEED
THREEWAY

A 15-4-8 liquid fertiliser with trace elements, greening the lawn through the leaf for up to 8 weeks.

SPRAYED TOGETHER, IN ONE PASS

NSFW clears the weeds while THREEWAY feeds the lawn into the gaps they leave — the lawn thickens up as the weeds disappear.

How much should I apply?

Not happy with kill

Sprayed my lawn 6 days ago. Following instructions on pack for broad leaf weeds and to date am not completely happy with the results

Killer stuff

Results after 1 application. Those broadleaf nasties shrivelled up giving the lawn a chance to thrive!! Easy ordering and prompt delivery was a bonus!!

Liquid Grow & Blow Pack

Yep guilty of use the cheap crap and getting no where. Mix the two and sprayed, you could see within a couple of days the weeds pointing their toes up. Going to have to sharpen the bloody mower blade now to cut the healthy grass.😂😂
