No. BioPrime™ is a low‑salt, low‑burn soil conditioner made from gypsum, humic acids, seaweed and volcanic rock dust. It’s safe for common Aussie grasses (Buffalo, Kikuyu, Couch, Zoysia) when used as directed. Stick to the label rate and water in after application.

BioPrime™ doesn’t poison weeds. It fixes the root cause—weak soil—so grass thickens and crowds weeds out. Expect a steady reduction over 4–6 weeks with regular mowing. For quick knock‑down of existing weeds, you can spot‑treat with a lawn‑safe selective herbicide or hand‑pull, then keep BioPrime™ as your ongoing defence.

Yes—once watered in. Ingredients are non‑toxic and commonly used in soil improvement. Keep the product out of reach before use, apply on a calm day, and water in. Pets and kids can go back on the lawn after it’s dry.

• Week 1: Roots and microbes wake up.
• Week 2–3: Noticeable green‑up and thicker cover.
• Week 4–6: Weeds lose space as turf fills in.

Cooler temps or heavy shade can slow things a bit. Want faster colour? Pair with ReGreen™ foliar iron for a same‑week boost.
