HOW TO CONTROL PERIWINKLE

Apply WEED WEAPON ready to use, or WEED WEAPON concentrate with STICK SPRAY, all year round. Follow up on re-sprouting areas twice a year.

Cut down periwinkle and immediately apply INVADE GEL to all cut ends to kill root systems effectively.

Small patches can be dug out but ensure all roots are removed as these will re-sprout. Dispose of plant material at a refuse transfer station or burn. Check for regrowth.
