Apply BARRICADE® Pre-Emergent Herbicide before weed germination for preventative control of up to 6 months. Apply in early spring (summer weeds) or late summer to early autumn for Winter Grass. BARRICADE® Pre-Emergent Herbicide does not control weeds that have already germinated; therefore, a post-emergent herbicide should be applied to remove these weeds.
NOTE - 1L bottle may be substituted for 4 x 250ml bottles pending on stock availability

First time owning lawn. Gave the team at plant doctor a ring and they supplied me with a wealth of information. Products turned up quickly.
Will definitely be getting more 8 weeks difference been using stimulizer, activ8mate, soil wetter, seaweed secrets and champion fertiliser. Was super fast delivery.
Only have great things to say about Plant Doctor. Organic products and a competitive price, fast shipping and easy to contact with questions. Have had great results with the special mix for lawns, and my plants (indoor and outdoor) love the seaweed secrets. I am excited to test out some of the animal products soon!
