What can I use to kill off St John's Wort in a couch lawn please.
Lawns • Weeds
Hello John, thanks for your question. We do not have a product registered to manage St John's Wort in lawns.
You may like to try 'Yates Zero Ultra Tough Ready To Use' as a spot spray in the lawn or paint on with the 'Yates Zero Weeding Brush'. Please use caution when using the weedkiller near other plants/lawn, because everything that it touches could potentially kill. Please ensure you have read and understood all label directions before using the product.
