Anti-worm killing treatments for lawns

Asked September 9, 2016, 2:47 PM EDT

I treated my lawn with a lawn feeder and regrettably managed to kill many worms. Is there a product which will feed grass but not kill the worms please?

Fertilizer products that do not contain herbicides or pesticides should be fine for your worms (ammonium nitrate, ammonium sulfate, urea). You might also consider compost or other organic fertilizers. These generally contain lower nutrient percentages, but will still get the job done if applied appropriately.

Best regards.

Hello Kelly, thank you so much for your reply, very helpful. I am sad that manufacturers are allowed to sell these products as I had no idea it was so lethal to worms and it gave no warning on the packaging.

kind regards

You're most welcome, Anne.

Best of luck to you and your worms. :)
