How do I rid my lawn of worm casts?

💡 Our Advice
You can't kill them but you can encourage them to move away. Worms prefer a soil pH above 6.5-7.0, by lowering it you can discourage them. Treating the lawn with Castclear or Sulphurlawn Chips acidifies the soil. These products don't harm the worms they just move out of the lawn. You may need to spike your lawn more often.
