Question: 922-1513
My turf has had large ridges for the last two years. It usually subsides in late spring. What is causing this? Billy, Smoot, WV

Mort's Answer:
Usually it is moles digging out tunnels, while they are eating grubs in the lawn. If you do not have grubs, then it is a result of frost. A low water table will make the soil lift, when it freezes. As it thaws, the soil returns to a more even level. We see this all the time on golf courses in the mountains as soils become saturated before frosts. A good grubicide will get rid of the pests eating the roots of your turf and the moles will go to someone else's turf. I suspect the culprit is Jack Frost.
