Yesterday I took the hose and just let it run...half hour later saw a tunnel out, no more today. Veggies are in mounded rows there so they can tak a good drink. Lil worried about a row of Toms that are fruiting getting too much water from that but its so hot here they dry up pretty fast.
Plant daffodil bulbs on the edges of your garden. They are poisonous and moles wont burrow past them. Also are you having dry weather? I had problems with moles eating my garden a few years ago and during a very dry summer. I discovered if I poured water in their tunnels in the lawn that they quit coming down to the garden to drink and staying for lunch.
