Hi gardeners. About a month ago I dug two parallel trenches for my spuds and planted them up a week later, the idea bring I could earth up the spuds in the trenches. This weekend I found bees nesting in little holes in the sides of one trench (main crop) and possibly in the other (earlies). I don't want to harm the bees but I've watered the spuds and eventually I'll have to earth them up as they're starting to poke up above the soil in the trench, and that will bury the nesting holes. Help please!
