Master gardeners urge soil testing
According to the Becker County Master Gardeners, April is the time to begin to move protective cover from bulb beds, non-hardy roses and perennials in stages as mulch and soil thaw.
Don’t rush to uncover tender plants though. Mulch helps prevent the plants from coming out of dormancy too early, when damaging cold is still a possibility.
Rose canes will be OK as long as temperatures hover around 20 degrees, but most flowering perennials will die back when it’s that cold.
