One of the hardest things for gardeners in Maine is waiting to plant until the soil finally warms up sufficiently. A good way to pass the time is to read and plot and plan about your future garden and nowadays it’s also possible to watch videos: a grand distraction for old timers and welcome instruction for novices.
BBC has over 100 free little movies about hands-on gardening, which are excellent mini lessons.

Take care, however, to adjust for the differences in planting times!
