Gardening at a summer fishing cabin
I live in Oklahoma, USA, but my family owns a fishing cabin in Ontario on Marchington Lake, northeast of Sioux Lookout. I would like to add some plantings to the property but since it's only occupied a week or two at a time throughout the summer, I can't plant things that need a lot of care. I am very unfamiliar with cold climate gardening (I live in zone 7) so I'd appreciate some advice on what to plant, or if I should try to garden there at all. Thanks.
