I love plants! I don't have a garden but I have always had a lot of plants in my home. Will you leave your plants with the tenant when you leave?
I'll see if mine survive the winter, I'll store them here in the house in the bathroom, but there will be minimal heating on, about 5 degrees Celsius. And my mom will come here (not just to care for the plants) about once a week.

Hopefully the tenant will care for them. I hope your plants survive just fine!!
