I'm trying to grow my persimmon tree, but my country has a very cold weather in winter and a few months with above freezing daytime temperature in summer (USDA hardiness zone from 2 to 4), so I am growing this seedling indoors. What can I do to keep it alive?

4Need some more information. Where exactly are you and what kind of persimmons do you have? Some persimmons can withstand decently cold winters into USDA zone 4– EscoceJan 22, 2016 at 18:24

Is a heat mat a consideration? 14° F. is pretty cold for indoors. Is it that cold where you are, or just where the tree is? What are your hopes for the tree?– BrōtsyorfuzthrāxJan 18, 2018 at 1:00

After a week it is growing well at -10°C (14°F). I don't know its soil temperature, but I am using the following method to keep it warm:
- During night I am covering it with plastic bag and blanket.
- During daytime I am trying to let it get more sunlight by using metallic kitchen paper.
Editor's note: I believe the temperature indoor might be indeed -10°C (14°F) because outside it's usually -30 to -40°C (-22 to -40°F).
