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?
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).
