Will miniature citrus trees grow well indoors in western Wisconsin?

I take my citrus plants inside during the winter in North Texas. They are very tolerant of indoor living as long as they get some sunlight. Even your large E. windows should work. They drop sticky dew during the winter so you may want to put plastic under their wing span. You should take them outside when the temps stay over 45 degrees day and night. They love being outside in the sun for the summer. Then back inside when it goes below 45.

If you have a large enough greenhouse or sun room - yes. They go a little dormant during the shorter days but live very well if given enough sunlight or artificial light and are kept warm enough (above 70F would be ideal) In your setting, it would work if the window faces south but do not place the plants to close to the window so they get cold when it drops below 32F.

Not likely, even with grow lights
