junis are able to withstand -20F they are very hardy. put it on or even bury the pot in the ground in a palce protected from wind and let it get burried in snow. the green will change to a blue and even purpleish color this is fine.the tree will be back in spring. if it is in an unheated garage it will need some light and put snow over the pot ...junis will not survive indoors without very special care. best of luck

if you want a bonsai to keep inside look into tropical bonsai theyr great

hello again. so i did everything you told me. but the new shoots that he had look dead. do i just wait till spring?

your plant looks ok, winter tends to discolour the foliage. Wait until spring and you will find it will come back. Leave the snow it is insulating the plant.

My little Bonsai is not showing any sign of life. During winter he stayed outside in non windy sunny place buried in earth. This is how he looks today. Brought him in to take a good look at him!

It does not look too bad, You need to start watering and adding fertiliser, then it needs some pruning too. It is very difficult to tell from the pictures what to prune but it does look very bushy. Kepp it ouside in the sun and it will soon green uo,
