Production of French Bonsai
Cold Greenhouse Bonsai
From spring to autumn, they can stay outside without any problem (and they will be all the better for it). But they are afraid of frost, so in winter they will need to be protected. Avoid putting them in your home but instead find a place that is bright and not too heated. As long as the temperatures are not below zero, they will be happy and start a new growth cycle the following spring.
