Hi Charlie,

Your fig tree is beautiful! I don't think it will survive the winters here so I would definitely bring it inside. I would try to keep it in the sunniest window that you have and hope it does well in the winter months. You can always move it outside on warm winter days but just remember that you need to start over with hardening it off. If you are not familiar with hardening off, you just need to SLOWLY introduce the plant to outside conditions. On the first nice day (>50-60 degrees), leave it outside partially shaded for 1-2 hours. Slowly ease it into 3-4 hours a day later, then 6-8 hours, etc. And if a couple weeks pass between your hardening off days, you need to start the process all over again. I just wouldn't want to see your tree getting fried by the sun after you've worked so hard to protect it.  Good luck! 

Thank you for your response.  After posting this question, I stumbled upon a publication that suggested specifically NOT bringing the Fig tree indoors and instead allowing it to go dormant (allowing all leaves to fall off), bring it into an attached, but dark, garage (to keep it in a dormant state), then in the spring, bring it back outside again after the last frost.

Container Fig Tree Winter Storage A much easier and less labor-intensive method of fig tree care in winter is to keep the fig tree in a container and put it into dormancy in the winter. Winterizing a fig tree in a container starts with allowing the tree to lose its leaves. It will do this in the fall at the same time as other trees lose their leaves. While it is possible to bring your fig indoors to keep it alive all winter, it is not advisable to do so. The tree will want to go into dormancy and will look unhealthy all winter long.

Once all of the leaves have fallen off the fig tree, place the tree in a cool, dry place. Often, people will place the tree in an attached garage, a basement or even closets indoors. Water your dormant fig tree once a month. Figs need very little water while dormant and overwatering during dormancy can actually kill the tree. In the early spring, you will see leaves begin to develop again. When the nighttime temperature stays consistently above 35 degrees F. (1 C.), you can place the fig tree back outside. Because the fig’s leaves will start to grow indoors, placing it outdoors before freezing weather has passed will result in the new leaves getting burned by the frost.

Just to follow up on this question, I found a refernce on PSU extention to water 1ce a month. I followed that advice in 21/22 with success.  I just wanted to update anyone who may read this thread.

Water them monthly until just moist so the roots do not dry out completely. Do not overwater. Figs require a minimum of 100 hours of chilling in order to produce fruit. So you do not want to keep them toasty.Sep 29, 2021
