Desert King and Hardy Chicago.

i would cut the all top open and then cover with upside down garbage can or something similar (even more plastic) very loose on top and sides , in order to stop rain and create air flow, any moisture from the inside would go to top and then come down on outside of sides. I'm sure someone else  might have a better idea, but you definitely need to get moisture out. 

thanks guys... I'll make some alterations once this crazy weather passes.

Hi Tyler
I've been trying to find the video of a older Italian gentlemen,
in Pa winterizing is 10 foot high fig tree and the idea is roughly the same as yours except
he did put a pvc pipe in the middle and coming out near the bottom for airflow.
maybe somebody else saw it and will be able to post a link

Tyler
I think you did a great job! 
I love the idea of the bricks at the bottom.  Should deter mice.  a 1/4" metal cloth around bottom might also help.
Also a white covering (versus black) should go a long way to manage heating issues.

It will be interesting to see if your desert king will produce any brebas growing in the great z6 outdoors?

Hi,
Here laying plastic on dirt (keeps the dirt dry) and bricks on dirt is called a mice hotel (moles and voles).
I would really be worried about that. They would build their tunnels around the roots and that is the end of the tree.
That is the reason why I use dirt from the nurseries to fill the area and nothing making a cut in between the local dirt and the dirt for the protection.
In your locales, it could work without problems. You may have less moles and voles.
Only time will tell ! Good luck !

I have two in ground smith decided to wrap one may wrap the other they about 4-5 feet tall. I have one in 10gal pot. Do you find the TXBA 1 taste similiar to the smith? I haven't tasted txba 1 yet, I do have a small one, the leaf are similiar to smith that is if I have the correct TXBA 1. I usd to think that the non cold hard fig such as smith and others, after they are protected a few years until they are larger. The somewhat mild winters like mine and yours they would get large enough to be able to take a bit more cold and not die completely back to the ground. 

Thanks
