Leaves wilt frequently when there is not enough moisture in the soil and/or the temps are too high.

I'm surprised that someone shipped trees now with bare roots. If you haven't already replanted them, soak them in water (with Superthrive if you normally use it) and leave it for at least an hour and plant as normal tomorrow. Try to find a way to shade the trees after you plant them.

I've got a couple of questions too.
It sounds as if you received fig plants that either leafed out while they were being stored as bare roots, or they were bare rooted by the place of business in order to save on shipping costs. Any thoughts on this?
Either way, the leaves were looking good in the package probably because the packing retained just the right amount of moisture.
Having said that, I would pot them up, water well, and keep in the shade. It probably would not hurt to keep tham under a plastic tent until you start to see some leaf growth. Then wean from the tent and keep in the shade for a couple of months.
They should survive well. I've had this happen to me and my trees did very well.
Also wondering if your climate is hot and dry and if this is considerably different from their place of origen.

THANK YOU for your help...
I received the fig trees from Florida and I am in New York.
They were shipped bare root but the seller stated they were potted up until the day of shipment. I will be potting tonight...Can I ask what soil ammendments/mix you would recommend for the pots ? All the leaves have turned brown/black/wiltedand and are falling off, er well like leaves !
I sure hope I can save these guys...There are several fruit per tree also. Thanks.

Do not add any fertilizer or soil amendments at this time. Use a good potting soil mix like Ferti-Lome Ultimate Potting Soil. It is very good and has some dolomitic lime already added to it. Don't focus so much on the dead leaves. In fact, remove all of them so that you will eliminate any risk for fungal growth. They will eventually bud out. Keeping a plastic tent over the plants will add more humidity. Do not place in direct sunlight. Shade, shade, shade for now. Good luck!

Thank you Leon ( and James too !)
