I have a question and I want to know the oppinion of people who have experience with this or others who can give me some light.
I have a very nice UNK Turkey fig that produces amazing quality fig. Unfortunately the tree has FMV and it's not growing well. Right now it's in a 5 gallon pot. It produces very few figs, but they are high quality.
Right now the tree has tree thick branches that I could airlayer them.
My question is: The airlayers of that tree will still have the FMV? I supposed the answer is yes. If that the case, an airlayer in more easy to cure the FMV than the original tree?

One last question, since this tree has FMV, it will be wise to airlayer all the 3 branches at the same time or is better to do it one at a time? I don't know if the tree has enough energy to produce 3 airlayers at the same time.

Graft it onto healthy rootstock. Helps a lot.

Air layers do not cure FMV, but under ideal conditions i.e. Soil, temp etc... the tree will produce and shake the FMV symptoms off. It takes a longer time for such tree to grow and it's always an uphill battle depending on the intensity of the symptoms.
When you do air layers do not injur the branches, just wrap them up and remove when you see enough roots, leaving enough leaves on the mother tree. I would not use all three branches.

Thanks both of you!!! I will Air layer one branch and then grafting that to a healthy and vigorous rootstock.
Then I will see if I can "Cure" the mother plant.

If Harvey wasn't so busy he'd chime in. He has had a lot of success grafting infected FMV varieties to healthy root stock. The results have been amazing. There may be some posts about it use the search function.

According to Bill's potted figs article they will produce less and less and eventually die if you don't root prune. If your tree has been in that container for more than 3 years, it may be worth taking a look at the root ball and see if you can help it by pruning or moving it to a larger pot. http://figs4fun.com/bills_figs.html

Mahdi, you might also want to look up information on heat therapy.  Many plants can be freed of viruses by maintaining them for extended periods at high temperatures that don't kill the plant, but inactivate the virus.  I've read that this works for figs.  I can't recall the time and temperature required for figs.  Perhaps root up a bunch of plants and try this with them in pots (so the roots are heated as well).  If anything survives you might then have clean stock to grow going forward.
