I have a small Zidi, may fruit this year. If it does, I will probably bag a couple of fruit to prevent caprification to see if they persist.
There is a large caprifig tree about 1,500 away (down/cross prevailing wind in June/July) from my original fig tree plantings which included my Marabout C. Smyrna. That apparently is too far for the wasp to fly in my conditions or they are just lazy.
There is one smaller caprifig tree about half the distance but it only had a few fruits and I found no wasps inhabiting those fruits last year. Both of these trees are on my neighbor's property which I had rented for several years but he is farming it now (farm changed hands two years ago) and he may eventually get rid of those trees but I've asked him to delay any removal and he's got more important things to do for now.
