Rafed, thats almost scary. I am not sure my tree is large enough for anything like that. but i havent really firtalized it other than compost and such. i plan on feeding all the figs real good once the ground starts the thaw in spring right brfore the buds swell. maybe they will spring up large like i have read they have done for some.
All the info i have gotten about VdB is that in my area zone 6b (very close to the 7 line) that the tree will require winter protection for three years and should do well without it after that time. our winters here the past few years have been warmer than normal to say the least. i also have unprotected, blue celest, brown turkey, purple magnolia, my hardy chicago, and desert king. as i said all unprotected in the snow right now and still looking good. i have alot more that will be added in spring time. some will need some protection for a couple years i am told but after all should do fine. these are but not limited to MvsB, Osborne prolific, Sal's C, Sal's G, O'Rourke, black Bethlehem, VdB, RdB, Lattarola, Lsu Hollier, about 5 dif unknowns from the northeast. and many more. some i will have to grow potted Aboque Pitite and a few others. but hopfully this project will work out well but only time will tell.
