Before i moved here i grew my (brown turkey) fig in a fig pit I dug and lined with flagstones as per the advice of that era. It worked well, lovely juicy figgies - and while my ordinary harden soil was OK in that location then a fig pit can always be filled with bagged stuff. Pit was a metre cube - probably a bit large.
The cuttings Hester sent me - 5 doing well in the greenhouse still - will probably get scattered around the curtilage in appropriate looking places - sadly no south facing suitable wall - and likely be allowed to do their own thing, bar pruning.
Fig cuttings are easy so spread the love
