| Re: Mystery of the sycamore There were a group of Nobel and Grand Firs on the first estate I worked on that had been part ring barked to improve seed production. Apparently, this puts the tree under stress resulting in a heavy seed crop in order to survive.
The two semi circular rings almost met, there were two very slim diametrically opposed viable strips of cambium on these 150' trees which survived the experience. The seeds were collected and used in the commercial nursery. |
