It has a very early fruit set and an excellent productivity. Compatible with all varieties, it adapts to various soils, in particular heavy and asphyxiating ones.
Nevertheless, the Gisela 6 has a certain sensitivity to high summer temperatures. In soils that are not very fertile and with very productive varieties, it is possible to see a deterioration in the vegetative state of the tree.
Moderately sensitive to collar rot, it is also tolerant to viruses and displays a good resistance to crown gall.

It requires regular pruning, which is necessary to manage the heavy load and maintain fruit caliber.
