Root-forming sticks (2) are placed parallel in the ground (5) and grafted or connected vegetatively. The fruit forming scion wood (1,3,4) are set ascending and grafted together (3,4) and/or only with rooted wild wood and root-forming sticks so that the scion wood can form roots when dammed up with earth. The fruit-forming scion wood can be connected together above the ground like a roof. The root forming wild wood can be arranged above ground and/or below ground. ADVANTAGE- Faster growing times for the roots and thus earlier crop results.
