The Smart-Dyson System
This
system uses cordon training, with two cordons either side of the trunk.
Each cordon bears a number of spurs, which produce the fruiting canes.
As always, the cordons are permanent, and the system is subject to spur
pruning. This method is also very suitable for mechanical harvesting,
but it also has the advantage
of being suitable for mechanical pruning, and consequently has gained
favour in the New World. It is named after the developers, Richard Smart
and John Dyson.
