There are those who have tried out the Labruscan varieties from Ontario. These cannot be grown under Guyot pruning methods but must be cultivated by a simpler system such as one main rod plus six strong side growths, which are pruned back hard each January.

They could also be grown on the ‘Grow as you like’ system, being allowed to scramble over a trellis or cover a fence or wall. Under this system very little pruning is necessary, though it does pay to cut back the fruiting laterals in the summer at two leaves above a bunch.

The leaves of the vines grown against walls are often attacked by Red Spiders, and the answer here is to syringe the under surface of the foliage in the evening, twice a week, from the beginning of June onwards. In cases of bad attack some liquid derris should be added to the water.

Once in position the rod is cut back, by about a quarter, and then the shoot which develops from the end bud is tied along the bottom wire until it reaches the next cordon where it is pruned, in the summer, to just above a bud. The laterals or side growths that develop from the lower parts of the cane are tied to the top wire when they are long enough and they are then pruned.

Some people give each vine one stake, 4 feet out of the ground, and then, instead of tying the rods out to ‘form a goblet, they merely tie the tips of the rods to the top of the stakes to form an inverted cone. By the way, do not allow the young cane to go on growing after the requisite number of bunches of grapes have been produced. You should always pinch out the growing point at 3 leaves beyond the top hunch.

This method is not suitable for varieties producing very thin canes or for those which bear the best fruit at the end of very long canes.
