I’d like to train a Golden Opportunity on a 4 foot wall so I can espalier the canes for a wide spread against the wall. This rose is described as having vigorous growth to 10 ft+ tall.
Question: If I let the canes grow to about 6 ft vertically and tie them horizontally, will the canes stop growing in length? Can I “fool” into more length?
If you can, shape the canes like a fan, you will get the most blooms from the laterals that will grow from the arched canes.
