How do you prune a rambler?
There are two main types of ramblers. The first types called Wichuraianas ramblers, have long pliable canes that
produce one long display and then start growing lots of new canes from the base. To make room for the new canes
you cut out the ones that have flowered right after the blooms are finished. If there aren't many new canes you can
leave a few of the old ones but prune back their laterals to three inches. The second type called Wichuraianas climbers have stiffer growth and make new canes from part way up the old wood. The new growth is retained and any of the very old wood can be pruned out.
