I have some mini roses that were about 6 inches high and this year they have suddenly shot up to about 2 to 3 feet high with red roses that turn brown shortly after opening up. Is this what happens to mini roses? I'm tempted to dig them up or should I trim them back and wait to see what happens? They are at the front of the flower bed and are now in front of shorter plants. I'm in zone 5.
