|I have 15 pink bower vines along my back iron fence and the leaves have turned brown. They are 3 years old and this is the first time this has happened. It has been a bitter cold winter here in southern
CA and I was wondering if they froze. Please advise me if I should cut them back or dig them up. I appreciate any expert advice you can provide. Thank you.
|The cold weather has taken a toll on many, many plants in your gardening region this winter. Pink bower vines are hardy only to about 30F so it's likely the vines have been killed back to the ground. I'd prune them back in anticipation of new growth this spring. As long as the roots survived the cold spell, they will develop healthy new stems when the weather warms. Pink bower vines are routinely cut down to ground level every 3-4 years to help control their size so cutting yours back won't hurt it a bit.
Best wishes with your landscape!
