Q: I have a Hall's honeysuckle vine in USDA zone 8b (Tucson) which has leaf curl and some yellowing, but no aphids or other under-leaf signs of any kind. It is winter now, and the curling is progressing despite weekly deep watering (water volume at about same rate as for the past year). I thought it was the extra-cold nights (to 25F five nights in a row) last week, but the curling is progressing. Any thoughts are welcome.
At 25 degrees theleaves that have been damaged are dying. Make sure you keep it watered and play the waiting game. Hopefully it will bud out when the weather warms. Best And Happy Yardening, Nancy
