Is anyone else growing this outside in cooler areas? This plant is very susceptible to tip die back for me. In fact it has already started again. I just cut off three branches as they had the rot going. Has anyone else noticed this?
Hi Len,
I have a SP plant growing in ground since Nov of last year. It has been a slower grower but it was super tiny when planted. So far no dieback yet on it though it is a little protected by a wall behind and giant Prosperity next to it. If I get some I'll post it here.
Last winter my Rainbow Sherbet had a lot of dieback on the tips. I cut down 5 branches on one plant alone. Also Flickering Flame, Palm Springs, and even Black Dream had a few. I would seal each cut with natural tar and the good news like Chris mentioned is the new growth in spring was awesome. All that dieback on my Rainbow Sherbet has made it a monster bush now with a fantastic round shape.
Just make sure you really seal those cuts well...I had a couple that had to be cut lower as the disease kept spreading down.
