Q.sky pencil holly
My sky pencils have small (5 – 7″) growths coming directly from the ground about 6 -8″ from the main plant. Is it OK to let them continue to grow? Will they eventually become available as a new plant for me to transplant elsewhere?

You can try digging these root suckers up. Spring is the best time to propagate using suckers, as this is when plants are coming into active growth and the severed suckers will establish themselves quickly.
