Common winter injury symptoms

Purdue Extension - In The Grow

Q. I have a yucca tree that is 5-6 years old. What was a small plant has become a mature tree. I transplanted my yucca to a larger pot last summer. There was a significant explosion in growth. If you look at the picture you can see the growth.

Unfortunately, it suffered through this past winter indoors. Much of the new growth witnessed last year is gone. Please see the attached photo — I think it speaks for itself. The green foliage died over the cold winter, yet you can see the growth shoots that remain.

Do you have a suggestion for helping this tree? — R.M., Tippecanoe County

A.It’s not too surprising that there was more dieback that usual this year given the extreme cold conditions we experienced this winter. Even indoors in unheated garages got colder than we typically expect. The new green growth at the lower part of the plant looks great. Just cut off the brown, dead stems and the plant will immediately look a lot better! Be sure you cut back to just above where there are healthy looking new shoots.

Q. I planted a Weigela ‘Wine and Roses’ shrub about five years ago and it has done well in previous years. But this spring, there seems to be a lot of dead branches and only sparse flowers. Is there something I can do to help this plant? — N.L., Zionsville, Indiana
