Pittosporum Froze In Texas, Will It Survive?

Question

We had 200 hours of below freezing temps, including one night if a negative one degree. My dozens of mature pittosporum bushes have leaves that have turned brown and are falling off. Will they survive?

Answer 1

They can survive freezing temperatures, and in fact, will grow down to zone 8. However, that extreme cold night may have caused some damage.

At this point, I wouldn't do a whole lot to them. Once you start to see some new growth, you can figure out what is in need of removal. Anything that refuses to put out new growth will need to be pruned.

Sometimes, B Vitamins that are meant for plants can help them to recover from shock, but this is not guaranteed.

While you wait for recovery, these articles will give you a chance to catch up on some reading about the shrub:
