I have an old privet headge. I am fairly new property owner and I am learning. I have been working n getting everything healthy and properly maintained, but this privet has me confused. It is shaped like a hedge wall, I trim it a few times during the summer. It is not as thick as I would like it... Last year it was not really green and thick either. I figured it was from the heat. Last summer was very hot and dry. This spring they started growing and were very lots of leaves and new growth. Maybe I waited to long to prune them since I had to cut off a lot of the growth and leaves to get them into the shape I wanted. They are growing leaves again now in most spots. What happened last year is happening again. In early spring we had a heat wave of 3 or 4 days in the high 90s. It seems the leaves and growth still on the bushs went from fresh and green to leathery rough and dark with white specks that don't come off. The headges go all the way around the property, but almost all of this section turned this way overnight it seems like. Some sides of the heedge wall seem healthier then others but they all are not doing as good as they were a few weeks ago.
My care routine is I will pull out dead branches when I see them, saplings when I see them and trim them when they lose thier shape. Do I need to water these regularly like my other landscaping? I was under the impression privet can just be left alone. What should I be doing to make them healthy and full?
