cutting red tips
I have a front fence of 30-year old red tips. If I cut these back to 6 ft. tall, will they die? They are about 25 feet now. Red tips in Texas. . . hill country,
The plants should not perish, but will take time to fill in. I would suggest trimming them just as the new growth starts in the spring. By waiting, you won't have to look at stubs all winter.
