When is the best time to trim upright yews. I have approx. 26 plants along 100' edge of my property line. They are approximately 25 years old standing 10' + I want to trim them back to six feet. Any suggestions how and what time of year. Thanks

Yews are very tolerant of pruning. A general rule of thumb on pruning is to take no more than 1/3 of the foliage back at a time. Old yews can be rejuvenated by cutting into wood with foliage but it will take several years for the plant to regrow and assume an acceptable appearance. If you are going to cut back that far, it is too late in the season and you will have more success by waiting until spring. LW
