Another good reason for pruning perennial foliage occurs later in the season. During the hot months of July and August, perennial foliage often starts to look old and tattered. For many years, I sighed and assumed that yellowing leaves meant my garden was passing into its fall foliage already.

A few years ago, I started experimenting with cutting back (also known as "dead-leafing") my hardy Geraniums, lamb's ears (Stachys byzantine), lady's mantle (Alchemilla mollis) and Hosta. Even that took a bit of courage at first, but my plants looked better for it!
Then I read Tracy DiSabato-Aust's thorough treatment on herbaceous pruning in her book, The Well-Tended Perennial Garden. New challenge: the bold step of cutting some plants to the ground. This was supposed to regenerate their foliage. But would it really work?

And for those of you wondering: Just a couple of weeks later, they are sending up new foliage. We have had some rain this week, which has helped them to recover quickly. The hope is that they will have new, fresh looking foliage all the way til frost.
