cutting these back at the appropriate time is a familiar and easily understood task.<\/p>\n<p>There are many other pruning techniques that gardeners can make use of at other times of the season, in an effort to coax the best possible performance and garden worthiness from their perennials.\u00a0 These are less familiar tasks to most gardeners, but worth exploring at this point in the season when a quick and timely trim can produce some amazing results.\u00a0 I&#8217;ve broken the techniques into a few basic groups.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-3596 aligncenter\" src=\"https:\/\/www.perennials.com\/content\/wp-content\/uploads\/2017\/01\/CentaureaAmethystInSnow-502.gif\" alt=\"\" width=\"695\" height=\"695\" \/><\/p>\n<p>&nbsp;<\/p>\n<p><strong>Deadheading<\/strong><\/p>\n<p>This idea is a simple one and fairly familiar: by trimming off the faded flowers, many perennials can be coaxed into producing more buds and flowers, rather than wasting their energy forming seeds.\u00a0 For certain plants (peonies, for instance), although no amount of deadheading will trick them into repeat bloom, plants look so much better after deadheading that it becomes part of the regular list of summer chores.<\/p>\n<p>New gardeners often ask us how far down to cut below the flowers, but unfortunately it&#8217;s not always an easy thing to explain, each type of plant responding in a slightly different way.\u00a0 Experimentation is the best way to learn this; after playing around with it for awhile, most gardeners sort of develop an instinct about where exactly the cut should be made.\u00a0 A few general tips:<\/p>\n<ul>\n<li>Don&#8217;t cut off any developing flower buds.\u00a0 This sounds obvious, but sometimes the buds are not always large and easy to find &#8212; they may be hiding among leaves or very tiny.\u00a0\u00a0 Follow the stem down below the faded blooms to see if any new flower buds are present.\u00a0 Cut off the faded flowers along with the stem to just above these new buds.\u00a0 With plants like Coreopsis &#8216;Moonbeam&#8217;, the buds are usually held just below the faded blooms, and a pair of hedge shears comes in handy for this task: just lightly shear the very outside of the mound, taking off the finished blooms and leaving the buds to come on later.\u00a0 If no buds are present, then a slightly lower shearing will encourage new ones to form in due time.\u00a0 Deadheading the individual blooms of a small-flowered plant like &#8216;Moonbeam&#8217; with hand pruners would be tedious, to say the least.<\/li>\n<\/ul>\n<ul>\n<li>Perennials with heads of flowers, or with daisy-shaped flowers usually look better if at least some of the stem below the bloom is cut off, along with the faded flowers.\u00a0 This helps to avoid that unpopular &#8220;decapitated&#8221; look.\u00a0 Cut these back to a thicker main stem, where new buds are probably already forming.\u00a0 Perennials that respond well to this include Purple Coneflower (Echinacea), Shasta Daisies (Leucanthemum), Rudbeckia, Yarrow (Achillea), Blanket Flower (Gaillardia) and Beebalm (Monarda).<\/li>\n<\/ul>\n<ul>\n<li>Deadhead individual flowers, when new buds are forming on the same stem: this is necessary for Daylilies (Hemerocallis), Peach-leaved Bellflower (Campanula persicifolia), Balloon Flower (Platycodon) and a few others.<\/li>\n<\/ul>\n<ul>\n<li>Deadhead any plant that self-seeds around, if you wish to prevent this from happening.\u00a0 Good candidates include: Columbine (Aquilegia), Sweet William (Dianthus barbatus), Common Yarrow (Achillea millefolium), Perennial Bachelor&#8217;s Buttons (Centaurea), Jacob&#8217;s Ladder (Polemonium).<\/li>\n<\/ul>\n<p><strong>Light Shearing Back<\/strong><\/p>\n<p>With many of the spring and early-summer flowering rock garden perennials, a light shearing after they finish flowering will keep them in top form for many years.\u00a0 This helps to maintain a dense and bushy habit, keeps them from dying out in the middle too quickly, and also prevents them from self seeding.\u00a0 Shear these types of plants back by half after flowering: Wall Cress (Arabis) Rock Cress (Aubrieta), Perennial Alyssum (Alyssum and Aurinia), Evergreen Candytuft (Iberis), and Moss Phlox (Phlox subulata).<\/p>\n<p><strong>Cutting Back Hard<\/strong><\/p>\n<p>With just a few exceptions, the vast majority of late spring and early summer-blooming perennials take a fast nosedive after flowering, and can look fairly hideous later in the summer.\u00a0 The mounding types of Cranesbill Geraniums and Silver Mound Artemisia are just two examples of plants that are notorious for looking terrible by July.\u00a0 With both of these a hard shearing back will encourage a new round of fresh, healthy and compact foliage to be produced, causing the plants to actually be an attractive addition to the border during the heat of summer.\u00a0 Cut Cranesbill Geraniums back more or less to just above the ground after blooming, taking care to leave the already-forming new foliage in the centre of the clump untouched.\u00a0 With Silver Mound, I like to shear the whole works back to 2 inches in height as soon as the tiny round silver ball-shaped flowers appear in mid to late June.\u00a0 This hard-pruning technique also works well with any of these: Lady&#8217;s Mantle (Alchemilla), Old-fashioned Bleedingheart (Dicentra spectabilis), Chrome Spurge (Euphorbia polychroma), Catmint (Nepeta), Blue Salvia, Meadow-rue (Thalictrum), Spiderwort (Tradescantia).<\/p>\n<p><strong>Pinching for Height Control<\/strong><\/p>\n<p>Pinching of fall-blooming Garden Mums (Chrysanthemum) is a familiar technique for most perennial gardeners.\u00a0 The same basic concept works for these late summer and fall bloomers: Monkshood (Aconitum), Michaelmas Daisies (Aster), Joe-pye Weed (Eupatorium), Helen&#8217;s Flower (Helenium), Beebalm (Monarda), Summer Phlox (Phlox paniculata), Autumn Stonecrop (Sedum) and many, many others.<\/p>\n<p>June is the ideal time for cutting these back.\u00a0 Pruning off one half to two thirds of the growth will result in an especially bushy plant, with reduced height and often considerably more flowers, although smaller in size.\u00a0 This technique is especially useful to reduce the need for tedious staking.\u00a0 Pinching too late in the season can cause some of the autumn bloomers to flower so late that the frost gets the blooms before they have a chance to open.\u00a0 In general, pinching fall bloomers no later than the beginning to middle of July is wise, across Canada and in the northern States.<\/p>\n<p><strong>The Ultimate Pruning Reference<\/strong><\/p>\n<p>An indispensable reference book for the addicted perennial gardener is The Well-Tended Perennial Garden by Tracy DiSabato-Aust (1998, Timber Press ISBN 0-88192-414-8).\u00a0 Tracy&#8217;s colleagues refer to her as &#8220;the deadhead Queen&#8221;, and she offers an extremely thorough look at every aspect of perennial garden maintenance.\u00a0 Chapters on site and soil preparation, pests and diseases, plant selection, pruning methods, staking and everything else a gardener needs to do are both detailed and entertaining to read.\u00a0 Especially useful is the A to Z encyclopedia of perennials, with all the maintenance requirements for each plant laid out in a quick and concise format.<\/p>\n<p>&#8212;
