Heucheras, often known as coral bells, are gorgeous, shade-loving foliage plants that come in a wide variety of brilliant colors. Despite being lovely, these endearing evergreen perennials frequently deteriorate after a harsh winter. But there is a straightforward fix—just prune them!
By eliminating the ragged old growth or the old, unattractive leaves, you can clean up your heuchera while making way for new growth. Here are four useful suggestions for pruning heucheras:
- The right time: Early spring, before the onset of new growth, is the ideal time to prune heucheras. Look at your plant: Make sure to pay attention to the boundary between the old and new growth. The core of the plant will have new growth, and the margins will have old growth. Trimming this young leaves could injure or impede the growth of your plant, so exercise caution. Trim old growth by cutting it off close to the root and gently pulling it away from the plant. Keep an eye out for damaged or sick growth and take care to remove it. You want to move around the plant, removing nothing but fresh, healthy growth. Compost: You can add these clippings to your compost pile if you have one so that they can be used in the future on your garden. Please take note: do not throw any suspected unhealthy clippings to the compost pile!
You can maintain the health and radiance of your heucheras with the appropriate amount of love and care!

Before spring, when should I trim my trees?
After flowering is the ideal time to prune. It is possible to renovate or drastically diminish a plant in the late winter or early spring, just before growth gets underway. Cut back to healthy outward-facing buds after removing the spent blooms (deadhead). Eliminate straggly growth and old, sick, damaged timber.
Deadhead your Heuchera plants?
DEATH HEAD FLORALS The majority of heucheras bloom, usually starting in late spring or early summer. Snip the flower stems slightly below the foliage level when the petals fade to help extend the flowering time.
Are coral bells pruned back for the winter?
In the fall, trim off any spent or damaged growth from your Coral Bells. Throughout the winter, keep the remaining vegetation in place. Zones 6, 7, and 8 allow the plant to become an evergreen and keep its foliage all winter. In colder climates, the foliage will aid in shielding the plant from chilly air and snowfall. After there is no longer a threat of frost in the spring, foliage that died back during the winter can be removed.
How soon should I prune my coral bells?
Coral bells don’t require much upkeep, but you can prune off the entire flower stem after it blooms to direct the plant’s energy into developing additional leaves. After winter, if the leaves start to appear a little ragged, trim them back and new growth should rapidly take over.
Heuchera dieback over the winter?
According to the University of Illinois Extension, coral bells (Heuchera spp.), which are native to North America, are ideal plants for the shady section of the garden in U.S. Department of Agriculture plant hardiness zones 3 through 8, depending on the species. Coral bells, sometimes known as alum roots, can grow as evergreens but may die back in your climate, especially during colder than usual winters. Give your coral bells a little careful loving care during the winter to ensure that their unique foliage and blossoms reappear the following year.
Phlox
Phlox may bloom from late spring through the end of summer, but once cooler weather sets in, they begin to fade. We advise reducing their height in the late fall mostly because to powdery mildew. Powdery mildew can develop on Phlox, especially if the leaves is damp for an extended period of time. Even mildew-resistant cultivars, such as those released by Proven Winners, are more susceptible to infection in the cool, damp fall months.
*Before pruning other plants, destroy any foliage that exhibits powdery mildew symptoms and clean your pruners.
Bee Balm (Monarda)
Bee balm, also known as Monarda, is prone to powdery mildew, much like phlox, particularly in the moist fall months. We advise trimming the plants back in the fall and clearing away any waste, no matter what kind, to avoid the disease coming back the next year! Your plants will have a fresh start the following season.
Yarrow (Achillea)
It’s okay if certain perennials don’t have a stunning winter appearance. When winter comes, yarrow (or Achillea) has pretty… ugly spent foliage. In the fall when the foliage is at its peak, we advise only a partial pruning. Yarrow produces new basal leaves late in the growing season. To safeguard the crown over the winter, remove any outdated foliage while keeping the fresh basal leaves.
*Pro tip: Cut the fresh flowers to enjoy inside, or keep the fallen flower stalks for winter appeal.
Spike Speedwell (Veronica)
Spike speedwell, sometimes known as Veronica, has a whimsical appearance from spring through fall, but once the first frost arrives, they soon lose that appearance. Similar to yarrow, we advise pruning them back to the basal foliage because it also develops late in the season close to the crown. When winter is through, it will freshen them up and get them ready to resurrect.
Astilbe
The fern-like, lacy foliage of the astilbe remains healthy and green from spring through fall, but with the first frost, it soon turns yellow and brown. The spent blooms retain their fanciful texture, whilst the foliage becomes somewhat lifeless. For garden organization, we advise trimming down the leaves, but retaining the dead flowers for winter appeal.
*Do you dislike the way dead flowers appear in the garden? Consider trimming them to use in indoor dried arrangements.
Columbine (Aquilegia)
Old-fashioned gardeners love columbine (also known as aquilegia) for its brilliant bloom display in the spring. What’s the best method to get it ready for spring success? In the late fall, remove any outdated foliage or blossom stems. Additionally, it will take out any barriers for springtime growth, preventing illness and pests from returning!
Daylilies (Hemerocallis)
In bright, grass-like bunches that droop and turn brown in the winter, daylilies (Hemerocallis) thrive. Is a fall cutback important for the health of the plant? No, however some gardeners favor a more tidy appearance in the winter. By pruning them after they become dormant, you can avoid the problem in the spring!
Hosta
There is one solid reason to prune hostas back in the fall, even if leaving the foliage standing during the winter would preserve the crown. Slugs! Taking off the leaves after a frost will prevent slugs from returning in the spring since slugs lay their eggs in dead hosta leaf. We advise trimming them in the late fall, particularly if your garden is overrun with slugs.
Still uncertain? Remove all of the detritus after cutting it down partially, leaving 4-6 inches standing above ground.
Catmint (Nepeta)
The aromatic foliage of catmint (Nepeta), which is fresh from spring through fall, soon turns yellow and brown when it begins to frost. This is considered an eyesore by some gardeners, who prefer to cut it down for a neater appearance. We strongly advocate leaving at least 4-6 inches of the plant’s crown above ground if you do decide to chop it back in order to preserve the crown from the elements.
Salvia
Salvia is a garden favorite in the summer but leaves a bit to be desired in the winter. Like their foliage, flower stems generally flop over and turn brown. While others choose to cut it back for a neater appearance, some gardeners decide to let it standing till spring. You are in charge! Trim it down to the fresh basal growth, which shields the crown from the winter elements.
What should you avoid pruning in the springtime?
Pruning tasks should begin with evergreens with needles, such as pine, juniper, or yew. Pruning broadleaf evergreens planted for their foliage, such as boxwood, privet, hollies, and euonymus, is also recommended. Focus on correcting plant shape, eliminating errant branches, or pruning undesired branches for these plants. Old wood shouldn’t be chopped into since it might not regrow.
Prune shrubs including the rose of Sharon, crape myrtle, hardy hibiscus, butterfly bush, and Peegee hydrangea that don’t bloom in the spring. To shape plants and thin the interiors of shrubs, place pruning cuts. The optimal time to prune summer bloomers in the coldest regions is after all threat of frost has passed.
Prune summer bloomers in two phases if they need to be nearly cut to the ground. Trim the height first, but wait until there is no chance of frost to trim the stems to their final size. Lilac, forsythia, weigela, and fake orange shrubs that bloom in the spring shouldn’t be pruned until the flowers have faded.
If you prune a few stems from red- and yellow-twig dogwoods each year, cutting them to the ground, you can maintain the plants’ vibrant appearance. Keep these bushes in good condition so that their stems never get older than three years.
While plants are still dormant or as new growth appears in the coldest zones, deal with pruning shrub roses. Make cuts to shape plants and clip stems that have been harmed by the cold. Only prune winter-damaged vegetation off climbing roses in late winter or early spring.
While still dormant, shape summer flowering vines. Along with clematis that bloom on new growth, this group also contains trumpet vine, passionflower, honeysuckle, bittersweet, and passionflower.
Just before they begin to leaf out, prune deciduous trees. Pruning early spring bloomers like dogwood and redbud should be delayed until after the blooms have faded. After pruning, birch, walnut, and maple all bleed sap. Pruning in the fall or early winter, before sap begins to flow, helps lessen bleeding, though generally speaking, this doesn’t harm the tree.
A stringent pruning window (winter) is required for several trees, including oaks, crab apples, and elms, to prevent the spread of pests and diseases through recently made cuts. To confirm that pruning windows is appropriate in your location, check with your neighborhood extension office.
Can I prune anything in February?
Between February and March, many deciduous shrubs with summer blooms can be clipped; typically, they are plants that bloom on the growth of the current year. Buddleja davidii, Ceratostigma, Hydrangea paniculata, Lavatera, Leycesteria, Perovskia, hardy fuchsias, and deciduous Ceanothus are a few shrubs that require routine pruning.
How should hydrangeas be pruned in the spring?
You can prune hydrangeas paniculata and aborescens more severely without losing this year’s blossoms because they bloom on new wood. Although pruning is not necessary, if it is not done the plant will grow taller, with the majority of its flowers at the top.
Cut back to a healthy framework
Trim the previous year’s growth back to a strong framework that is between 30 cm and 60 cm high in the early spring. On each stem, prune to just above a pair of sound buds. For large flowers, prune back to the lowest healthy buds; less firmly for a more natural appearance or a higher plant.

Are heucheras sun or shade lovers?
For most heucheras, partial or dappled shade is ideal. Plants with darker leaves can frequently tolerate more sun, which could enhance the leaf colors. They thrive in most typical soils that are neither too moist nor too dry.
