Early spring or late winter, just as the new growth starts to show, is the perfect time to prune a hellebore plant. This new growth ought to emerge from the earth as little stalks. These stalks ought to still be encircled by a ring of the large leaves from the previous year. The old leaves may very likely have been harmed by the winter’s cold and appear a little worn-down.
These old leaves can be removed as soon as the new growth develops by chopping them off at the base. You don’t need to prune your older foliage as long as it is healthy and undamaged, but once the new growth begins to leaf out, you’ll need to make room for it by pruning the older growth. If you wait too long to remove the old growth, it will tangle up with the new growth and be much more difficult to remove.
Hellebores can be eaten by snails and slugs as well, and the thick foliage provides them with wet, hidden hiding places.
Should I prune my hellebores after they bloom?
Before the flower pods split, I always remove all of the flower stems. Last but not least, it’s common advice to divide your hardy perennials every three years and replant the healthiest pieces in better soil.
Should you trim back the hellebore plants?
Not only galanthus lovers are experiencing a fever in the garden at this time of year. Fans of hellebore still adore these wild plants because they provide something delicate to find in the dappled light of early spring.
Hellebores (Helleborus), a member of the Ranunculaceae or buttercup family, have its origins in the Balkans. Their blossoming season lasts from December till the beginning of May.
At Great Comp Garden in Kent, William Dyson has been raising hellebores for 40 years. According to him, lenten rose varieties can be found practically everywhere that is wet, well-drained, and has dappled shadow. In our woodland, we have hundreds of them growing.
Hellebore pruning and maintenance
In order to stop black spot spores from infecting the new growth that appears in the new year, we remove old leaves from our plants in the early days of December. Even though hellebores are evergreen, they don’t require pruning, and in my own yard, I have a few clumps of double-flowered hybrids that have never been cut back.
In order to avoid skin irritation from the hellebore’s sap, William encourages gardeners to prune their hellebores while wearing gloves. Look out for any new growth while wearing gloves and holding a pair of secateurs. Cut off the growth from the previous year at the plant’s base when it emerges.
In order to prevent blossom droop, hellebore growers should place their plants in a forest area that offers protection from the elements and receives adequate dappled sunshine. It’s also advisable to urge plants to face the sun.
When asked why hellebores droop, William responds, “I’m frequently questioned. It seems that they do this as a defense mechanism against rain, sleet, and snow. Flowers produced through hybridization with Helleborus niger won’t droop since this species faces outwards rather than drooping.
Hellebore varieties
William emphasizes that there are many types available, making it worthwhile to select your hellebores not only for their flowers but also for their leaves.” Helleborus niger ‘Snowdrift’ and Helleborus hybridus ‘Pink Ballerina’ have been added this year, expanding the hellebore collection in our core forest areas.
The latter is an orientalis hybrid that blooms in profusion from January through March with several completely double, light pink flowers. These plants have incredibly unique foliage that is captivating all year long.
William advises a visit to Ashwood Nurseries in the West Midlands if you’re looking to buy a hellebore.”
The magnificent plants at Ashwood Nurseries are owned by John Massey VMH, who has been producing hellebores for decades and is the global expert on them. I suggest going to witness his hybrids as well as the owner’s own creation, “John’s Garden.”

Are hellebores intended to be deadheaded?
As the flower buds begin to appear, late winter or early spring, depending on your growth zone, is a good time to remove the old, dead leaves from the plant.
You run the risk of destroying the lovely blooms if you wait until the plant has fully bloomed.
Older, decomposing leaves can also serve as a breeding ground for bacteria and fungal spores that can harm surrounding plants, including lenten rose bushes.
As soon as you see any sick growth, you should trim it to prevent it from spreading to nearby plants.
Following pruning, fresh leaves will emerge from the core of the plant and spread out as they get bigger.
Hellebore pruning is a simple process, but you’ll need the correct equipment. Use razor-sharp bypass pruners at all times.
Additionally, hellebores have tiny thorns, thus it is advised to use sturdy gardening gloves.
Continue to remove any broken leaves as the growing season goes on to give the plant a neater appearance.
Hellebores are forgiving plants, unlike some plants that are quite particular about when you should prune them. It won’t care if you keep it clean all year round!
Although hellebores are said to bloom in the late winter and early spring, they are evergreen all year round, so I also find myself cutting them in the summer.
Deadheading hellebores flowers
I frequently get the inquiry, “Should I deadhead hellebores? The simple answer is yes, but it will be more enjoyable to learn the lengthy answer.
You’ll be surprised by how long a hellebore plant’s blossoms last. Some of mine have been in bloom for months. But everything nice has an end.
It’s simple to deadhead hellebores. Simply cut off the old flower stems when they begin to wilt. Cut them back to the plant’s root system.
The Bear’s Foot Hellebore (H. foetidus), commonly referred to as “stinking hellebore,” is an exception. You should leave the stems on the plant since they contain the bloom buds for the following season.
By deadheading their blossoms, hellebores can focus their resources on developing new blooms rather than trying to preserve their fading flowers.
Some Hellebore plants produce flower clusters that tower over the rest of the plants. On mature plants, these stems have a tendency to become quite heavy and droopy.
Deadheading hellebores with all of their stems is a good idea when their tips become too straggly.
Do hellebores return annually?
Hybrid hellebores can tolerate a broad range of growth situations, but they thrive in rich, moist, but well-draining soil when planted in partial shade. Hellebores are rather simple to grow and, as perennials, will bloom for a number of years.
Hellebore planting tips:
- To properly enjoy the downward-facing blooms of hellebore plants, many gardeners prefer to put them on a hillside or in raised flower beds. Here’s a great illustration of this planting technique: A box of winter jewels.
- Shake off the potting soil and untie any constrained roots before transplanting hellebores straight from their nursery containers.
- Planting hellebores too deeply can prevent them from producing flowers, so take care. Make sure the plant’s crown is barely visible above the dirt.
When may hellebores be divided in the UK?
Each year, cover the soil surrounding plants with a thick layer of mulch and top it off as needed (for more information, see our guide to mulching).
An organic mulch, like homemade compost, is a fantastic way to enrich your soil with nutrients and beneficial microorganisms. Additionally, it conserves moisture and prevents weed germination.
Overwintering
Most of the commonly seen hellebores are resilient and don’t require further protection, notably the Oriental hybrids (Helleborushybridus).
H. niger dislikes sitting in cold, damp soil, therefore it need great drainage over the winter. Therefore, it is preferable to plant it in a container and maintain it in a protected area all winter (such as at the base of a south- or west-facing house wall)
H. thibetanus, a species that dislikes the wintertime rain, or H. lividus, a species that is only moderately hardy, do best when overwintered in a cool greenhouse, porch, or coldframe.
Caring for older plants
Helleborushybridus are often long-lived plants when planted in the right environment. Divide huge, aged clumps in the fall or spring to revitalize them.
Some other hellebores have a lifespan of five years or less. In late April, prune old flowers and leaves to promote fresh growth.
Oriental hybrids
To guarantee that the nodding flowers are fully shown, trim back the old leaves of Helleborus x hybridus in late winter or early spring. Additionally, this aids in reducing Hellebore leaf spot illness
These hellebores frequently self-seed, and the progeny can develop and cover the parent plant. To prevent unwanted seedlings, dig up and relocate seedlings before they grow too big or destroy seed pods before they open by cutting stems at the base.
Other hellebores
Remove the old flower stems and wilted leaves in late April after the flowers have faded to encourage new growth from the roots. If you want plants to self-seed, leave some seedpods.
By division
Most hellebores can be easily propagated by digging up the clumps and splitting them (for more information, see our guide on dividing perennials). Though you may also apply it in spring, immediately following flowering, early autumn is the best time to accomplish this.
Place the smaller clumps you have created so the first roots are 2.5 cm (1 in) below the soil’s surface when you replant them. For the initial growth season, water often until the plant is well-established.
Helleborus argutifolius, H. foetidus, H. lividus, and H. sternii can all be grown from seed but are not recommended for division.
Are hellebores suitable for pots?
Around the holidays, when it is offered as a Christmas rose, container-grown hellebore may be seen. These are frequently used for decorations before being let to rot or are simply thrown away, along with other seasonal plants like poinsettia. However, there is no need to allow your potted hellebore to deteriorate. Until you’re ready to plant it outside, you may either keep it in a pot and enjoy it both indoors and outside all year long.
Hellebores require rich, well-drained soil, so make sure to select a pot with drainage holes and plant them in rich, organic potting soil or amend their current soil with compost. Additionally, as hellebore plants dislike being moved, a large container should be selected. Give your plant room to flourish because moving stress can be harmful. Given that the roots typically grow downward, the pot’s depth is very crucial.
Place your potted hellebores where they will receive the most sunlight over the winter and early spring. As the temperature rises, a little shade will be welcome. In the winter, hellebore prefers cooler temperatures, so make sure it receives sun without getting too hot. Find an elevated spot for your container-grown hellebore so you can completely enjoy it. The flowers have a tendency to fall downward.
Hellebore thrives when grown in the ground outside, but if you’re short on space or just want to enjoy these wonderful blossoms indoors, you should be able to make it happy in a container.
Whether hellebores self-seed.
Hellebores are dependable and simple to grow in any garden. Depending on the type, most hellebores are low-growing plants that grow to a height of around 3-.5m and bloom from December through May. Hellebores offer a broad variety of flower colors, including several with lovely speckles inside the petals. These colors include all shades of red, crimson, delicate pinks, various shades of yellow, and white. Helleborus argutifolius, often known as the Corsican hellebore, is a brilliant green variation of the plant.
Hellebores are a rapidly evolving group of plants due to the constant development of new hybrids and the availability of dozens of exquisite variations with richer colors, double petals, and even more erect flower heads.
In order to distinguish it from Helleborus Niger, the Christmas rose, which blooms earlier, Helleborus hybridus, formerly known as H. orientalis, is the kind of hellebore that is most frequently offered for sale.
H. ‘Christmas Carol,’ seen bottom right, and H. ‘Verboom beauty,’ which begins to bloom in December, are two of the earliest flowering varieties. Many Hellebores will self-seed in the garden and grow into clumps like those shown in the top left photograph. The majority of the common Helleborus types are modest, growing up to about half a meter, making them ideal for front-of-the-border plants, woodland settings, and as ground cover. Hellebores are perfect for growing on a bank because they have delicate blossoms and because many types have nodding flower heads that hang down. Although they can become semi-evergreen or deciduous in harsh winters, hellebores are typically evergreen.
The more unique Hellebore is H. “Corsican,” which, as its name suggests, is from Corsica. It is green with leathery leaves, evergreen, and taller than the other Hellebores at around 1.2 meters (4 feet), as shown in the illustration in the center.
Will hellebores grow in number?
A hellebore will produce anywhere between two and ten divided plants. Plant the divided plants as soon as possible, taking care to prevent the roots from drying out. Plant them in well-prepared, well-drained soil.
