Hellebore

Hellebores are quite drought tolerant and prefer dry conditions. Occasionally, during periods of extreme heat and drought, they will benefit from an occasional deep soaking. Generally, they require little to no supplemental water, except during extremely dry periods and only when the plants show signs of stress such as wilting or browning of the foliage.

Hellebores prefer partial to full shade. They can tolerate full sun in the cooler climates and prefer dappled sun, especially in hotter climates. When possible, give Hellebore plants protection from hot afternoon sun. Full sun exposure can cause the foliage to burn and the flower buds to drop.

They thrive in US Department of Agriculture zones 4 through 8 and prefer temperatures ranging from 20 degrees Fahrenheit up to 75 degrees Fahrenheit. In cooler zones, they may go dormant over summer and come back with the cooler fall temperatures.

They prefer higher humidity levels, but will tolerate average household humidity. If temperatures remain high indoors, it's best to increase the humidity by running a humidifier or misting the plants with a water bottle.

Hellebores prefer moist but well-drained, neutral to slightly acidic soil. They do best in a light, sandy, humus soil with good drainage. If your soil is clay-like or heavy, you will need to amend it with sand, peat moss, or compost to enhance drainage.

Hellebores do not need much fertilizer, but a light application of a balanced slow release fertilizer in spring and summer can be helpful. Avoid fertilizers high in phosphorus or nitrogen as these can burn the delicate root system. Organic fertilizers can also be used to provide the nutrients the Hellebore need.

Though Hellebores are relatively pest-free, they can occasionally become infected with aphids, mealybugs and spider mites. Aphids tend to leave a sticky honeydew, which is a sign of an infestation. Mealybugs tend to leave powdery, white speckles on the foliage and stems. To remove pests, wipe the foliage with a wet cloth. If the populations are large, it may be necessary to use an insecticidal soap to remove the pests.

Hellebores don't need to be repotted very often as they tend to be relatively slow-growing and can be happy in the same pot for many years. However, if you notice the plant's roots crowding the container, you can repot it into something a little larger. You can do this anytime during the spring or summer.

Hellebores are naturally low-maintenance. However, you may find that removing spent flower heads will help to maintain a tidy appearance and avoid overcrowding of foliage. Deadheading also helps to prevent the energy of the plant from going into seed production and encourages more blooms. Also, if the leaves become yellow or brown you can prune them back to promote new growth.

Mulching is essential for hellebores, especially if planted in sandy soils. It helps retain moisture and protect the roots from extreme sun and heat during summer months. Use organic mulch such as wood chips, bark, compost or leaves when mulching around hellebores.

Hellebores can be propagated either by division of the clumps or by seed. Division of clumps is the simplest and most successful way to increase the number of plants. You can either dig up the entire clump or carefully dig around and lift out a section of the clump. In the case of seed-propagation, the best time to sow the seeds is in mid-summer, as it can take up to a year for some seeds to germinate.

Hellebores are quite sturdy and need little or no support in their normal growing environment. Though, if you are growing them in a windy area or plan to move them around, you may consider putting a cage around them for additional support.

Hellebores do not require much of a rest period but they do need to be kept cool and dry in the winter months. If kept too warm, they will not bloom. Keep their soil on the dry-side and do not water as frequently as you would in the spring and summer months.
