Helleborus Niger

Helleborus Niger

The best place to plant a Helleborus is in a sheltered location that does not receive afternoon sun.
This is because morning sun helps these plants dry off. The more moist the soil, the more sun the
plant can tolerate.

Choose a location for your Helleborus that is sufficiently and consistently moist: not too dry but certainly
not too wet. Mulching with bark often helps, too: this prevents a complete drying out and will reduce the
impact of cold temperatures on your plant.

The Helleborus prefers rich, well-drained loamy soil high in humus yet it will thrive in most garden soils.
It will not do as well, however, in a poor dry soil. If you want to transplant a Helleborus from indoors to
your garden, do this after the winter once the ground has thawed. Before planting, water the root ball
thoroughly. Wondering what other plants would combine nicely with the Helleborus? Good neighbours
that flower during the same period would include the Snowdrop, Primrose, Epimedium, Winter aconite,
Anemone blanda, Squill, Witch Hazel and Sweet box. A combination with roses would be another
good option since they have a different flowering period.
Side dressing your Helleborus is highly recommended, and this should be done early in the autumn (October).
Use an organic fertiliser such as cow manure plus lime for a good flowering result next year. Repeat this procedure
early in the spring (March/April).
What should you do when new leaves appear in the spring? If you have an H. niger or H. orientalis variety, trim all
the old leaves away; for other varieties, trim off only the damaged leaves. Also trim off any old flowers because these
can attract aphids.
It is not advisable to transplant a Helleborus once it is established.
What if you have a Helleborus outside in a pot or tub? Before a lengthy period of frost, place it in a very cool place since
plants in pots are very susceptible to damage from frost (even light frost). Repot your Helleborus every year (or as needed)
into a larger pot with fresh soil. This should be done before the new leaves emerge.
Pests and diseases
Are there black spots on the leaves? This could be leaf spot disease. Remove all diseased leaves and dispose of them in
a refuse container for recycling kitchen and garden waste. If this disease is a major problem, consult with a specialist from
a garden centre, etc. about the best way to protect the plant.
Problems with slugs? Scatter some shells around the Helleborus or check with your garden centre about ways of keeping
slugs away. Are there aphids on your plant? Planting garlic bulbs near the plant or pouring garlic water next to the Helleborus
is often effective for controlling aphids. If this fails to work, consult with your garden centre or other specialist.

The Helleboris is proposed in the growing pot with a diameter of 17 cm,
the height of the plant is 40 cm.
