Hellebores Planting advice

Planting advice for Hellebore pot plants

Please allow some light and air into your plants immediately and keep them in a cool light place. Ensure that plants are kept moist at all times and plant them as soon as possible after receiving them.

Prepare the soil well: dig over an area, add some compost or well-rotted manure and then plant them. Take care not to damage the roots and gently firm the soil around the plant. Keep the area around them weed free.

Always water your plants in when you plant them either in a pot or in the garden. Remember hellebores are hardy plants and so they should be kept outside, not in a greenhouse or under cover.

Planting advice for Hellebore plug plants

Please allow some light and air into your plants immediately and keep them in a cool light place. Ensure that the plug plants are kept moist at all times and plant them as soon as possible after receiving them.

If possible, plant each plug in a 1 or 2 litre sized deep pot or container for this growing season so that they establish well before planting them out. Keep them in cool semi-shade – don’t put them in a greenhouse or conservatory.

Once they have rooted down into the pots they will be ready to plant into the garden in the autumn or spring. Prepare the soil well: dig over an area, add some compost or well-rotted manure and then plant them. Take care not to damage the roots and gently firm the soil around the plant. Keep the area around them weed free.

Planting advice for Hellebore seeds

The seeds are freshly collected and are ready for immediate sowing. Sow them within two weeks of receiving them. Use suitable seed compost and push them into the surface gently so that they are just below the surface of the soil, then cover with a shallow layer of horticultural grit or similar. Water them in using a watering can with a rose on so they are sprinkled with water rather than drowned.

Cover pots with netting to protect the seeds from birds and mice. Protect against slugs when seedlings first appear.

Hellebores are hardy and so don’t need protecting from frost. Leave them outside in partial shade over the winter and seedlings will appear in December/January.

Where to plant hellebores

Hellebores thrive in dappled shade in soil that is well cultivated, fertile and always moist.

Compost and feed

Hellebores are hungry plants. Use a general purpose, free draining compost or well-rotted manure when planting. The main growing periods are during the Spring and Autumn so mulching is very beneficial at these times. A general purpose fertilizer can be applied in late winter. Liquid feed during the growing season is also worthwhile.

Leaves

Hellebore leaves are ‘evergreen’ but do eventually look past their best, usually in late Winter. They can then be cut off and new growth will take place. We advise leaving the leaves on as long as they look green and healthy.

Occasional problems

Black Spot: Helleborus nigerplants sometime suffer from fungal disease which causes black patches on their leaves. The easiest way to prevent this or treat if already present is to spray with a fungicide like Liquid Copper or something like Roseclear at the same time as you treat your roses.

Aphids: Sometimes aphids enjoy feeding on Hellebores. Use an appropriate pesticide from your local garden centre or hardware store to prevent an infestation.

Please note:
Hellebores can cause skin irritation and are harmful if eaten.
