| Since I was moving, I had to move 2 large Hellebore Foetidus plants in July to a place where it was sunnier than they were used to. They're now in a nice shady bed but their leaves have black streakingand look terrible. Is this a virus? What should I do?

| Is it all black, or just the old growth and the leaves at the bottom part of the stem. It's fairly normal for the old flowered stems to rot away, new stems should have pushed through to replace them and even on them you'll get some leaf loss. Is there air round the crown. How old is the plant, did you plant it as a seedling or as a mature plant. I find if you plant them big, ie already at flowering size, they don't live long. They're far better planted very small and will grow very quickly in situ. 2nd year from seed will flower on a single or double stem, following year will have 10-15 stems(in rich ground) In the light of this they're actually better in really scruffy soil with no goodness at all. In the wild they grow in scree and on cliff faces with only cracks to grow in. There they grow to 10-15" and flower like crazy. In the garden bed they can be 30" and very lush...still flower like crazy, from december. There's lots of old posting here, have a browse and see if you can work out your situation.

| I moved it as a large plant. It was in a sunnier place before and started to get black lines around the edges of the leaves.The whole leaves aren't black. I've never had this before. Hedy |

| I should cross my fingers and hope it's just settling in. Collect and sow seed next year though, I'm sure you'll have new healthy plants within a couple of years. Cheers Greenmanplants. |

| This could be Black spot, Coniothyrium hellebori. It attacks the foliage stems and flowers. Plants growing poorly with poor ventilation are most susceptible. Black or brown blotches appear and spread to whole leaves and eventually whole plants. Cut off all blackened growth or leaves with blackened bits. Cut through the stems near ground level. Take the trouble to cut through the partly affected stems first in good green growth. Gently pull off any blackened stems at the crown, also removing old rubbish near the crown(last years stem cuttings etc). Clean your cutting implement after cutting any badly affected stems. Burn or dispose of the leaves cut off. Thin the leaves out to let the air flow, the plant doesn't need all the leaves through the winter, especially remove those trailing on the ground or already damaged as this is how the fungus gets in. If you can, get a systemic fungicide....Whatever is still permissable where you are, I'm bot going to make any suggestions here as I'm bound to be wrong for your local regulations. Follow the instructions and water the crown and surrounding ground area with the fungicide mix. Spray to run off on both sides of the remaining leaves, ie give it a good dousing. If this doesn't clear it up, try a repeat dousing. Finally, be prepared to dig out any very badly affected plant and burn it if it doesn't clear up. Give the ground a good soak of fungicide and don't replant in the same spot for a year. I'm fairly sure it won't come to all that. Cheers Greenmanplants |
