What can be the problem and what can I do?
If you pay attention to the native habitat of a plant, you can more easily choose the best location for it in your own landscape. In the wild, Leucothoe grows along shady stream banks, so shade, adequate water, and an acid and rich soil are part of the happiness quotient.
How and when should leucothoe alxillaris be pruned? How much sun do they need? Several suffered extensive damage this winter due to the heavy snow falls. Thank you.
This shrub can be planted in partial to full sun.
Pruning can be done any time of year, but it is best to prune in late winter or early spring before new growth appears.

I have 3 plants in the front of my house and one in my back yard. They all have black spots on their leaves. Can you give me advice.
Leucothoe is susceptible to a disease called Cylindrocladium leaf spot, caused by a fungus, and it looks like that's what yours has. Providing the plant with the environmental conditions it prefers and avoiding overhead watering are the most important measures to take. Applying a fungicide intended for ornamental plants may also help.

It doesn't appear that it is insect related. I water regularly. I think it is a blight. Leaves turn brown then stems die.
Do you know the pH of the soil? leucothoe cannot tolerate alkaline soil; it must be acidic.That and consistent watering are its critical needs. You can buy pH testing kits at any garden center. See if that is the problem.

Hi - I have a beautiful leucothoe that doesn't have the typical dark leathery green leaves. It has a lighter color leaf, new growth is a copper redish color, has the white bells, and I don't recall significant color in the fall or winter - nothing blazing red or burgundy. Graceful arching. It's relatively new in my summer shade garden (we've had it one year) that receives a great deal of sun once the leaves drop from the Norway maples during the fall season in conservation land behind the garden. I enjoy how it brings a lightness into this shade garden. I'd really like to add four matching leucothoe, however different gardening centers give different answers on what it might be. Seems that it could be the Racemosa - but not seeing brown stems yet, or Coast, or Rejoyce. I'm glad to send several photos by email if you could let me know your email address. Thank you in advance!! Amy in Massachusetts.
Unfortunately, your photos didn't come through, here.
I am unable to ID the plant. Even with seeing it, many species can only be identified through genetic sequencing.
You could always ask your local extension service, though:
I think this is an amazing shrub and would love to plant some of these in our landscape. However our landscaper is reporting these are only hardy in Zones 7 - 9. I am uncertain what zone we are in but our zip code is 80537 and we are not in the elevated part of this zip code but on the flat land just in front of the mountains. I had read somewhere that the impact of global warming is also affecting some planting zones. Your input would be appreciated.
I show you are in zone 5b. I checked three different sources for Leucothoe axillaris 'Little Flames' and one was zones 5 to 9, another was 6 to 9, and a university extension publication said 5b to 9.
So I think you are close enough to try it. Before winter sets in you can mulch it real well.
If still uncertain you can grow a couple specimens in containers that you move into the garage over winter.

Hi, I found these two plants under about 20 years of wet leaves and wayward vines and roots. After clearing out the debris, the plants are mostly horizontal. If I prune it to the main strong roots, will it grow vertically? Can I transfer the cut stems to make new babies?
You can propagate by semi-hardwood cuttings. You can rejuvenate it by cutting it back to within a few inches of the ground, though it is often used as groundcover.
