My Inkberry Holly bushes have developed dark spots on the leaves that ultimately turn completely dark brown or black. The branch supporting those leaves apparently dies. This has occured with bushes in close proximity with one being diseased and the other 6 feet away with no problem. My landscaping had 22 of these bushes. I have 14 remaining but some starting to show the disease. Could you please tell me what caused this problem and the cure?
I have an Inkberry holly, which is rather bare at the bottom. How can I get it to fill in and how and when do I trim it? Also, I would like tips for the general care of it, please.

I’m having a terrible time finding out what inkberry cultivars are male and female and which flower at the same time so the berries can be produced. I seem to be constantly finding vague or contradictory information. I ‘think “Nigra” is female and “Nordic” is male (not positive) but I know from winterberries that even when you’re sure that you have a male and female, it doesn’t mean bloom times will overlap. Any help? Thanks!
Yes, lot's of conflicting information when it comes to Inkberry cultivators.
My research shows that both Nordic and Nigra are male.
Female cultivators to look for; Alba, Leucocarpa, Ivory Queen and Compacta.
Made some calls around today and seems like the "Nigra" is for sure female. Also found that Michael Dirr's book on woody plants lists "Nigra" as female.
Would love to know if Nordic flowers at a similar time. Might just risk it.
Why doesn't anyone sell paired m/f plants???
Legginess and loss of leaves at the bottom often happens as inkberry bushes age. This can be corrected by rejuvenation pruning- pruning the entire bush down to 12-18 inches off the ground when the inkberry is dormant. The best time is in winter or early spring. In coming years, it can be trimmed back by about 1/3 whenever necessary.
Moving a well established shrub can be done, but will need to be planned.
Since the plant will lose it's fine feeder roots you will need to root prune the plant in the fall to prepare it for a move in early spring.
