Hi Kathy,
Thanks for your response. I think water logging is possible, clay soil The one next to it may just have been lucky so far although, apart from a week or two of good weather which we have had, the summer is turning out to be as wet as the spring was so it could go the same way. Too big to move and nowhere to put it even if I did. To think we still have a hosepipe ban!

Hi, Paul,
What was winter like where you live? Also, any chance of too much or not enough water?

Mahonia, sudden death

I have 2 Mahonia growing side by side, not sure which variety, tall upright, spikey green leaves, possibly 'winter sun' as opposed to the smaller prostrate type. Anyway one has suddenly turned brown from top to bottom in the space of just a couple of weeks. The one next to it has one branch which has done the same (I have pruned this off back to the trunk). The first one is lost but I need to know what the cause is in the hope that I can quickly take the appropriate action to save the other. No signs of any obvious pest or disease. Could it be virus, do they suffer from die back like cherries or wilt like clematis??? Any suggestions gratefuly welcomed.
Paul.

Thanks Katy.
I had already removed the leaves and disposed of them by the time I saw your reply. It was definitely Black Spot. I used a fungal pesticide after removing much of the leaves. It looks ok and will keep monitoring it. Hopefully it will recover to its former glory!

Mahonia rust?

Hi Eileen,
It's difficult to know anything for sure without seeing the problem - would it be possible for you to upload some pictures for us to have a look at? I'd be inclined to think it may be mahonia rust, as this is the most common disease faced by mahonias. The quickest way to identify this is to check the underside of the leaf, which will have brown pustules on it if this is indeed the case.
In the meantime remove all infected parts of the plant and burn them, and you might want to thin out the area to improve ventilation if this seems as though it could be a factor.
I look forward to seeing some photos, and hopefully we can get to the bottom of your problem!
Many thanks
Katy

Rose Black Spot disease

My Winter Sun was planted last autumn and looked great throughout winter and flowered even with all the snow and rain in Edinburgh. However, I have just discovered it is diseased and it looks like Rose Black Spot according to my research. Is this possible and is it curable if I act quickly? Can it spread to my spring bulbs, ivy and holly bushes planted nearby?

Uncooperative Mahonia

Hi, Paul! How frustrating! I am thinking the problem may be location. Though Mahonias are quite suited for shady conditions, there have been reports for some that if they don't get a couple of hours of sun each day, they won't flower well or at all. Also, most Mahonias like it on the dry side (if in shade, if in full sun they need moist but not sopping wet soil) so if it is in a boggy spot, that could explain the lack of flowers, too. Does this seem to fit your situation? Only other thing I could think of is something to do with planting (even though it was two years ago planting problems can manifest themselves later). Has it dropped many leaves lately? If you give it a tug, does it shift much? If so, it may need lifting, more soil around the roots to eliminate air pockets, and firmly replanted.
