Mahonia, sudden death

Mahonia, sudden death

Question from Shoot User
1680 1
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.

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

      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!
      Paul.
