This blog gets its name from the Katsura tree. One of my favourite trees. Walking around the garden this evening the sunlight catches the delicate leaves fluttering in the breeze, but no burnt toffee.
Time passes and I revisit the katsura trees. Thank you to David and Nadia for their comments about the similar sounding symptoms they’ve had. I’m none the wiser, sadly! According to Strouts & Winter frost damage from late or spring frosts can account for problems particularly on thin, vulnerable stems. That would fit, I suppose, except only one of my sapling katsuras was affected, the other, almost identical one, seems unaffected.
The only other katsura trees I know about locally are at Houghall Arboretum and Durham Botanic Gardens. I haven’t visited the botanic garden recently but the Houghall trees look fine.
But a closer examination of my own sickly katsura held a surprise. Scratching the bark in several places with my fingernail showed a bright green sapwood underneath. Next spring should be interesting.
I’ve uploaded some fairly large images (click on the thumbnails below) of the living and (apparently not so) dead trees.
As the title of this blog might suggest, I have a particular fondness for the Katsura tree (Cercidiphyllum japonicum). I have three in the garden, all youngsters. One is getting on for 2 or 3 metres tall, has been in for a few years (planted Nov 2007), and is looking good. Around the corner in … Continue reading “The Katsura Tree”
As the title of this blog might suggest, I have a particular fondness for the Katsura tree (Cercidiphyllum japonicum). I have three in the garden, all youngsters. One is getting on for 2 or 3 metres tall, has been in for a few years (planted Nov 2007), and is looking good.
Around the corner in the front garden there are a couple of tiny trees that I snapped up for a fiver each from Dawyck a couple of years ago. They are about 3 or 4 metres apart and have been absolutely fine since the day they were put in. I occasionally mulch with grass clippings or clear encroaching roses or beech from them, but all, in all, they’ve seemed happy.
But something has happened recently. The one on the right (click for a bigger picture) looks pretty healthy. Not a big tree but happy enough.
And then I walk about 3 metres along the flower bed to the next one. And it doesn’t look well at all.
The mush you can see around the base is old grass clippings (no fertiliser, or weed and feed), and it is kept away from the base of the sapling. Same for the healthy one.
A closer look at the leaves shows them brown and mostly dead.
So, what is wrong with this picture? Why is one alive and apparently healthy, and one is dead, or nearly so? They are only a few metres apart and have no visible differences in light, soil or moisture.
