Juniperus communis Alpina - problem

Post  rolandp on Tue Mar 23, 2010 9:21 am

Hi all.

I hope that some of you can help me with the problem whit my Juniperus communis Alpina.

The tree was designed last year in September and was very healthy until now. First some new buds on the top of the tree begun to turning brown, now some additional small brunches and buds are turning brown as well.

Picture 1: the tree in 2009/10



Picture 2: the tree in 2010/03



If someone had some similar issue or has some ideas what the problem could be please let me know. Especially what are the possible steps to help the tree to survive.

Thanks and best regards, Roland

The droopy needles and twigs indicate to me that it is a root problem.

Is the soil damp all the time? That could mean that the roots aren't functioning -- unless it's simply that you've watered too often (or had a very wet winter).

(It could also be a scale infestation -- but there would have to be a LOT of them.)

It looks like you are suffering the same problem that we do with J communis. They survive collection and then take 2 to 3 years to die. They do this with such predictability that most people in the UK have given up collecting them.

We recently heard that there is a fungal infection that most trees in the wild cope with but it kills them after collection. The post is here http://ibonsaiclub.forumotion.com/bonsai-f1/juniperus-communis-yamadori-2007-t2466.htm#24655
