[IBC] oak in a bad situation
A member from my club collected a Kellog Oak in January, and gave it to me
in early march. It is in a 5 gallon bucket with its natural soil. It has been doin great. Leaves have been booming (its a diciduous tree), and new shoots have been showing. Several days ago however, I noticed many leaves are turning yellow, and brown at the tips. It has been very warm the past week, and I ussually keep it in the full sun. I moved it into a more shady area when I noticed the problem, but it is getting worse. Any thoughts what it could be, or how I could treat it? Thanks so much. - Colin Horn Orinda, CA __________________________________________________ _______________ MSN 8 with e-mail virus protection service: 2 months FREE* http://join.msn.com/?page=features/virus ************************************************** ****************************** ++++Sponsored, in part, by Mike Page ++++ ************************************************** ****************************** -- The IBC HOME PAGE & FAQ: http://www.internetbonsaiclub.org/ -- +++++ Questions?

[IBC] oak in a bad situation
Natural soil? That could be the problem. It should really have gone into
well a drained, open soil mixture. Blocked drainage holes are another possibility that I have nearly lost an oak tree to in the past. Lift the bucket and check its weight. If it feels very heavy make some new holes around the bottom and sides of the bucket. If water floods out then you are likely to have rotted off many of the roots. Mine was revived by a complete repot (in the height of summer!) washing all soil off, cutting away dead roots and placing on a heated cable. It is now, six years later, a showable tree.

[IBC] oak in a bad situation
Good advice from Kevin & Shelly. I have one other area of concern. Since you
are in California and using regular soil, I wonder if you might have an oak infested with Sudden Oak Death Syndrome caused by the microscopic organism known as Phytophthora ramorum, part of a group funguslike organisms known as water molds. If this is the case, you need to carefully destroy the oak and its soil to prevent contaminating other trees. I suggest taking it to your county agricultural extension agent for examination and diagnosis. Hope I'm wrong, but better safe than sorry!

And natural soil is a big mistake. The only quick solution is much more drainage, and if that doesn't work a repot will have to be done . . . which will be much harder on the tree than drilling a bunch of holes in it's current container. If you wind up repotting, I'd suggest straight coarse builders sand.
