Guest Posts: n/a	sick deshojo The leaves on one of my deshojo maples are begining to turn transparent, and in some cases they are turning black at the edges. The tree was taken as an air layer about two years ago, and is kept in semi shade, but during mid afternoon will receive full sun. The current temperature during the day is about 14 deg. C, and between 2 and 5 deg C at night. I feed the tree every two weeks using a high nitrogen fertiliser, and the soil is kept moist. Any ideas on why the leaves are acting this way ?

Are you using the fertilizer at roughly houseplant strength, or at a much greater concentration? __________________ In love with trees

Why not cut out the fert entirely and see if conditions improve? then you can try a reduced strength at lesser intervals. __________________ Want to be a seller on bonsaiAUCTIONS?

To much fertilizer killed a lot of leafs, but after a while it get's better. __________________ ----------------------------------------------------------------------------------------------- Bonsai Pot Signatures - http://www.yamadori.nl/Bonsai_Schalen.htm NEW BOOK 'Bonsai Potters' - http://www.yamadori.nl/Bonsai_Potters.htm -----------------------------------------------------------------------------------------------
