Title: Black pine root/repotting question
Post by: Josh on April 08, 2012, 10:16 PM
I recently repotted a nursery JBP from a garden to bonsai pot into modified "Boon mix" (1/4 akadama, 1/4 pumice, 1/4 lava and 1/4 of general purpose bonsai soil mix I have used for years and wanted to use up).  Good rootball, pleased with the repot.  Tree is 15-20 years old, very healthy.  Needle pluck before repot, limited candle shortenning.  Placed sphagnum on top to limit quick drying, it has been 60-80 degrees in South Dakota this last two weeks.

After looking at my job, I decided I repotted rootball too high, and I chose to repot to lower the nebari.  This would be 10 days following initial repot.  When I removed the sphagnum moss, I observed small clear crystals (looked like table salt) at the soil line on surface roots.  What might this be?  Sap from cut edges of roots?  Something else?  Tree remains healthy in appearance.

Thanks, Josh
