Japanese White Pine – Over watering problem solved
This Japanese White Pine was brought to me to sort out problems caused by overwatering. The moss had got like a thick carpet and developed caviar like dark spheres.
On investigating the spheres turned out to be a form of cyanobacteria – Nostoc is a genus of cyanobacteria found in a variety of environmental niches that forms colonies composed of filaments of moniliform cells in a gelatinous sheath.” en.wikipedia.org/wiki/Nostoc
While it is not harmfull to the tree, it is an indication of the pot being too wet. The watering needs to be reduced, pines like it on the dry side.
These pods should be removed and watering regime improved, to achieve this and make it easier for beginners and the not so experienced bonsai enthusiasts and owners the moss is removed completely and also remove a couple of centimetres of the soil surface soil and give it a top dressing of fine grade akadama.
This strategy would make it visually possible to see when the bonsai soil is wet and when its drying out. The akadama top dressing becomes dark chocolate colour when wet and lighter colour when its starting to dry out, where as with the moss it is not possible to tell the difference, resulting in over watering.
My solution makes it easier for a more controlled watering regime and avoid over watering.
