White deposits on pots

Q: I have noticed that on many of my brown (unglazed) pots and also on other colours, a white deposit cakes hard on the edges. Can you tell me how to avoid this, or if there is a substance with which to clean it?

A: The white deposit on your pots can be caused by either a chemical in the clay coming to the surface or by chemicals in our water or by fertilisers. It is possible to establish exactly what it is and possibly to provide another chemical to dissolve it, but in all probability the cleaner would kill your tree, so you have to resort to mechanical methods. On glazed pots a razor blade or scalpel can be used to scrape the deposit off, while on unglazed pots fine abrasive paper (glass or sandpaper) will easily remove the ugly marks..

Random Bonsai Tip

So much time is spent on striving towards perfection in the foliage area of trees but little contemplation goes into the area around the nebari. Consider planting your tree at different heights in the pot which might enhance the existing taper and roots. If your tree lacks roots use moss mounded in such a way to suggest underlying roots, or you can even use sticks of similar appearance to the wood of the tree as 'fake' roots until you are able to coerce roots to fill the void. Use appropriate gravel to complete the scene.
