| Post subject: | Neutralising soil pH |
Hello, I've been lurking this forum for a while now, so it's time to say hello! I've read an article just recently on bonsai focus http://www.bonsaifocus.com/article_read/411/bonsai-basics-how-to-fertilize.html about neutralising bonsai soil at the end of the year, because regular fertilising can increase the soil pH and be detrimental to the tree in the long term.... I don't know what to think about this, as I've not noticed any really bad effects on trees that I've not repotted for a couple of years, and I've fertilised reasonably heavily with slow release fertiliser and occasionally with seaweed. Is neutralising soil something that everyone here does annually? Does anyone have any opinions on this topic? |

Hi Gringo and welcome. I don't know of anyone doing this on a routine basis because most of us now use soil-less medium to grow in but it may be necessary to check the ph from time to time if there is a risk of imbalance. |

Most modern substrates like moler, pumice etc are around neutral PH and their free draining properties will mean that excess fertiliser will be flushed out with good watering practices. If you ensure your trees grow in mainly inorganic substrate rather than organic, soil based mixes, this should solve many problems of drainage, aeration, excess salt build up and even reduce the impact of the pesky vine weevil. |
