Well said. TDS is the first thing to consider. Adjusting the PH of high TDS water only works in the short term. If you were to adjust a Ph 7.5 to 6.5 where the TDS is high let’s say 250ppm the adjusted waters Ph would slowly increase again. Try it in a barrel. The only way to reduce high TDS effectively is to pass it through a Reverse Osmosis unit and add Cal mag or similar, possibly you tap water to bring the TDS back up to around 75ppm. (That’s what I use ). Reverse osmosis is a very wasteful system so can be expensive on the water bill. Reverse Osmosis water is stripped bare and has almost zero TDS or iron and magnesium etc. Hence the need to bring it back to being usable for our plants. So here I pass our water of TDS 255 ppm and a ph of 7.4 through a reverse osmosis unit, it gives me water of TDS 8, Ph 6.5. I mix three parts Reverse osmosis water with one part of carbon filtered tap water. I then have a very useable water of around TDS 75 PPM and a PH of around 6.8. As I said before this can have a low Magnesium and Iron content so I supplement with the addition of Cal mag once or twice a year. If you want really good quality container grown plants (Bonsai) this will the best thing you could do for your trees if your suffering from poor water quality and or salt build ups. Reverse osmosis water can be a little wasteful and expensive if on a water meter but I wouldn’t hesitate to recommend it to anyone with Bonsai trees of quality. Maybe just make enough for those special trees. For me I wouldn’t be without it.

This vid has created more questions than answers. It's actually annoying to watch, the whole time I just want one question he's basically asking himself answered. What does a "harsh" fertilizer look like on npk scale? Is it harsh because over application? Or is it harsh because the combo of strong npk and hard water? What is excessive fertilizing in this regards? What does easing off the fertilizer mean, instead of weekly, every 10 days, 2 weeks? Most people's water is alkaline, what's the solution? RO water system? Treated tank you pull water from? Ph buffer seems like a product that once you miss a dose you revert back to 0 basically making all the previous treatments useless, is this true? How do you flush the salts out of a bonsai pot/fertilizer? Is there a scheduled maintenance for this flushing you can do a few times a year? Are there soil additives that can be used to mitigate this? Probably good to walk into a conversation on PH with an agenda next time, this was too "winged it" to be useful.

leant so much from Peter Warren, he's a proper bonsai soldier.

Great horticultural video. Salinity is super important and not very many people actually talk about it

Very beautiful

Sorry, but does the tree in the background look like a tree in nature? It looks exactly like an overgrown stump from a tree)))

We continue to wait for subtitles in Russian. It is a shame that you cannot fully enjoy this wonderful content due to the fact that the knowledge of those who are engaged in setting up videos is much weaker than those who come out with useful information about bonsai.
