2021年2月23日 · A reliable brand of Akadama is the double red line in my experience over the past decade. There was a period of time when North America was receiving very low quality Akadama and it performed poorly. The percentage of Akadama should be adjusted for level of refinement, wether it is deciduous or conifer and just as importantly your climate!

2016年5月30日 · Akadama does break down, but it's not exactly the terrible thing that it's made out to be. As the roots colonize the pot they grow into the akadama and that extra moisture retention from the broken down akadama is a good thing. Plus akadama's ability for the roots to grow through means that more of the space in the pot is available for root growth.

2022年11月29日 · However, even with brands (I'm talking about Ryusen and Double Crane here) that heat treat their akadama at similar temperatures, like 300C, I still find differences in quality. Over the last 4 years (I know, a short bonsai career) I've used 3 brands of akadama, all to varying success. I've used Ryusen, Soukaku, and Ibaraki.

2022年3月15日 · This is what the akadama looks like now in the pots. Those little red, sand like granules in the pots are what is left of the akadama. This is what the akadama bag looked like. From what I have read and experienced, I don't think there is any regulation on processing what is called Akadama and what is shipped to the US.

2012年3月28日 · Regarding Akadama, we've been importing akadama direct from the double red line manufacturer for at least 7 years. Our recent shipment from Japan of akadama was held up by the United States Department of Agriculture for an inspection. They found organic material in the akadama such as root fibers and will not allow the shipment in.

2015年8月31日 · When akadama breaks. down, it hold more water, due to the greater surface area. So, just when the tree starts to demand more water, the akadama is providing it. Of course, if it breaks down too quickly it can hold too much water! So, that why we cut it with pumice and lava. Note: trees you regularly repot every year do great in a pure akadama mix.

2018年7月19日 · Akadama and many other clay products comes from Kaolinite clay, the primary component of which is Aluminium Silicate. In the case of akadama and other similarly colored clay products, the next most prominent component is Iron Oxide (which gives the product its orange color). Akadama is approximately 80% Aluminium Silicate and Iron Oxide.

2021年3月19日 · Ok I cant be 100% sure because I dont grow fukien tea, but you will most likely want more akadama in the mix for your hot summers if you keep it outside. I guess the big question is if its inside or outside. Not sure how low your nights get (I live on the coast south of SF) But I have a good feeling it will be OK year round outside.

2009年7月27日 · Perhaps fund a soil analysis of akadama and the Hawaiian material side by side to see if they contain the same mineral mix and have similar properties. Last edited: Jul 28, 2009 K

2012年3月28日 · From my feeble memory. Double Red Line Akadama is fired or heated to 800° C. That will kill any organism in it. Again, the importer needs to have a conversation with the Dept. of Agriculture supervisor at the port of entry. Find out …
