Auxin Posted November 1, 2002 After seeing Torsten strongly advocate Course Sharp Sand (CSS) so many times I was starting to think he had invested in course sharp sand manufacturing plants and was trying to boost his profits, but I finally tried it and IT DOES WORK QUITE GOOD! I got some acacia seeds from him and soaked 4 until they swelled and planted them in 1/2 cactus soil 1/2 potting soil, none sprouted. I soaked 4 more and planted them in cactus soil, one sprouted. I then found CSS so I soaked 5 seeds and planted them in 70% CSS 30% potting soil, ALL FIVE SPROUTED! So when Torsten talks about the wonders of course sharp sand listen to him (and dont use cactus soil as a 'substitute'.) Now the fun part starts, I get to spend 1/4 of my remaining life span turning these cute little seedlings into superb tropical bonsai. Share this post Link to post Share on other sites
waterdragon Posted November 2, 2002 i'm lucky that i took his advice some time ago, lucky also that when i go up into the hills seeking sapphires that a byproduct of the sieving is coarse sharp sand. the stuff is indispensible when putting soil mixes together, excellent drainage.

planthelper Posted November 2, 2002 hi, i mix me river gravel from leftovers when i go fossicking aswell. yes me potting mix contains at times traces of gold, platinum gemstones everything , bla, bla to just cut the crap. i like old vulcano stuff too. seaweed ( kelp and so on ) contains a lot of elements aswell... the magic here is not only good drainage, but the encludence of all those hard to get minerals... those which are absent in normal potting mix!
