Can anyone tell me the way to make good bonsai soil?
Whats the question? Slow down if the dog iis still there, who cares about the truck. Only go as fast as you feel comfortable, dont have to prove anything to anyone.
Sounds like you're just not ready for motorcycle riding.
OK, try this. YOU are in the front of that line,THEY have to follow you, especially the truck driver knows this, ride at a speed you can be comfortable with until you can find a place to yield. HE will be at fault if he hits you, something he DOESNT WANT to happen. but if he intimidates you into crashing,it's your fault. A farm road? Paved or unpaved? Get out and ride more. 25 years ago I taught my GF to ride, during the day,I couldn't get her to speed up, at nite I couldn't get her to slow down.
Yes this answer varies dependent on many factors including species of tree and preference. But general rule of thumb is that it needs to drain well but still absorb water and release it slowly. Typical substrates used are usual mixes of Lava rock, Pine Bark, Perlite, grit, ect. Many enthusiasts prefer 100% lava rock or Fired Clay Like Akadama. the high end bonsai soil is usualky either lava rock or made of the same stuff as a product called Turface that is super cheap. The Lava rock will drain well and absorb water nicely I prefer a mix of 65% Lava Rock, 20 Perlite, and 15% Grit. Of course we are still going to use a slow release bonsai soil to make sure the tree get's enough nutrients in it's small container. But the fast draining soil will prevent the tree from getting root rot. That is probably the #1 killer of beginner bonsai trees. Also Make sure the pot has good drainage holes.
