i want to know what type of soil is best for a beginner.how to make it at home.there are lot of stores who sell on internet,because i am living in Pakistan no such facility available here.please help
So much the better. It used to be thought that sharp edges would 'stimulate' roots to split or divide and therefore stimulate the branches to mimic the roots and divide as well. I believe that this has proven to be yet another of the many bonsai myths. Still, I prefer irregularly shaped material to smooth ones because they don't pack together as easily as smoother material. The Pumice you have shown would be acceptable if sized appropriately.gravel i have is not round but with sharp edges.
I don't have any knowledge of this material but there is nothing magical about Pine bark, in fact some growers don't like it. Growers on the west coast (of America) often use Fir bark instead.but i don't have pine bark as i am living in the Gujranwala city of Pakistan no pine here.can i use shesham bark.
Since your climate is that extreme it would be prudent to include some organic material in your mix.its very hot now a days in Pakistan about 40 C and direct sunlight can burn skin.i have protected my bonsai in green shades.they really need soil that can hold moist in it.
I'm not sure that Almond Shell will serve the purpose. Do you by any chance mean Almond Hulls? I have never experimented with this material so I'm not sure. It might be worth a try.what you think about almond shell. it can be used instead of pine bark? if you allow me i will try it.
If so I would recommend a soil 50% organic and 50% pumice or other porous rock. That should help maintain moisture.its very hot now a days in Pakistan about 40 C and direct sunlight can burn skin.i have protected my bonsai in green shades.they really need soil that can hold moist in it.
