Hello, I recently for the first time just repotted all my trees that were in training over the last 10-15 years from wooden boxes and turface as a soil medium to bonsai pots and clay king. It was mandatory for these trees as it was time to give them the “GOOD STUFF”, as I would call it. But I have about 100 three year old red and black pines I want to further develop in their own colanders to increase trunk size and develop the nebari. I was told recently that turface is a bad choice for soil medium and I can’t afford to buy several more bags of clay king. So I get to my question,
WHAT IS A GOOD SOIL MEDIUM ALTERNATIVE FOR A HUNDRED SMALL PINES ( OR ANY DEVELOPING BONSAI ), THAT IS AFFORDABLE IN THAT QUANTITY?
I appreciate any and all help on where I can get this, and prices of these products?
Also I have been searching the web everywhere for the 6-8" cheap plastic colanders to buy in a bulk 50-100 pack, and the cheapest I found was around $2 each! Anyone have a link to where I can get them for under or around a dollar?
Thank you so munch!
