I am very much new to all this and I had to re-pot a tree that was rather overdue and was growing in normal garden soil. I had to do some quite severe root thinning to get rid of all the clumps of clay and was very worried that the tree was not going to survive the "abuse". In the new medium I have had excellent root formation and the tree is doing well!!
I have just recently repotted a maple from German Peat into Bonsai General Soil Mix - its been 7 weeks and I can already see the difference in foliage.
Exceeded my expectation's, great quality and quick delivery. Ordered online from Durban on a Friday, and received it Monday. With this 2Lt bag, it should last several re-pottings when using a small (6" inch) container. It is a well balanced mix as described.
I have been using this soil for a while now, and my trees have flourished in this medium. Being in the western cape and experiencing both a wet winter and a dry summer with it, I can say that it provides excellent drainage, but what I like the most living in a hot dry cape in summer, is that it retains moisture very nicely too. Did I mention my trees have loved it? Excellent product
What can I say? Trees settled into new growing medium, will wait to see how they like it! (Should re-review end of the season.) Drains well, though.
