I have a 40 yr old Brush Cherry which has never flowered since being in my care. I understand that this tree is an acid loving, tree, and potentially incorrect soil is one 0f the reasons it is not flowering (among others!!).
I am thinking of using Kanuma soil next time I repot this tree, but I have never used this substrate before.
My question is, should I use just 100% Kanuma soil, or should I use a mix?
If I should use a mix, which substrates are best and in what ratios? Eg pumice? Lava rock? Akadama?
Please bear in mind that I am a relative novice in bonsai care.
Thanks for any advice
