One of the best advantage of Tibolar-RS (NPK 4-6-2) is, that it’s applicable in repotting bonsai, verns, to be brief, every plant/tree.
First ‘victim/guinea pig’ was a Trident maple. In april 2013 taken from open ground and almost every root was trimmed. First layer of akadama placed in the pot. On this layer I put the powdered Tibolar-RS (NPK 4-6-2) untill it was totally covered. Than the second layer, where I replanted the maple. Wired it firmly in the pot and filled the pot up with akadama.
In October 2013 I took the tree out of the pot with this result. Tree was totally potbound rooted.
So in 5 months I had a result what you normally get in two years (two growing seasons)! Because Tibolar-RS (NPK 4-6-2) is so mild it wont damage the roots. It stimulates rooting and growth.

Two months later..
Fern roots are very vulnerable. And this is what happens with ferns, when planted on Tibolar-RS (NPK 4-6-2). For this small fern, I took 5 pellets (+/-3 grams) and planted it ON the pellets.
