Another Cotoneaster Air Layer

A few years ago, at one of the Bonsai Europa events I purchased this material from a Spanish trader. It was a field grown cotoneaster with a very thick trunk. A trunk would take decades to become this thick in the Scottish climate; I can only assume that they grow much quicker in the warm Spanish climate.The first 2 pictures show how it looked when I acquired it. They were clearly developed with air layering in mind.

the first thing I had to do was to remove the moisture retaining organic soil and replace it with a more free draining mix of akadama and kiryudama.The next 3 pictures illustrate that process.

I let it grow throughout 2018 to allow it time to get established in the new pot and in 2019 I prepareed to air layer the top off the tree.

I separated the air layer in 2020 but I wasnt entirely happy with the root development on the upper part. It was a bit one sided so I planted it quite deep in the new pot and left  and gave it 2 growing seasons before I looked at the roots again. In 2 seasons it had filled this pot with a strong healthy root system.

Both trees were repotted this year and while the branch development still has some way to go their future potential as nice bonsai is now apparent.

  1. Wow! Nice find! I have trimmed my cotoneaster 3 or 4 times already this year, so plenty of growth to build from.
