And, yes I struggle with a number of different native trees like you do. It can be frustrating at times but I wouldn't have it any other way.
Great looking slash pine bonsai!
I would not mind some tips, I've got a slash pine "potensai"
I'm still trying to figure out how to prune it efficiently and how to give more strength to the lower branches while hindering the top growth.
I've just recently cut out the top candles that were starting to grow.
Are the Slash Pines you have field grown trees or collected from the wild? I would love a couple of these to add to my collection. Where do you get them? Dave Colorado Springs
