Dawn Redwood Bonsai Pruning Advice- please help / what would you?
My Dawn Redwood Bonsai tree is starting to bud, and I was hoping to prune and reshape it before spring, or before the ideal period slips by. I have been searching for someone with experience in my area who shares my passion for bonsai and plants alike, whom I could sit with and learn from. The local bonsai society finally responded to my request to join a couple months ago, but then I never heard back with details as promised. Until then, I shall continue reading and researching the internet. If anyone lives near Northern Delaware, please contact me if you need a Bonsai Buddy!
To the issue, I purchased this Dawn Redwood last year from the internet, and it was labeled as 22 years old. I haven't touched it until a couple weeks ago, when I thought ready to repot and prune. I feel I did a fine job reducing the overdue, compact roots, and then I repotted with fresh soil -Al's Gritty Mix 1:1:1 (I love the stuff). Now I feel like time is running out, and with the buds popping, I need to cut most of the overgrown branches that throw it out of proportion, and which are not helping the taper of the trunk at all either. I have an idea of what I want to chop, which is almost everything to start from scratch. I guess I want the branches to be thinner at the top and thicker at the bottom. Also, more spread out branch placement with new growth on the bare side would be my ultimate goal, I suppose.
If anyone would be so kind to take a look at my photos taken today, March 11, 2014, and respond with the approach you would take for reshaping the tree, I could use the help. Or even if you have had one in the past, or have seen it done somewhere, or perhaps just have experience in the art of bonsai...anything would help. I have my professional concave cutters and knob cutters ready to go, but every time I sit to plan my approach, I fret that my inexperience will ruin what I want to accomplish in the distant or perhaps near future.
Thank you to all who have helped me in the past with providing knowledge, experience, and insightful debates on these forums, from which the lone bonsai enthusiast can learn from.
