Hi,
Really like your Corokia and Kahikatea? (big single trunk).I will be curious to see how you go with branches on the NZ white pine.
I am learning how to create forests too, and I think NZ has some great species for them including Totara, Rata, and all Northofagus. But with your forest, I think you may need to re-arrange yours with closer gaps, so it looks like a group/stand not a plantation etc. Food for thought?
Are you planning to come up to Timaru in October or is it November for the SI show/demos? I am unsure if I will do a long day on Saturday or if work consumes me and I will give it a miss etc.
