How to avoid run away trees
I'll be terracing a big area for the gardening over time.
The terrace structure or retaining wall, if you will, is going to be utilizing as much tree trash as possible (prunings and coppicing trash trees)
Which of these will not sprout easily?
As you experts might imagine, Poplar is the most readily accessible. The horizontal rod supports need not bend so they can be completely dead. Is it still risky to use poplar like this?
I guess there's a risk for any of these used horizontally.
Thanks for your time
