I have a small raised garden at the back of my house. The wood border is 3 planks high. I want to lower half of this raised garden so that my older dog doesn't have to jump up.
This would involve cutting 2 of the border planks and then removing them and the dirt behind them.
The planks were set in a long time ago and are too heavy to lift.
How should I cut those planks? Should I use a chainsaw and do my best to avoid cutting the last plank?
The picture is what we currently have and I have draw what I am trying to achieve.
I'm new to this, don't have any tools other than a shovel, but am happy to buy some. Just not all the power tools as I don't plan on doing a lot of other work myself.
