Oh yeah! Finally you managed to start working on the garden! 😍
Sure, there's a lot of more things to be taken care of, but you have taken the first step. I'm so looking forward to future updates. That's going to be an interesting journey that I'm more than happy to humble along with you.
As for the brambles: the only way to get rid of them is to mow them over and over again I suppose... those guys are quite strong and durable; that's probably going to give you some work to keep them in order.
