I am completely useless at gardening and intimidated by it (I got my first ever garden a few years ago, in my 40s). But I'm trying to get a bit more competent so would appreciate any kind, patient advice.
At the front, I have a small square gravelled garden, which constantly spills onto the path. What's the cheapest, easiest way for me to edge this? I'm hoping for something I can do with a hammer, rather than a concrete mixer... Do I have to be careful of the membrane under the gravel?
Huge thanks!
