Our garden is about 80 feet long, so not huge, but hasn't been looked after for about 10 years. The previous occupants let it go, and we have no idea about gardening so have just been cutting the lawn and trimming back the odd bramble that's sticking out too much. I don't think that there are many decent plants - it's just mainly brambles, weeds, and ivy everywhere in the beds.
Now that I'm starting to get a bit of time back, I'd like to rescue it and start again but I don't have a clue where to start.
Should I first strip everything back completely and then start with a blank canvas and put in new plants? Or do it area by area? It's going to take forever 
Any book/website recommendations for complete beginners on how to start a garden? Thanks!
