How about the unwanted seed that life planted in our garden, which we couldn't control until it grow before we can think of how to handle and control the unwanted germination or should I use the word 'plant'.
When we bought this house about five years ago, the garden was an absolute mess. We did a bit of what we could to clean it up, but we focused on renovating the house itself. The garden had to wait. However, I continually did something, even small things to improve it, and this year with the time and a lot of effort, I did a large amount and it looks pretty good. Sometimes, we "inherit" a pretty poor quality soil and garden, but with nurture, it can change. It isn't a fast process though.
We seem to want quick fixes, but filling a garden with plastic plants, doesn't make it a nice garden :)
