Gardening trends come and go but do tend to hang around much longer than, say, designs in the fashion world. Think of tired trends like artificial grass and plastic topiary balls, which have experienced a gradual falling out of favor but now look decidedly stale.
These are two very obvious examples of outmoded ideas – fake is never good, right? But sometimes things aren't quite so clear cut, especially as tastes and ecological awareness have evolved so much in the last 10 years. The trends that no longer cut it can be far more subtle, and it might be surprising when you find out they have positive associations too, such as improving air quality or attracting wildlife.
