I will suggest that many gardening and lifestyle show are about seeling products rather than giving practical advice.
While there are people who keep their gardens to a very high standard and enjoy gardening there are many people who wish to do other things with their life.
How much enjoyment you get from gardening is a very personal thing.
It can be quite surprising how labour intensive a garden can be.
Top golf courses can employ in the order of 36 grounds people so each hole has the equivalent of 2 people working full time looking after it.
These people have all the correct equipment and training.
At the elite level a golf green can be mowed more than once a day.
The bowling green (an area about 30x40 meters) ant the sport’s club where I play petanque has a green keeping bill in the order of $10,000 per year to maintain.
