Is it worth or even beneficial to tidy up the garden?

“No Mow May” is worse than a winter tidy up because the flowers are still producing pollen and nectar and wildlife is flourishing, in winter plants are declining and wildlife is resting. To be safe, don’t do either .

 

When we moved into the flat with garden 10 years ago, I followed Alan Titchmarsh advises which all turned out to be wrong over the years.
I tidy up the gravel from the leaves in Autumn and I cut the Hardy Geraniums in December because it's not easy to do it when left until the new grow started to show up.
There is only one exception that I do all year round: I take out weeds.
