Where flooding has become more frequent, here's how gardeners can respond

This info is common stuff for people who know their stuff, granted may be useful for newbies.

Had a lovely big garden when I lived in the sticks, grew so many things, miss that a bit, but not a lot.

Extreme rainfall is more frequent now, atmospheric scientists say, as storms form in an atmosphere made warmer by climate change.

Or maybe rainfall is more frequent and heavier because of a massive volcanic eruption in Tonga last year which dumped 10% more water into the atmosphere than was already there. NASA claims that’s equivalent to 58,000 Olympic size swimming pools so obviously there’s going to be a bit more precipitation. Extra water vapour in the air will also warm the atmosphere.
