I want to make some of my garden maintence free.

What size gravel should I use 10mm or 20mm ?

I have heard that the 10mm is particually prone to letting weeds grow

20mm, mixed with cement, sand and water. It's the only way you will make gravel
maintenance free.



Dunno. We have gravel outside well compacted, and it does settle so we
need to chuck a bit more on from time to time around 10 year
intervals;!..
