For branches you can tie them up in 1m bundles and leave them out with the brown bin in North Ayrshire. No need to do anything with them although if you have a lot it might be worth spreading it out over a few collections. Go down to the [garden waste section](https://www.north-ayrshire.gov.uk/bins-litter-and-recycling/bins/bins-mainland-cumbrae.aspx#brown)
