Don't put them on the village 'green' by the telephone box, or any other village open space. If you do you will be fly-tipping. Daventry District Council no longer collects trees from central points in villages.
Instead, leave your tree by the brown bin for pick-up with the next scheduled garden waste collection, which starts in Daventry District in w/b 18th January. Details for Cold Ashby are on the Daventry website.
You can also take them to the waste recycling centre at Brixworth..
Happy New Year
