We were back on Stoke Newington Common, giving the young trees their weekly drink - very much needed after the temperatures we've had of late.

With the new Two-Team System in place, the group whipped round the common with their canisters and cart, keeping the little whips and saplings (and some slightly older trees too) alive for another week.

This weeks innovation - using a tree guard to aid the decanting of water from a large (heavy) cannister into smaller (lighter) cannisters.
