Water like a pro

A busy day as a colleague and I set out with to water trees planted last Autumn . The trees each have a water bag around their trunk and each bag needs 15 gallons of water. The water slowly trickles out and moistens the soil without any loss of water run off. This needs to be repeated each week if there is no significant rainfall. This happened through last summer and all the new tree planted in Autumn 2020 survived.
