Camden Council writes:
“After planting, trees have three seasons of young tree maintenance. This includes weeding, watering and adjustment or removal of stakes. Young trees are watered for the first three seasons after planting. Trees are watered from May to September every two weeks.Any water residents can add to the trees would be beneficial to helping the trees establish. To use the irrigation bag just pour water into the hole on the bag above the new `help water me’ sticker. The bag will slowly release the water into the soil over 3-6 hours.
