Government’s one million tree-planting project is being hampered by a lack of irrigation by delinquent planters who are failing to properly maintain the trees.Coordinator of the National Tree Planting programme Dewyn Phillips made this disclosure following an award ceremony at Walkers Institute for Regeneration Research Education and Design Inc. in Walkers, St Andrew on Monday.Phillips said they were concerned about the high mortality rate in some communities. The main issue with the upkeep of the trees has been irrigation.Phillips declined to identify the communities where the problem existed.“You would recognise in certain areas you will see some trees drying . . . We’ve encountered two communities that requested trees early this year and I’m afraid to say there is a very high mortality rate.”
