With the dry of the cold season and the coming hot weather until the rains come in May young trees suffer water stress.
A good 10 cm or more thickness of a mulch around trees helps conserve water in the soil and reduce the need for watering. Wikipedia has a helpful article on mulch.
This picture is of volunteer Mark carrying loads of chipped leaves and sticks at our regular Thursday morning working bee at the Railway Park Chiang Mai. We will need to keep watering young trees in the coming months and more volunteers are welcome to come along. We like to begin work around 7 a.m. to beat the midday heat.
