- 1). Saturate the soil around a newly planted emerald cedar tree with water. This is known as "watering in," or basically filling in the dry or patchy spaces of the soil with water. Ensure that the ground immediately surrounding the tree is heavily saturated for at least one week.
- 2). Dig down with a small shovel about 3 inches deep. If the soil is dry at this depth, re-saturate the area with water for about 30 to 45 minutes. Check this area weekly during spring and summer months.
- 3). Water the emerald cedar tree once a week, for 30 to 45 minutes, during the first year after the tree has been planted. During extremely hot or dry weather, you may increase the watering time to twice weekly.
- 4). Check the tree frequently during its second year and, if needed, water it every two weeks, for 30 to 45 minutes. The second year may require no additional watering, aside from rainwater, as the roots will have pushed below the "drip line," or water table, and have access to a steady water supply.
