Planting depth affects quality

Research article 1, 2

Liners must be planted carefully in order to grow quality trees. Each step of the planting process must be done with precision. Position the point where the top-most root emerges from the trunk within the top inch or so of the soil or substrate surface. Planting deeper can cause problems in tree species that do not produce adventitious roots along the buried portion of the stem. Most tree species do not produce enough adventitious roots above the flare to develop a uniform root system.
