Agronomic Services — Fraser Fir Tissue Sampling, slide 2 of 5
Select most recently mature shoots.
On well-established trees, collect needles
from the upper half of the tree but not from the top whorl or leader. Collect mature lateral shoots from the current season's growth. For routine analysis, choose healthy shoots undamaged by disease, insects, or environmental stress.
