My Trees Are Browning!
Every fall Earth-Wise receives phone calls from customers concerned about the browning needles on their pine, spruce and fir trees. Not to worry, this is a normal process. Depending on species, location and overall health of the tree, conifers typically hold on to needles for 3 – 7 years. Older needles become less efficient at photosynthesis due to shading from new growth and excess wax buildup. Thus, these older needles are no longer productive for the tree and are shed in the fall.
