Why are the tips of my needles on my Concolor Pine Tree turning a reddish brown?
Sometime mid-winter I noticed the tips of the needles turning a reddish brown.
While Concolor fir (not pine) is considered a drought tolerant conifer; this could be winter drying or dessication. If the browning is fairly uniform on the tree (such as on the south side.......) and needles have uniformly turned brown from the tip back, that would confirm winter drying. Adequate summer and fall watering, without overwatering, is important, along with avoiding any fertilization after the end of July. If new growth occurs this year, the tree should be fine; unless there is some other issue such as a root problem. Water correctly and don't fertilize the tree.
