i've been noticing the tops of young redwood trees in my neighborhood turning brown?

Question

they eventually die. what is causing this? i'm concerned because i planted some redwoods last spring.

Answer 1

What you're probably witnessing is the result of the trees being exposed to a disease called; "Phytophthora ramorum".... also known as "Sudden Oak Death". This disease is transmitted very easily and has killed thousands of oak trees (as well as tanoaks) in the Northern California area. The good news is that redwoods might lose some of their foiliage (the browning you're seeing) but they seem to be able to survive after infection.

This disease was noticed on redwoods about 10 years ago and has also been found on Douglas Firs. Many of the researchers believe the disease won't kill any of the conifers since they seem to exhibit an natural resistance to the disease (other than some foliage loss). But the bigger issue is that the oak trees are being destroyed by this disease and will serve as fuel if/when subjected to forest fires. Since these dead oaks are found within forests of redwoods, they could intensify the fires and therefore destroy everything around them...including the redwoods.

My advice is to not remove your young trees but stay informed about any new developments by the University of California-Berkeley and Davis about ways to keeping your trees healthy.

Hope this answered your question. GOOD LUCK keeping your trees healthy!

status, sitting or laying contained in the air of secrecy of trees will enable the trees to bare to us their power, resilience, persistence and deliberatness. I have witnessed many a tree to absolutely defeat a bulldozer and maximum earth shifting machines, their roots boost for far further than maximum persons imagine, giving them the flexibility of the Earth, yet in a good wind they could bend to accomodate the replacing forces that still attempt to flow them. they tend to live longer than us ALL in words of obdurate existence and would instruct us the persistence of surviving hostile to repeated onslaughts. even although timber is softer than rock, a tree can, through the years, actually cut up even the biggest of boulders with its roots. trees have all this and so a lot extra to reveal us if we would only make an attempt to pay interest, watch, and study from them.
