Hi all! Just a quick question. As you can see from the photos some of the foliage on my dawn redwood is turning reddish brown. Could it be too much fertilizer? I hope that it’s not something worse. I fed it with an 18-4-10 slow release fert in teabags for about a month and a half, and then switched to a 12-10-11 slow release fert that’s urea free and supposedly more gentle and much longer lasting. But this leaf browning has been getting worse the past few weeks. So I took the fert bags off a few days ago. I water my redwood once a day or once every other day depending on the weather because I know they like wetter conditions and because he has well draining soil. What do you guys think is going on? Was I right to remove the fert teabags? I don’t think this could be caused by sun because I have him under a shade netting most of the time. Please share your insights, and thanks for your time.
