Brown tips on rose leaves

Asked June 17, 2019, 5:34 PM EDT

I live in Utah. We've had excessive rains for months. Some plants have brown tips on the leaves. I use systemic treatments every 6 weeks. What do you think is causing the browning?

This is a difficult question to answer remotely. Excessive fertilization, salt accumulation in the soil or an infection could be the cause. I suggest seeking advice from your local extension office. Alternatively, you could send me a few pictures of the plant and site and I'll do my best.
