Shimpaku Juniper needles browning, drying - help!

[csmileyk]

Hello All,

I have a few junipers in training. About a week ago, I noticed that some of them have parts of their foliage to be brown, some of the needles seem dry, almost crunchy, and drop off when touched. Here is some more information about them

1. Two weeks ago I applied two or three spoonfuls of 14-14-14 fertilizer
2. I live in Dublin, CA, we had a few days of 96+ deg F, and the plants were in full sun during the afternoon
3. It also gets extremely windy

So, I am not sure if it is fertilizer burns, or some pest. I did spray using BAYER ADVANCED 3-in-1 Insect, Disease and Mite Control, and moved the plants to a shady area of the yard.

Any thoughts on what is causing this?

Thanks for looking into this.

It looks like a chemical burn. Check for spider mites too, but that makes foliage pale gray for a while first before it dies.

Thanks Brian.

Anything I can do to reverse, protect the rest of the plant?

You won’t reverse dead Juniper foliage. Keep it out of direct afternoon sun for now, watch it for pests, and when it’s growing again, showing bright green and plump tips, you can carefully trim away the dead parts. Should be fine.

Mine looks worse but similar after dog pee.
