Q.blue rug juniper disease
I have slight browning on the lower half of the branches.
?how or what to treat with.
I have since cleared the mulch from around the base.
I planted early this year–they were very small.
They are in full sun and on a slope so well drained.
Maybe I watered too much? or not enough?
Difficult to determine the exact cause from this image.
The link below can help you pinpoint the issue.
Start with watering.
In the first year it's important to water regularly. Aim for once a week and deep watering.
Do not overwater.
Check the soil ph, they prefer slightly acidic soil. Ph should be in the 4.5 to 8.5 range.
