Spring Spider Mites

Landscape Pest Alert:

I have seen a lot of mite damage on conifers in the past week. I’ve also seen a lot of alerts about them this month from various sources. The Spruce spider mite & the Southern Red spider mite are the most common cool season species & they are now very active after their winter inactive period.

Remember that conifers such as junipers, cedars, pines, spruce, etc. need full sun. These trees also need plenty of moisture, well drained soils, fertilizer and mulch to help plants resist mite pests year-round.

If you suspect that you have mites on your conifer, take a branch and tap in onto a sheet of white paper. Smear the paper with your finger. If you see red streaks appear, then you likely have mites.
