Diagnosing Center Die-Back in Creeping Juniper

Creeping juniper with 12-inch brown centers in 4-foot spread indicates: physical damage (foot traffic), clogged drip emitter, disease (Phomopsis, Kabatina blight), or natural aging. Junipers develop dead zones when interior light is blocked by dense outer growth.

Investigation: check irrigation coverage, inspect for pests (spider mites, bagworms), test soil drainage. Prune dead centers to healthy wood—this stimulates lateral bud break. Improve air circulation with selective thinning.

If irrigation is adequate and no pests/disease found, it may be natural senescence. Replace with younger plants or different groundcover (Creeping Phlox, Sedum, Thyme) for the site conditions.

Junipers are tough but not immortal—15-20 year lifespan in landscape settings is common.
