Troubleshooting
Coconut Thyme problems — and how to fix them
Coconut Thyme (Thymus praecox 'Coccineus') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Centre dieback
Older mats brown and thin in the middle from poor airflow or damp. Shear after flowering and divide every few years to rejuvenate.
Root rot
Wet, heavy soil causes blackening and collapse. Improve drainage with grit and avoid overwatering, especially in winter.
Leggy, sparse growth
Too little sun or over-feeding makes stems stretch and flower poorly. Site in full sun and keep soil lean.
Weed invasion
Gaps in the mat let weeds establish. Keep the carpet dense and hand-weed early before competitors take hold.
