Neglecting Soil pH and Fertility
Thyme thrives in slightly alkaline to neutral soils (pH 6.5–7.5). Planting in overly acidic ground can stunt growth and dull the herb’s flavor. I once battled spindly thyme in a freshly tilled veggie patch—an inexpensive soil test revealed a pH below 6. A sprinkle of lime brought those leaves back to life!
Because thyme isn’t invasive, it relies on you for a hospitable medium. Amending with garden lime or crushed oyster shell and adding just a touch of compost ensures balanced nutrients without the lush excess that invites fungal issues.
