Frequently Asked Questions

What pest or disease commonly affects Thymus citriodorus (lemon thyme), and how can I fix it?

Lemon thyme (Thymus citriodorus) is prone to fungal issues like root rot when soil stays wet, especially in cool, humid weather. Improve drainage immediately by letting the top 1–2 cm of soil dry between waterings and thinning crowded plants for airflow; remove any blackened, mushy roots if you see wilting. If you notice gray, fuzzy growth on stems/leaves, cut back affected tips and keep the foliage dry by watering at the soil line.

How often should I water lemon thyme during its main growing phase?

During active growth (around the first 6–8 weeks after establishment), water deeply only when the top 1–2 cm of soil feels dry to the touch. Aim for a light, thorough soak then complete drainage, rather than frequent shallow watering; this herb performs best when the root zone alternates between moist and dry. Reduce watering as the plant matures and in cooler months, because lemon thyme is drought-tolerant but not wet-soil tolerant.

How do I tell when lemon thyme is ready to harvest?

You can start harvesting at about 60 days when new, fragrant growth is established and stems have enough leaf mass to pinch without stripping the plant bare. Harvest in the morning for the strongest lemon scent, taking small sprigs and leaving at least several sets of leaves on each stem so it can regrow. For best quality, avoid heavy harvesting during extreme heat or right after the plant has been stressed by drought or overwatering.
