Common questions
How much water does thyme need?
Thyme has middle-of-the-road water needs. Aim to keep soil moisture around 15–35%, letting the top inch dry slightly between waterings rather than staying soggy.
Can I grow thyme in a raised bed or container?
Thyme is a perennial that stays put for years, so give it a permanent in-ground spot or a large, deep container it can live in long-term.
Does thyme come back every year?
Yes — thyme is a perennial. Plant it once and it comes back each year, so pick a spot it can keep for several seasons.
