Thyme - Key Growing Information

A clump of creeping thyme, grown from seed, will thrive in a sunny, well-drained location; this cultivar emits a delightful fragrance underfoot.

DAYS TO GERMINATION:

Allow 14–21 days at 65–70°F (18–21°C).

SOWING:

Transplants are recommended: start seed in flats 8–10 weeks before the last frost, sowing on the surface and covering with a thin layer of mix. Keep moist until it sprouts, then move seedlings into their own containers at 4 true leaves. Plant out after the last spring frost, 6–8" apart in rows 12–18" apart, and pinch the tips of upright types for bushier plants.

LIGHT PREFERENCE:

Full sun to part shade; in very hot climates, thyme needs some shade to thrive.

SOIL REQUIREMENTS:

Does best in light, dry soil with good drainage.

PLANT HEIGHT:

Varies.

PLANT SPACING:

Space plants 6–8" apart.

HARDINESS ZONES:

Varies.

HARVEST:

In the first year, cut only a few stems so plants can overwinter. From then on, harvest just as the flowers start to open, cutting back to 4–5" above the ground.
Note: Plants turn woody and should be divided or replaced after 3–4 years.

SCIENTIFIC NAME:

Thymus spp.
