5 Tips for How to Grow Thyme

HOW TO GROW THYME: 5 TIPS FOR GROWING THYME

1. Plant thyme at the right time

Space thyme plants about one foot apart. To plant thyme from transplant, choose sturdy well-branched plants with growth spilling over the pot. Avoid tall and gangly plants. Don’t buy transplants with brown leaves or dry spots. 

To plant thyme from seed, be patient. Thyme seeds may take several weeks to germinate. Sow seeds ¼ inch deep indoors about 6 weeks before the last frost date. 

Thyme can also be propagated by stem cuttings, root divisions, and layering.

2. Care for thyme correctly

Thyme grows best in warm, sunny areas. Don’t let thyme roots get soggy. Thyme tolerates dry conditions and poor soil, but will die if the soil is soggy and not well-draining. Thyme seems to thrive on neglect.

If thyme becomes wilted with yellow stems, it is probably suffering from root rot caused by overwatering or poor drainage. Remove and dispose of affected plants. Planting thyme in raised beds can help with this issue. 

Cut back thyme regularly throughout the growing season to discourage flowering and to encourage new growth. As the weather cools, allow thyme to go dormant and do not cut it back. Mulch well with compost to provide cold protection. 

Prune back dead thyme stems in spring. New growth should appear in late spring. Thyme can also be divided in late spring. Replace plants every few years for most flavor.
