Creeping thyme is one of the prettiest, toughest ground covers you can plant. It spills over retaining walls, fills the gaps between pavers, and even works as a low-water lawn alternative. Here is exactly how I planted mine from seed, step by step, so yours gets the best possible start.

Quick answer: Scatter creeping thyme seed about an eighth of an inch deep, or right on top of loose soil, keep it consistently moist with a gentle shower setting once or twice a day, and be patient as it fills in. It is a low-growing, spreading ground cover that thrives in sun and poor soil.

Where to plant creeping thyme

Creeping thyme loves sun and does not mind lean soil. I planted mine along a retaining wall so it can trail and hang over the edge, but it is just as happy between stepping stones, along a walkway, or spreading across a slope. Give it a spot with good sun and it will reward you.

How to plant the seeds

The seeds are tiny, so they come in a little packet to keep you from losing them. They only need to be about an eighth of an inch deep, which is barely under the surface, so I simply scatter them right on top of my existing soil.

  • Pour a little seed into the palm of your hand
  • Spread it across the area, using your fingers to disperse the seeds evenly
  • Leave them sitting on top of the soil or barely press them in, no deep planting needed

Watering, the part that matters most

This is where most people go wrong. After spreading the seed, water it in with your hose on a gentle shower setting so you do not wash the tiny seeds away. Then keep the ground consistently damp. I water every single day on the shower setting, and sometimes twice a day when it gets warm, until the seedlings are established.

What to expect as it spreads

Be patient. Creeping thyme starts small and fills in over time into a dense, low mat of green that bursts into tiny flowers. Keep it watered through establishment, and once it takes hold it is wonderfully low maintenance and drought tolerant.

A hose with a gentle shower setting is the one thing you really need so you do not blast the seeds out of place. Here is the garden hose I used.

Frequently asked questions

How deep do you plant creeping thyme seeds?

Only about an eighth of an inch, barely under the surface. You can scatter the seeds right on top of loose soil and lightly water them in.

How often should I water creeping thyme seeds?

Keep the soil consistently moist while seeds germinate and establish, watering daily on a gentle shower setting, and twice a day in hot weather. Ease off once it is established, since mature creeping thyme is drought tolerant.

How long does creeping thyme take to spread?

It starts slow and fills in over a season or two into a dense mat. Consistent watering during establishment speeds it along.

Is creeping thyme a good lawn alternative?

Yes. It is low growing, handles light foot traffic, needs little water once established, and flowers, which makes it a popular low-maintenance lawn alternative and filler between pavers.
