Plant lamium in spring or early fall while soil is cool and roots can settle. Match species first: a silver maculatum carpet, a yellow-archangel runner, or an orvala clump. Set the crown at soil level. Keep the first weeks evenly moist. Year-round site and shear stay on How To Grow Lamium.
When to plant lamium
| Factor | Recommended | Avoid |
|---|---|---|
| Window | Spring as growth starts, or early fall | Peak heat with a dry, packed bed |
| Site | Part shade, moist well-drained soil, already decided | Planting first and choosing light later |
| Stock | Nursery pots or rooted divisions with a live crown | A leafless, rotting center shoved into wet clay |
North Carolina Extension: starter plants for a groundcover may sit about 6–10 inches apart for quick cover. Maculatum types such as White Nancy fill that spacing. Hermann’s Pride still wants shade, but plan an edge you can reach. Album is a clump — space it as a perennial, not as a 6-inch carpet grid.
Set the crown and space the mat
- Water the nursery pot the day before so the ball holds.
- Dig a hole no deeper than the pot. The crown sits at soil level, not buried.
- Loosen circling roots. Set the plant. Backfill with the same soil amended if it is packed clay, so water can leave.
- Space maculatum about 6–12 inches for a mat. Give galeobdolon more edge room. Space orvala as individual clumps.
- Water to settle. Mulch the soil, not the stems.
Contain runners at plant-out
- Know the class on Types Of Lamium before you mass-plant.
- Keep yellow archangel off an unmanaged wood line. Prefer Hermann’s Pride over the species if you want the look.
- Leave a path or mow strip you can cut. Maculatum roots as it trails; trim the edge in the growing season.
- Do not plant a rare dwarf perennial on that same edge unless you will edit weekly.
Beacon Silver and other silver carpets are still edit-and-cut plants, not a set-and-forget lawn substitute. Partners that share the shade sit on Lamium Companion Plants.
First weeks after planting
- Keep the soil evenly moist while roots take. Do not leave a saucer of standing water at the crown.
- Watch for slugs on new leaves. Pick them; do not drown the crown to “help.”
- If summer heat hits a spring planting, a light shear of scorched tips is fine. Full site-and-shear rules stay on How To Grow Lamium.
- Pull any all-green sport on a silver cultivar as soon as you see it.
FAQ
When should I plant lamium?
Spring as growth starts, or early fall while soil is still warm enough for roots.
How far apart do I plant spotted dead nettle?
About 6–12 inches for a carpet. Orvala clumps need perennial spacing, not a tight grid.
How deep do I plant?
Crown at soil level. Burying the crown in wet soil invites rot.
Can I plant in summer?
Only with shade and steady water. Cool soil is kinder.
Do I need a barrier for maculatum?
Usually an edge you can cut is enough. Yellow archangel species is the one to keep off a wood line.
Can I plant divisions?
Yes. Keep a rooted piece with a live crown. Replant at once at the same depth.
Where is watering after they take?

Is this the full care guide?
No. This is plant-out. Year-round care lives on How To Grow Lamium.
