About Pink Pewter Dead Nettle
Lamium maculatum 'Pink Pewter' · also called Pink Pewter Dead Nettle, Pink Pewter Spotted Dead Nettle · flowering
A refined, clump-forming ground cover with small, ruffled silver-grey leaves edged in a narrow green margin and soft salmon-pink flowers in late spring and early summer. Among the most ornamental Lamium cultivars, valued for its gentle colour combination. Performs best in cool, shaded positions with moisture-retentive soil.
Preferred mix: Humus-rich, moisture-retentive, well-drained loam
Watch for — Powdery mildew in dry spells: White powdery coating on leaves appears when roots dry out while air remains humid. Maintain consistent soil moisture and good spacing. Shear back affected growth.
Why pink pewter dead nettle needs this mix
Pink Pewter Dead Nettle hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Pink Pewter Dead Nettle comes from damp, shaded forest floors and has fine roots that scorch and brown the moment the rootball dries — the mix has to hold a steady reserve.
- Coir and compost give that reserve, while perlite keeps enough air that the constantly-moist mix does not turn anaerobic.
- Even moisture also keeps its thin leaves from crisping at the edges, which is this plant’s most visible stress signal.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons pink pewter dead nettle struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A free-draining, gritty mix dries too fast for pink pewter dead nettle — you get crispy brown edges and frond or leaf drop within days of one missed watering.
- A pure, airless peat mix swings the other way: it holds water but suffocates the fine roots and rots the crown.
- Letting the mix dry to the point it shrinks from the pot is very hard to re-wet evenly and stresses the plant badly.
Using a sharp, fast-draining "houseplant" or cactus-leaning mix that lets pink pewter dead nettle dry out. It needs a moisture-retentive but still airy blend.
pH — does it matter for pink pewter dead nettle?
Pink Pewter Dead Nettle prefers a slightly acidic mix (around pH 5.5-6.5); a peat-free compost-and-coir blend sits there naturally, so routine pH testing is unnecessary.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.

Drainage and the pot
Use a pot with a drainage hole but a less-porous material (plastic or glazed) so it does not dry too fast. Bottom-watering keeps the mix evenly moist without sogging the crown.
