Watering at a glance

Base rhythm	When the top 3-4 cm of soil is dry, roughly every 7-12 days
Spring / summer	Spring and summer: water deeply but only when the top few centimetres are properly dry — roughly weekly in the ground, more often only for pots in heat.
Autumn	Autumn: cut right back as growth slows; established plants need very little.
Winter	Winter: keep nearly dry, especially in pots — wet winter soil is the classic killer of rosemary, lavender and thyme.
Light	Direct sun (at least 4-6 hours)

About Pelargonium graveolens 'Lady Plymouth'

Pelargonium graveolens 'Lady Plymouth' · also called Lady Plymouth geranium, Variegated rose-scented geranium · herb

'Lady Plymouth' is a classic variegated rose geranium with deeply cut grey-green leaves boldly margined in creamy white. It holds an RHS Award of Garden Merit, releases a strong sweet rose scent and bears small mauve-pink flowers. A tender South African perennial, it wants full sun, sharply drained gritty soil and protection from frost.

Ideal humidity: 30-50%

Watch for — Overwatering rot: Mushy stem bases and yellowing leaves follow waterlogging. Use gritty mix, water only when dry and never leave standing water.

The watering schedule, season by season

Pelargonium graveolens 'Lady Plymouth' is a lean, sun-loving Mediterranean herb — it grows best kept on the dry side and rots fast if it is watered like a leafy plant. The base rhythm for pelargonium graveolens 'lady plymouth' is when the top 3-4 cm of soil is dry, roughly every 7-12 days, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.

Spring & summer (active growth): Spring and summer: water deeply but only when the top few centimetres are properly dry — roughly weekly in the ground, more often only for pots in heat.
Autumn (slowing down): Autumn: cut right back as growth slows; established plants need very little.
Winter (rest / dormancy): Winter: keep nearly dry, especially in pots — wet winter soil is the classic killer of rosemary, lavender and thyme.

Water thoroughly, then let the compost approach dryness. The variegated foliage is forgiving of short drought but quick to rot in soggy soil; cut back hard in winter.

How to tell pelargonium graveolens 'lady plymouth' needs water

A calendar is the worst way to water pelargonium graveolens 'lady plymouth'. Check the plant and the soil instead — for this species, look for these signals in order:

The top 3-4 cm of soil is fully dry and the pot is light.
Foliage looks slightly dull or limp in heat (recovers fast once watered).
For potted plants, the rootball has shrunk slightly from the sides.

The most reliable single check is the first one on that list. When two signals agree, water; when they disagree, wait a day and look again — under-watering pelargonium graveolens 'lady plymouth' for a day is almost always safer than over-watering it.

Overwatering vs underwatering pelargonium graveolens 'lady plymouth'

The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For pelargonium graveolens 'lady plymouth' specifically:

Signs you are overwatering

Yellowing, blackening or dropping lower foliage; a sour, wet pot.
Soft, rotting stems at the base — often fatal in rosemary and lavender.
Sudden collapse despite "looking thirsty" (it was actually drowning).

Signs you are underwatering

Crisp, brittle, browning foliage and stalled growth (less common — these herbs are drought-hardy).
For young, unestablished plants only, wilting in extreme heat.

Overwatering and rich wet soil are what kill pelargonium graveolens 'lady plymouth', not drought. It evolved on dry, stony hillsides — err on the side of too little.

Water quality notes

Tap water is fine for pelargonium graveolens 'lady plymouth'; drainage and restraint matter, not water type.

Seasonal and environmental adjusters

Every figure above shifts with the conditions in your home. For pelargonium graveolens 'lady plymouth', the levers that matter most are:

Sharp drainage is everything — grit in the mix and a terracotta pot keep it alive.
Established plants in the ground are highly drought-tolerant and rarely need watering at all.
Pots dry faster and need more attention than open ground, but still let them dry between waterings.

Pot choice is part of this too — work out the right size with the pot size calculator, since a pot that is too big stays wet long enough to rot the roots of pelargonium graveolens 'lady plymouth'.
