Watering at a glance

Base rhythm	Water when top 3-5 cm of soil is dry; keep evenly moist while establishing
Spring / summer	Spring and summer (active growth and bloom): keep evenly moist, watering when the top 2-3 cm is dry — typically when the soil tells you it is time.
Autumn	Autumn: ease back as flowering finishes and growth slows; let it dry a little more between waterings.
Winter	Winter / rest: water sparingly while it rests, then resume as new growth and buds appear.
Light	Medium indirect light (a couple of metres from a window)

About Geranium phaeum 'Samobor'

Geranium phaeum 'Samobor' · also called Samobor dusky geranium, Marbled-leaf cranesbill · flowering

Geranium phaeum 'Samobor' is a dusky cranesbill grown as much for its foliage as its flowers: each leaf bears a bold chocolate-maroon central band, making a striking mound even out of bloom. Deep maroon-purple flowers rise on slender stems in late spring and early summer. Holding an RHS Award of Garden Merit, it is an outstanding, shade-tolerant perennial for woodland edges and dry shade.

Ideal humidity: 40-70%

Watch for — Faded or scorched leaf markings: Hot, dry sun bleaches the chocolate banding and scorches leaves. Grow in shade with steady soil moisture to keep the markings bold.

The watering schedule, season by season

Geranium phaeum 'Samobor' flowers best on steady, even moisture — let it dry out hard and it drops buds; keep it soggy and the roots rot before it can bloom. The base rhythm for geranium phaeum 'samobor' is water when top 3-5 cm of soil is dry; keep evenly moist while establishing, 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 (active growth and bloom): keep evenly moist, watering when the top 2-3 cm is dry — typically when the soil tells you it is time.
Autumn (slowing down): Autumn: ease back as flowering finishes and growth slows; let it dry a little more between waterings.
Winter (rest / dormancy): Winter / rest: water sparingly while it rests, then resume as new growth and buds appear.

Prefers soil kept lightly moist for the best foliage. Established plants tolerate dry shade, but sustained drought brings early dormancy and crisped, faded leaves.

How to tell geranium phaeum 'samobor' needs water

A calendar is the worst way to water geranium phaeum 'samobor'. Check the plant and the soil instead — for this species, look for these signals in order:

The top 2-3 cm of soil is dry to the touch.
Leaves or flower stems lose turgor and start to droop.
Buds stall or the pot feels light.

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 geranium phaeum 'samobor' for a day is almost always safer than over-watering it.

Overwatering vs underwatering geranium phaeum 'samobor'

The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For geranium phaeum 'samobor' specifically:

Signs you are overwatering

Yellowing leaves, bud drop, and a heavy, constantly wet pot.
Mushy stems or crown rot at soil level.
Fungus gnats and a sour soil smell.

Signs you are underwatering

Wilting, bud and flower drop, and crispy leaf edges.
A faded, stressed look and a rootball that has pulled from the pot sides.

Erratic watering — bone dry then flooded — makes geranium phaeum 'samobor' drop its buds and flowers. Consistency through the budding period is what protects the display.

Water quality notes

Tap water is generally fine for geranium phaeum 'samobor' unless your water is very hard; rainwater is a safe default if leaf tips brown.

Seasonal and environmental adjusters

Every figure above shifts with the conditions in your home. For geranium phaeum 'samobor', the levers that matter most are:

A blooming plant in good light drinks faster than a resting one — shorten the interval during flowering.
Brighter, warmer spots dry the pot faster; check before watering rather than fixing a date.
Empty the saucer after every water so the roots are never sitting in run-off.

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 geranium phaeum 'samobor'.
