Spring & summer (active growth): Spring and summer (active growth and bloom): keep evenly moist, watering when the top 2-3 cm is dry — typically every 4-7 days.
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.

How to tell sanguisorba 'tanna' needs water

A calendar is the worst way to water sanguisorba 'tanna'. 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 sanguisorba 'tanna' for a day is almost always safer than over-watering it.

Overwatering vs underwatering sanguisorba 'tanna'

The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For sanguisorba 'tanna' 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 sanguisorba 'tanna' drop its buds and flowers. Consistency through the budding period is what protects the display.

Seasonal and environmental adjusters

Every figure above shifts with the conditions in your home. For sanguisorba 'tanna', 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 sanguisorba 'tanna'.
