About Pau's Germander
Teucrium carolipaui · also called Pau's Germander, Bitter Germander · flowering
Teucrium carolipaui is a small, aromatic subshrub endemic to southeastern Spain (Murcia and Alicante provinces), where it grows in the driest scrubland, rocky ravines, and stony steppes on calcareous, gypseous, or marl-saline soils. It is closely allied to other compact Iberian germanders and produces the typical two-lipped flowers of the genus in summer. Excellent drainage and full sun are the key requirements; it is well adapted to poor, alkaline substrates and summer drought. The plant is mildly toxic if ingested, consistent with the hepatotoxic diterpene chemistry documented across the Teucrium genus.
Ideal humidity: Low
The watering schedule, season by season
Pau's Germander 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 pau's germander is very infrequently; relies on natural rainfall once established, 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.
Adapted to some of the driest conditions in Spain; water sparingly during the establishment period only, and ensure drainage is perfect to prevent root rot in wetter climates.

How to tell pau's germander needs water
A calendar is the worst way to water pau's germander. 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 pau's germander for a day is almost always safer than over-watering it.
Overwatering vs underwatering pau's germander
The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For pau's germander 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 pau's germander drop its buds and flowers. Consistency through the budding period is what protects the display.
Water quality notes
Tap water is generally fine for pau's germander 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 pau's germander, 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 pau's germander.
