Base rhythm	Moderate in summer; very little in winter
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.

About Woolly Rock Jasmine

Androsace lanuginosa · also called Woolly Rock Jasmine, Lanuginose Androsace · flowering

Woolly Rock Jasmine is a trailing, silver-hairy alpine perennial from the Himalayas, forming long, lax stems covered in silky woolly rosettes. From midsummer into autumn it bears umbels of pale lavender-pink to deep rose flowers, making it one of the longer-flowering Androsace species. Ideal for dry walls, rock garden cascading positions, and raised troughs.

Ideal humidity: Low to moderate, 30–50% RH

Watch for — Powdery mildew: Mildew can affect foliage in hot, dry spells with poor air circulation, appearing as a white powdery coating. Improve ventilation, avoid evening watering, and treat with a fungicide if spreading. Good siting in an open position is the best preventative.

The watering schedule, season by season

Woolly Rock Jasmine 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 woolly rock jasmine is moderate in summer; very little in winter, 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.

More tolerant of summer moisture than high-alpine Androsace species, reflecting its Himalayan origin with monsoon influence. Water moderately during the growing and flowering season; allow periods of drying between applications. Reduce sharply in autumn and keep nearly dry in winter. Good drainage remains essential at all times.

How to tell woolly rock jasmine needs water

A calendar is the worst way to water woolly rock jasmine. 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 woolly rock jasmine for a day is almost always safer than over-watering it.

Overwatering vs underwatering woolly rock jasmine

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

Water quality notes

Tap water is generally fine for woolly rock jasmine 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 woolly rock jasmine, 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 woolly rock jasmine.
