About Walker's Low Catmint

Nepeta × faassenii 'Walker's Low' · also called Walker's Low Catmint, Faassen's Catmint · flowering

Walker's Low Catmint is an RHS Award of Garden Merit winner prized for its long season of lavender-blue flower spikes and aromatic grey-green foliage. A tough, drought-tolerant perennial, it billows attractively at border edges. Cut back hard after the first summer flush to trigger prolific rebloom through autumn.

Ideal humidity: 30–60%

Watch for — Powdery mildew: White fungal coating occurs in humid, crowded conditions. Space plants at least 60 cm apart, improve airflow, and avoid overhead watering. Rarely severe enough to require fungicide.

The watering schedule, season by season

Walker's Low Catmint 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 walker's low catmint is every 7–14 days 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 every 7–14 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.

Highly drought-tolerant after establishment. Water deeply but infrequently; soggy soil leads to root and crown rot. New plantings need consistent moisture for the first season.

How to tell walker's low catmint needs water

A calendar is the worst way to water walker's low catmint. 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 walker's low catmint for a day is almost always safer than over-watering it.

Overwatering vs underwatering walker's low catmint

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

Water quality notes

Tap water is generally fine for walker's low catmint 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 walker's low catmint, 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 walker's low catmint.
