Watering at a glance

Base rhythm	Every 2-3 weeks in summer (active growth); none from mid-autumn to late spring during rest
Spring / summer	Spring and summer: a deep soak roughly every 2-3 weeks, but only once the mix is bone dry to the bottom of the pot. Tip the pot — if it still has any weight, wait.
Autumn	Autumn: stretch the gap and water perhaps half as often as in summer as growth winds down and light fades.
Winter	Winter: keep almost completely dry — once every 6-8 weeks at most, or not at all in a cool room. A cold, wet cactus rots within days.
Light	Direct sun (at least 4-6 hours)

About Dorothy's Living Stone

Lithops dorotheae · also called Dorothy's Pebble Plant, Living Stone · houseplant

Lithops dorotheae is one of the most prized living stones from Northern Cape, South Africa, featuring pale yellow to cream leaf pairs with a beautifully detailed network of darker lines on the windowed surface. It produces yellow flowers in late summer. Strict adherence to its annual dry-rest cycle is essential. Lithops are listed as non-toxic to pets by the ASPCA.

Ideal humidity: 15-35%

Watch for — Rot during rest: Even small amounts of water during the autumn-spring rest destroy the plant from the inside. The only treatment is prevention: strict dry rest.

The watering schedule, season by season

Dorothy's Living Stone is a desert plant — it would rather miss a month than sit in damp soil for a day. The base rhythm for dorothy's living stone is every 2-3 weeks in summer (active growth); none from mid-autumn to late spring during rest, 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: a deep soak roughly every 2-3 weeks, but only once the mix is bone dry to the bottom of the pot. Tip the pot — if it still has any weight, wait.
Autumn (slowing down): Autumn: stretch the gap and water perhaps half as often as in summer as growth winds down and light fades.
Winter (rest / dormancy): Winter: keep almost completely dry — once every 6-8 weeks at most, or not at all in a cool room. A cold, wet cactus rots within days.

Water only when the old leaf pair has visibly begun to shrivel, signalling active growth. Maintain a strict dry period from autumn through to late spring while new leaves emerge. Even a single watering during rest can cause irreversible rot.

How to tell dorothy's living stone needs water

A calendar is the worst way to water dorothy's living stone. Check the plant and the soil instead — for this species, look for these signals in order:

The pot feels feather-light when you lift it.
The mix is dry all the way to the drainage hole, not just on top.
Ribs or pads look slightly shrunken or wrinkled rather than plump.

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 dorothy's living stone for a day is almost always safer than over-watering it.

Overwatering vs underwatering dorothy's living stone

The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For dorothy's living stone specifically:

Signs you are overwatering

Soft, mushy, translucent patches at the base — advanced root or stem rot.
A swollen, almost bloated look followed by collapse.
Black or brown discolouration creeping up from soil level.

Signs you are underwatering

Mild puckering or a slightly shrivelled look (this one is harmless — just water).
Growth simply stops; colour can dull.

Watering on a calendar in winter is the single fastest way to kill dorothy's living stone. Cold soggy soil and a dormant root system equals root rot.

Water quality notes

Tap water is fine for dorothy's living stone. The danger is never the water type — it is the volume and the timing.

Seasonal and environmental adjusters

Every figure above shifts with the conditions in your home. For dorothy's living stone, the levers that matter most are:

Gritty, fast-draining cactus mix is non-negotiable — it changes everything about how fast the pot dries.
A terracotta pot wicks moisture out and is far safer than glazed or plastic for a desert plant.
In the brightest sun the pot dries faster, so a soak goes further — but still check before pouring.

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 dorothy's living stone.
