How often to water succulents — indoor + outdoor guide

Most succulent deaths come from one mistake: watering on a schedule instead of by need. Succulents evolved in arid soil where rain is irregular; they're built for the dry-soak-dry cycle. This guide is the watering protocol that works for indoor and outdoor succulents in US and UK conditions.

Set the right reminder: Add your succulent to Growli and the app sets a watering interval calibrated to your light, season, and pot — adjusting automatically as conditions change.


The wrinkle test (better than a schedule)

Look at the lower leaves. When they go from plump and firm to slightly wrinkled and soft, the plant has used its water reserves and is ready for the next watering. Wrinkling is normal and healthy; mushy translucent leaves are not (that's overwatering — see why is my succulent dying).

The wrinkle test means you stop watering by calendar. Instead, walk past your succulents weekly and water only the ones that look wrinkled.

Frequency by setting

SettingSummerWinterNotes
Indoor bright windowEvery 10-14 daysEvery 3-4 weeksStandard
Indoor low lightEvery 14-21 daysEvery 4-6 weeksPhotosynthesis is slow — water needs are lower
Outdoor full sun (US zones 8-11, UK summer)Every 5-7 daysn/a (bring indoors below 5°C/40°F)Hot, dry conditions speed up water use
Outdoor partial shadeEvery 10-14 daysn/aSame as indoor bright
Terrarium (no drainage)Sparingly — half a shot glass once a monthHalf a shot glass every 6 weeksHigh risk of rot; consider a different pot

These are starting points. Adjust based on the wrinkle test.

The right way to water (soak and drain)

  1. Water until water runs from the drainage hole — not a light surface mist.
  2. Let drain completely (5 minutes in a sink or tray).
  3. Empty the saucer; never leave standing water.
  4. Wait until the soil is bone dry AND the leaves wrinkle.

Light frequent watering creates shallow roots and the slow rot of "kept moist" succulents. Deep infrequent watering creates strong drought-tolerant plants.

Indoor vs outdoor

Indoor succulents typically need LESS water than outdoor ones because:

A succulent on a hot south-facing windowsill in summer might need water every 7-10 days. The same plant in a cooler corner of the same house might go 3 weeks between waterings.

Soil and pot — the 80/20

Watering frequency only works if drainage works. Two non-negotiables:

  1. Pot with a drainage hole. Decorative pots without drainage are succulent killers. Use a plain nursery pot inside the decorative pot if you must.
  2. Gritty mineral soil. Bagged "cactus soil" is usually still too peat-heavy. Mix 50% bagged cactus mix + 50% perlite or pumice for indoor succulents. Outdoor in the ground, amend planting holes with sand/grit.

With proper soil and a draining pot, you can't really overwater on a 10-day schedule. With poor drainage, even a 3-week schedule will rot the roots.

Winter watering — the most-killed-by season

Most succulent deaths happen between November and March. Why: people keep watering on their summer schedule, but the plant's water use drops by 50-70% in low winter light. Cut your watering frequency in HALF in winter, minimum.

If you have a particularly dim indoor spot, some succulents (Lithops, Conophytum) want NO water from December through March. Research your specific species.

Frequently asked questions

How often do you water succulents indoors?

Every 10-14 days in summer, every 3-4 weeks in winter — but only when the soil is bone dry and the lower leaves start to wrinkle. Skip the calendar; use the wrinkle test. Most indoor succulents are killed by frequent light watering rather than infrequent deep watering.

How often to water a succulent?

Most succulents in average indoor conditions need water once every 10-14 days in spring and summer, once every 3-4 weeks in fall and winter. Always check that the soil is completely dry first. Outdoor succulents in hot full sun need more frequent watering (every 5-7 days).

How often to water succulent plants in pots?

Container succulents need the same dry-then-soak cycle as in-ground succulents, but small containers dry out faster than large ones. A 4-inch pot might need watering every 7-10 days; a 12-inch pot might go 3-4 weeks. Use pot size + the wrinkle test together to time it.

How often do you need to water succulents?

Less than you think. The most common succulent-killing mistake is weekly light watering. They evolved in soils that get drenched then dry out completely for 1-3 weeks. Replicate that pattern: water deeply, drain fully, wait until the soil is dry AND the lower leaves wrinkle.

How often to water succulents indoors in winter?

Every 3-4 weeks at most, and some species (Lithops, Conophytum) want no water from December through March. Indoor winter light is dim, room temperatures are cool, and water use drops by 50-70% compared to summer. Cutting back is the single most important winter adjustment.

How can I tell when my succulent needs water?

The wrinkle test: look at the lower leaves. When they go from plump and firm to slightly wrinkled and soft, the plant has used its water reserves. Wrinkling is healthy and normal — it means the plant is ready for the next watering. Translucent or mushy leaves mean overwatering, not thirst.

Can I bottom-water succulents?

Yes — and it's often gentler than top watering for small succulents. Set the pot in a saucer of water for 20 minutes, let the soil draw up moisture, then remove and drain. Don't leave the pot sitting in water beyond that. Bottom watering encourages roots to grow downward, which is healthy.

How does Growli know how often to water my succulents?

Add your succulent to Growli with a photo. Growli identifies the species, estimates your light from the photo, and sets a watering interval. Photograph the lower leaves periodically — Growli detects wrinkling vs healthy plump leaves and adjusts the next reminder up or down accordingly.
