Succulent Water Calculator
Succulent soak amounts and monthly water by pot count and size.
What it does
Succulents want rare deep drinks, not daily sips. A full soak followed by real dry time grows roots that sip steadily.
The tool above multiplies pots by size. Five medium pots need 20 oz per soak, or 80 oz across summer months and 20 oz in winter. The metric match is 600 ml per soak toward 2,400 ml summers.
Size sets the pour. Small pots near 2 oz, medium near 4 oz, large near 8 oz, each until water runs from the drain. Saucers emptied after keep crowns dry.
Seasons set the calendar. Weekly summer soaks suit bright growth, while monthly winter water suits sleepy plants in cool windows.
Soil dryness rules ties. Dry to the second knuckle means soak, damp means wait, whatever the calendar says.
How to use
- Pick imperial (oz) or metric (ml).
- Enter pot count.
- Pick size: medium suits many windows.
- Read session soak first.
- Read summer and winter months.
- Soak, drain, and let dry between.
Formula
- pots
- Pot count.
- size
- Small, medium, or large pots.
Sizes are small 2 oz or 60 ml, medium 4 oz or 120 ml, large 8 oz or 240 ml. Summer assumes weekly soaks, winter monthly.
Worked example
Example: 5 medium pots
Imperial defaults: 5 medium pots. These are also the default values, so the page opens on this answer.
- Pots: 5 medium.
- Each: 4 oz per soak.
- Session: 5 x 4 = 20 oz.
- Summer: 20 x 4 = 80 oz per month.
- Winter: 20 x 1 = 20 oz per month.
- Tool shows 20 oz per watering, 80 oz per summer month, 20 oz per winter month.
Reference table
| Collection | Session | Summer |
|---|---|---|
| 5 small | 10 oz | 40 oz |
| 5 medium | 20 oz | 80 oz |
| 5 large | 40 oz | 160 oz |
| 5 medium metric | 600 ml | 2,400 ml |
Limits
- Soak math only. Light and soil rule health.
- No hole pots need less water.
- Winter sleep varies by heat and light.
- Rot needs diagnosis, not schedules.
Common mistakes
- Sipping daily instead of soaking rarely.
- Leaving saucers full for days.
- Misting instead of watering roots.
- Wintering on a summer schedule.
- Potting in garden soil that stays wet.
Try it yourself
Quick checks. Answers sit tucked under each question.
10 small pots?
10 x 2 = 20 oz per soak. Summer is 20 x 4 = 80 oz. Winter is 20 oz.
3 large pots metric?
3 x 240 = 720 ml per soak. Summer is 720 x 4 = 2,880 ml.
Questions
Water per session?
Multiply pots by size ounces. Here 5 x 4 = 20 oz per soak.
How much per pot?
Small 2 oz (60 ml), medium 4 oz (120 ml), large 8 oz (240 ml) per soak.
How often?
Weekly soaks in summer, monthly in winter for most indoor pots. Soil dry to the second knuckle rules.
Soak or mist?
Soak until drains run, then empty the saucer. Mists wet leaves without wetting roots.
No drainage holes?
Yes. Pots with no holes need less and longer dry spells.
Does this treat rot?
No. Rot and pests need plant diagnosis.
