Commercial crop requirements
Growing Brussels Sprouts: climate, soil and water requirements
Brussels Sprouts has an optimum temperature range of 12–20°C within an absolute 7–25°C envelope.
Its profile calls for 450 mm of seasonal water and an optimum soil pH of 6–7.
How to read the figures
Profile figures come from the source cited at the foot of this page. Regional figures are representative reference values, not coordinate-level measurements.
Climate envelope
Use the optimum band for screening normal crop development and the absolute range as an outer tolerance boundary. Accumulated heat still depends on the local planting window and daily temperatures.
| Requirement | Profile value |
|---|---|
| Optimum temperature | 12–20°C |
| Absolute temperature range | 7–25°C |
| Heat to maturity | 1,500 growing degree days above a 4°C base |
| Photoperiod | Long-day response; 12-hour critical daylength |
| Vernalisation | Required; 10 reference days |
Soil and pH
| Requirement | Profile value |
|---|---|
| Optimum pH | 6–7 |
| Tolerated pH range | 4.5–7.8 |
| Waterlogging tolerance | Intolerant |
An intolerant rating means drainage is a screening constraint. Check infiltration, perched-water risk, field outlets and the duration of saturation before committing land.
Water
| Requirement | Profile value |
|---|---|
| Seasonal water requirement | 450 mm |
| Optimum rainfall band | 900–1,600 mm |
| Absolute rainfall range | 500–3,000 mm |
Irrigation becomes necessary when effective in-season rainfall is below the 450 mm seasonal requirement. Convert that gap into a field schedule only after accounting for soil water storage, application efficiency and local rainfall timing.
Nitrogen demand
The profile assigns Brussels Sprouts nitrogen-demand category 3, which translates to moderate demand. It is a relative category, not a fertiliser rate.
Set the field program from soil and tissue evidence, expected removals, prior-crop effects and local nutrient rules.
Crop-level reference profile
| Requirement | Profile value |
|---|---|
| Average yield | 16.5 t/ha reference average |
| Growing period | About 125 days to maturity, derived from 1,500 growing degree days above 4°C at a 16°C mean season temperature. Modelled from the crop profile. |
Where it grows well
These examples pass a stated temperature or rainfall comparison using representative regional values. Regional screening, not parcel-level.

Research basis
These papers support the qualitative interpretation of the crop profile. No paper-derived figure is used on this page; the named crop and region fields remain the only sources of displayed agronomic numbers.
- The Effect of Planting Times on Some Vegatable Characters and Yield Components in Brussels Sprouts (Brassica oleracea var. gemmifera)
Sprout initiation and harvest follow accumulated thermal time, so the planting window matters more than a fixed calendar date.
Taking this to a field decision
This profile cannot set planting depth, row spacing, seeding rate, cultivar choice, fertiliser rate, harvest timing, irrigation schedule or drainage design. Those decisions depend on cultivar, local practice and field conditions.
Use a coordinate-level audit, local field evidence and commercial terms before a land or lending decision.
