18–30 °C active growth
Growth slows below about 10–12 °C and is at risk near freezing; prolonged heat above ~38 °C can cause sunburn, flower injury and reduced set. Verify frost and heat extremes from local station data, not global averages.
Start with the crop's baseline, then adapt calendar, cultivar mix, water delivery and protection to your site's heat, frost, rain, aridity, humidity, elevation and pH.
These ranges define where active growth, flowering and fruit development are plausible. Your soil, drainage, microclimate and management determine what actually succeeds.
Growth slows below about 10–12 °C and is at risk near freezing; prolonged heat above ~38 °C can cause sunburn, flower injury and reduced set. Verify frost and heat extremes from local station data, not global averages.
Young growth and open flowers are most vulnerable. A single advective frost or radiation frost pocket can damage tissue at 0 to –2 °C; duration, wind and prior hardening matter. Protected sites, elevation and structure change exposure, not biology.
High irradiance and canopy temperature drive bleaching, corking and fruit scald on exposed faces. Orientation, shade level, whitewash or net, and pruning balance light with protection and must be trialed locally.
Seasonal totals of 600–1 300 mm may suffice where irrigation bridges dry periods, but free drainage is decisive. Roots demand oxygen; mound or raised-bed where water ponds, and design surface drains before planting.
Prolonged leaf wetness, overhead wetting and dense canopies extend infection conditions for spot, canker and fruit rots. Space, airflow, training, drainage and zoned drip influence disease load alongside chemistry.
Elevation shifts diurnal range, frost risk and season length. Alkaline, sodic or strongly acid soils limit nutrition and drainage; laboratory tests guide adjustment. The practical field target is pH 6.0–7.0 where feasible, alongside salinity and structure.

Use this to sequence site checks and guide links before ordering plants or fixing spacing. Each row starts from observable site evidence.
| If the site shows | Check first (test) | Threshold / action prompt | Open guide |
|---|---|---|---|
| Frost at or near ground <1 m | 10-year frost dates, on-site minima, slope vs hollow | Frost on >20% of nights in shoulder season → map microclimates; greenhouse only | Field plan — site |
| Dry season >2 h sunburn on exposed stems | Canopy temperature, shade trial 20–35%, irrigation uniformity | Scorch recurring → nets/whitewash trialed; verify EC and leaching | Crop care |
| Heavy rain or perched water table | Pit drainage test, prolonged wet-feet after 24–48 h | Ponding persists → mounds, drains, reduce overhead wetting | Field plan — architecture |
| Irrigation EC >1.2 dS/m or SAR concern | Water test (EC, SAR, pH) plus soil test | Salinity rising → blend/source review; leaching only where lawful | Water & roots |
| Prolonged humidity & leaf wetness | Hours wet, canopy density, disease hotspot map | Many wet nights → thin canopy, widen spacing, zonal drip | IPM |
| pH <5.8 or >7.5 | Representative soil + water test | Outside 6.0–7.0 → amendment plan via qualified advice, not formula | Nutrition |
| Variable pollination set | Bagged vs crossed vs open bloom records per clone | Set <50% on self test → interplant verified pollen donor | Compatibility · Cultivar tool |
