Horticulture in Latin America: Andes & Temperate South
A southern-hemisphere temperate belt with Mediterranean central Chile, cold Patagonia and the high Andes; the garden year runs September–April. Winter rain in Chile and summer rain in the pampas mean the same plant list does not travel far.

USDA zones6–10
Growing seasonSeptember to April
RainfallWinter rain in central Chile; summer rain on the pampas

The climate, read as a season
Peak growth falls in Jan, Feb, Oct, Nov, Dec; dormancy in May, Jun, Jul. Hard frost is confined to Apr, May, Jun, Jul, Aug, and the driest months are Jan, Feb, Mar, Oct, Nov, Dec. Those three patterns decide the planting calendar more than the annual average temperature.
| Season | Conditions | What it means |
|---|---|---|
| Spring Sep · Oct · Nov | Peak growth dry season · light frost | Plant, but keep protection for tender crops. |
| Summer Jan · Feb · Dec | Peak growth dry season · frost-free | The main planting and sowing window. |
| Autumn Mar · Apr · May | Slow growth drier spell · hard frost | Maintain, harvest and prepare the next season. |
| Winter Jun · Jul · Aug | Dormancy steady rain · hard frost | Dormant: prune, plan and protect. |
What the climate demands
- The Andes create sharp microclimates: frost, hail and UV change within a few hundred metres of altitude.
- Central Chile's dry summer and the pampas' summer rain demand different irrigation and species strategies.
- Patagonian wind and volcanic soils limit trees to wind-firm, lime-tolerant species.
