Planting calendar for Shenzhen
Shenzhen has no dependable frost in the record, so the growing year here is bounded by heat and rain rather than by cold.

These windows do not model rainfall, humidity, drainage or cultivar needs; check those before planting.

Each bar is a model window, not a deadline. Windows for crops needing a winter suitability check are conditional; open the crop page before planting. Unverified flowering and harvest predictions are withheld. Tap or hover a bar for its dates, or follow a crop name for the full timing and a harvest estimate. The blue wash is the measured weekly chance of frost across the whole record. There is also a printable one-page version of this calendar for the shed wall.

Questions about frost in Shenzhen
What hardiness zone is Shenzhen in?
Shenzhen sits in USDA-equivalent zone 11a, based on a mean annual extreme minimum of 6.2°C (43.2°F). Perennials rated to this zone or lower should survive an average winter here.
Can I trust these dates exactly?
They are statistics, not forecasts. They describe what happened across 30 years of records at this location and say nothing about this particular spring. Frost is also intensely local: a low-lying or exposed garden can run a week behind the figures on this page.
Seasonal context
Rainfall and the growing season in Shenzhen
June has the highest average precipitation (282 mm); December has the lowest (25 mm). Compare this pattern with the planting windows and your water supply.
During wetter months, check that beds and containers drain after heavy rain. During drier months, plan how you will keep seeds and new transplants watered. Monthly averages can hide long dry spells and intense storms; they do not show soil moisture, humidity or this week's weather.
Frost-free does not mean every month is suitable. In tropical and monsoon climates, rainfall, heat, drainage and the cultivar can set the practical growing season. Match the temperature window to these conditions and check advice from a local grower before buying planting material.
