Seasonal context
Rainfall and the growing season in Siu Lek Yuen
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.

The catalog flowering or harvest months are not verified for this frost-free climate. Ask a local grower about the cultivar’s seasonal cycle.
Local growing check
Before choosing mashua for Siu Lek Yuen
- Many mashua forms need shortening days to develop tubers. A long warm period for vines does not prove that tubers will mature before cold weather; check the named cultivar’s local performance.
- June is the wettest month in the rainfall grid, averaging about 282 mm. Check how your own bed drains and plan watering around actual soil moisture; monthly rain totals are not an irrigation schedule.
The temperature and rainfall tables on this page show the underlying climate estimates. How these suitability checks work · Record what happens in your garden.
Before you plant mashua
Use the calendar to plan ahead, then check the conditions in your own garden.
- Measure the soil at sowing depth. Aim for at least 10°C (50°F); the calendar estimates soil warmth from air temperatures and cannot measure your bed.
- In a frost-free climate, check seasonal rainfall, humidity and heat before planting. A month with suitable average temperatures can still be too wet, dry or hot for this crop.
- Harden off plants raised indoors: gradually expose them to outdoor light, wind and temperature before their final move into the bed.
- Use the maturity range on your seed packet when choosing a variety. Cold, short days and transplant stress can make harvest later than the calendar estimate.
Check the cultivar's tuber timing as well as its flowers
Choose a documented cultivar, suitable support and drained soil with moisture available. Keep the root zone protected from excessive drying. Flowering time and tuber development vary, so do not treat an ornamental display as proof of a mature crop.
Lift tubers carefully near the surface and protect saved planting stock from unsuitable winter conditions. Use established culinary preparation and try a small crop first, because the peppery flavour is not to everyone's taste. Record yield and kitchen acceptance separately.
What to record this season
Did tubers develop before damaging cold, and was their cooked flavour useful to you? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates
Frost-relative timing needs a dependable seasonal frost date. Siu Lek Yuen has no such date in this record, so this page compares monthly temperatures with the crop's model range instead. Local wet and dry seasons, day length and cultivar requirements still need a separate check.
The model uses a growing-temperature band for mashua between 10°C (50°F)50°F (10°C) and 25°C (77°F)77°F (25°C) — and in Siu Lek Yuen that is November to April, 6 months of the year, taken from this location's own monthly averages. The planting window begins near the start of this period.
Siu Lek Yuen sits in zone 11a, which is above the catalog range. Confirm the exact cultivar locally; a zone number alone cannot measure summer heat or winter chill. The calculated dates do not confirm that this crop is suitable here. Check cultivar requirements and local growing experience before planting.

How much frost will mashua tolerate?
Check the named variety and local forecast before exposing young growth. The catalog cold-damage figure is a reference, not a guarantee: plant age, acclimatisation, wind and the duration of a freeze affect damage.
