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.

Local growing check
Before choosing cassava for Siu Lek Yuen
- 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 cassava
Use the calendar to plan ahead, then check the conditions in your own garden.
- Measure the soil at sowing depth. Aim for at least 20°C (68°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.
Treat cassava as a long-season crop with essential processing
Use suitable healthy planting material in a sunny, drained site with room for a large shrub. Keep the cultivar identified and distinguish edible-root production from an ornamental container plant.
Cassava can contain dangerous cyanogenic compounds, especially when raw. Use a known food cultivar and established local processing guidance; simply calling a variety sweet does not make raw roots safe. Do not improvise preparation of an unknown or bitter cultivar.
What to record this season
Did the named cultivar form usable roots, and was established processing guidance available? 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 cassava between 20°C (68°F)68°F (20°C) and 32°C (89.6°F)89.6°F (32°C) — and in Siu Lek Yuen that is March to November, 9 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 is zone 11a, within the crop's general range. This is an initial cold-hardiness check; cultivar, exposure, drainage and unusual winters can still change the outcome.
