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 rhubarb for Siu Lek Yuen
- The coolest monthly mean is about 16.4°C. This is a warm-winter screening signal, not a measured chill-hour total. Confirm the exact cultivar with a local grower before buying; the dates below only describe the temperature model.
- 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.

Before you plant rhubarb
Use the calendar to plan ahead, then check the conditions in your own garden.
- 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.
- Check the cultivar’s winter chill requirement with a local nursery. Hardiness zones measure winter cold, not chill hours; this site does not calculate a local chill-hour total.
- Check mature size, drainage and cultivar suitability before choosing a permanent position. A suitable planting window does not guarantee long-term survival or fruiting.
Establish the crown before taking a regular rhubarb harvest
Choose a permanent, drained position with enough room for large leaves. Moisture should support active growth without leaving the crown in soggy soil. Keep a newly planted or divided crown separate in your records from an established clump.
Take usable stalks with a gentle pull and twist, leaving plenty of foliage to replenish the plant. Stop sustained picking early enough for recovery rather than stripping it for the whole season. Discard the leaf blades, which are not edible.
What to record this season
Did the crown retain strong foliage after picking and return vigorously the following season? 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 rhubarb between 5°C (41°F)41°F (5°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.
One caution specific to warm climates: this crop needs roughly 500 hours below 7.2°C (45°F)45°F (7.2°C) over winter before it will flower properly, and the coldest month in Siu Lek Yuen averages 16.4°C (61.5°F)61.5°F (16.4°C). This site does not calculate local chill hours. Check the exact cultivar with a knowledgeable local nursery; a monthly average cannot establish that its chilling requirement is met.
The general establishment guide is around year 2, under suitable conditions. This is not a prediction for this location; cultivar, winter conditions and care determine whether it crops reliably.
