Seasonal context
Rainfall and the growing season in Bitlis
April has the highest average precipitation (88 mm); August has the lowest (3 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.

Local growing check
Before choosing kai-lan for Bitlis
- April is the wettest month in the rainfall grid, averaging about 88 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 kai-lan
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.
- Check the local overnight forecast before planting out. Delay planting or keep protection ready if frost is forecast, even after the historical last-frost date.
- 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.
Cut tender kai-lan flowering stems before they become coarse
Choose a cultivar for your local temperature pattern and keep the bed fertile, moist and drained. Some selections tolerate warmer conditions than many other brassicas, but local performance still varies.
Cut usable young flowering shoots before stems become fibrous. Leave healthy growth where the cultivar is intended to produce side shoots, and inspect the regrowth before planning a second harvest. Record stem tenderness as well as length.
What to record this season
At what stage were stems tender, and did useful side shoots develop after cutting? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates
Choose a cultivar for your local temperature pattern and keep the bed fertile, moist and drained. Some selections tolerate warmer conditions than many other brassicas, but local performance still varies.
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.
This calendar uses frost-relative offsets as a starting point. Kai-lan are timed for direct sowing 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Bitlis.
The median frost-free season here is 191 days, against 50 to 70 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
