Seasonal context
Rainfall and the growing season in Üsküdar
December has the highest average precipitation (83 mm); July has the lowest (20 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 lambs lettuce for Üsküdar
- December is the wettest month in the rainfall grid, averaging about 83 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 lambs lettuce
Use the calendar to plan ahead, then check the conditions in your own garden.
- Measure the soil at sowing depth. Aim for at least 4°C (39.2°F); the calendar estimates soil warmth from air temperatures and cannot measure your bed.
- Frost tolerance does not make saturated or frozen soil suitable for planting. Wait until the bed can be worked without smearing or compacting it.
- 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.
Use cool conditions for tender corn-salad rosettes
Sow modest batches into a prepared bed and keep moisture available during establishment. Summer shade can slow bolting, while winter crops benefit from a suitable sheltered position and protection in severe weather.
Harvest clean young rosettes or tender leaves before flowering makes the crop less useful. Plants can self-sow if left to seed; decide whether volunteers fit your bed plan. Record which sowing remains tender longest.
What to record this season
Which sowing produced usable rosettes before plants began to flower? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates
Sow modest batches into a prepared bed and keep moisture available during establishment. Summer shade can slow bolting, while winter crops benefit from a suitable sheltered position and protection in severe weather.
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. Lambs lettuce are timed for direct sowing 10 weeks after it, and this page simply resolves those offsets against the frost date computed for Üsküdar.
The median frost-free season here is 303 days, against 60 to 80 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
