Each window is a planning range. Check the forecast, soil and cultivar before planting; a later date is not automatically safer in hot or wet conditions.
Plant out
2 Nov - 3 Apr
Any time the plant is dormant and the ground is neither frozen nor waterlogged: after leaf fall in autumn, or at the end of winter before growth restarts.

Seasonal context
Rainfall and the growing season in Erciş
April has the highest average precipitation (66 mm); August has the lowest (8 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 rosemary for Erciş
- April is the wettest month in the rainfall grid, averaging about 66 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 rosemary
Use the calendar to plan ahead, then check the conditions in your own garden.
- Frost tolerance does not make saturated or frozen soil suitable for planting. Wait until the bed can be worked without smearing or compacting it.
- Check mature size, drainage and cultivar suitability before choosing a permanent position. A suitable planting window does not guarantee long-term survival or fruiting.
Choose the shrub shape and protect the roots from wet soil
Give it strong light and a freely draining root zone. Established rosemary tolerates dry conditions, but a newly planted shrub or a root-filled pot still needs moisture checks. Persistent wetness is a greater concern than a missed fertiliser application.
Cuttings or a named nursery plant preserve the selected habit more reliably than seed. Harvest leafy shoot tips and shape the plant lightly; do not rely on bare old wood to regenerate after a severe cut. Check the exact cultivar's winter tolerance before leaving a container outdoors.
What to record this season
Did winter wetness, cold exposure or pot drying cause the main loss of growth? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates
Give it strong light and a freely draining root zone. Established rosemary tolerates dry conditions, but a newly planted shrub or a root-filled pot still needs moisture checks. Persistent wetness is a greater concern than a missed fertiliser application.
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.
Rosemary are planted once and then left in place, so there is no sowing offset to resolve. What matters in Erciş is the shape of the year: this crop is dormant through the winter and is planted while it sleeps, any time between leaf fall in autumn and the restart of growth in spring, so long as the ground is neither frozen nor waterlogged. That is why the window below spans the cold months rather than sitting in the middle of the growing season.
Erciş sits in zone 6a, which is colder than the catalog range. Check a locally proven cultivar and a realistic protection plan before planting. The calculated dates do not confirm that this crop is suitable here. Check cultivar requirements and local growing experience before planting.
The general establishment guide is around year 1, under suitable conditions. This is not a prediction for this location; cultivar, winter conditions and care determine whether it crops reliably.
