Seasonal context
Rainfall and the growing season in Siverek
December has the highest average precipitation (62 mm); August has the lowest (1 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 potatoes for Siverek
- December is the wettest month in the rainfall grid, averaging about 62 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 potatoes
Use the calendar to plan ahead, then check the conditions in your own garden.
- Measure the soil at sowing depth. Aim for at least 7°C (44.6°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.
Choose early or maincrop potatoes before planning the bed
Early varieties use the bed for less time and suit smaller plots. Maincrops need a longer season and more space, but produce larger potatoes suitable for storage. Choose for your available season as well as cooking preference.
Sprouting early seed potatoes in a bright, frost-free place can give them a head start. Protect emerging shoots from frost and cover developing tubers with soil or mulch so they are not exposed to light.
Check for blight during wet weather and use locally suitable resistant varieties where the disease is common. Rotate the growing area; a planting date alone does not prevent soil-borne problems.
Growing in a container
Early varieties suit large containers or potato sacks with drainage. Add growing medium as shoots develop and check moisture regularly.

Why these dates
Early varieties use the bed for less time and suit smaller plots. Maincrops need a longer season and more space, but produce larger potatoes suitable for storage. Choose for your available season as well as cooking preference.
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. Potatoes are timed for direct sowing 2 weeks before it, and this page simply resolves those offsets against the frost date computed for Siverek.
The calendar also applies a soil-warming estimate derived from historical air temperatures. Where that estimate is later than the frost-based date, it delays the window. Soil in your own garden can warm earlier or later; a thermometer at sowing depth is a better final check. Cold, wet conditions can slow germination and increase decay risk.
The median frost-free season here is 230 days, against 70 to 120 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.

Growing potatoes in Siverek
Can I grow potatoes in Siverek?
The calendar estimates a planting window, not a guarantee of success. December is the wettest month in the rainfall grid, averaging about 62 mm. Check how your own bed drains and plan watering around actual soil moisture; monthly rain totals are not an irrigation schedule.
When should I plant potatoes in Siverek?
Aim for 19 Mar - 2 Apr in an average year. If you would rather not gamble on the weather, wait until 3-17 Apr - by then frost has finished in nine years out of ten.
When might potatoes be ready to harvest in Siverek?
The estimated period is 28 May - 17 Jul, based on 70 to 120 days from the modeled planting date. Cultivar, planting material and growing conditions can change this interval; check the plant as well as the calendar.
How much frost will potatoes tolerate?
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.
