Seasonal context
Rainfall and the growing season in Tatvan
April has the highest average precipitation (81 mm); August has the lowest (4 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 buckwheat for Tatvan
- April is the wettest month in the rainfall grid, averaging about 81 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 buckwheat
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.
Decide between a flowering cover crop and a grain harvest
Use suitable warm-season conditions and a drained bed. Excessive nitrogen can encourage growth that is harder to manage. If cover is the aim, decide when to terminate before seed becomes unwanted volunteer plants.
For grain, assess uneven ripening and collect mature seed with a plan for drying, cleaning and dehulling. Do not treat the whole green plant as interchangeable with edible groats. Record whether grain processing is practical at your scale.
What to record this season
Was the planting more useful as soil cover and flowers or as a cleaned grain crop? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates
Use suitable warm-season conditions and a drained bed. Excessive nitrogen can encourage growth that is harder to manage. If cover is the aim, decide when to terminate before seed becomes unwanted volunteer plants.
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. Buckwheat are timed for direct sowing 1 weeks after it, and this page simply resolves those offsets against the frost date computed for Tatvan.
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 205 days, against 70 to 90 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.

Growing buckwheat in Tatvan
Can I grow buckwheat in Tatvan?
The calendar estimates a planting window, not a guarantee of success. April is the wettest month in the rainfall grid, averaging about 81 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 buckwheat in Tatvan?
Aim for 25 Apr - 9 May in an average year. If you would rather not gamble on the weather, wait until 2-16 May - by then frost has finished in nine years out of ten.
Can I plant buckwheat earlier in Tatvan?
The historical frost estimate is 21 Apr. For Buckwheat, an air-temperature model estimates soil warmth of about 10°C (50°F) around 25 Apr. This is not a soil measurement or a forecast. Check your bed at sowing depth; cold, wet conditions can slow growth and increase decay risk.
When might buckwheat be ready to harvest in Tatvan?
The estimated period is 4-24 Jul, based on 70 to 90 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 buckwheat 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.
