Import into Apple Calendar, Google Calendar or Outlook. Dates use the selected risk level and are planning estimates, not frost alerts.

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.

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.

For soybeans, also check drainage, sunlight and cultivar requirements. See the rainfall context above; humidity, irrigation and local pest pressure are not calculated.

Local growing check

Before choosing soybeans for Sīnah

March is the wettest month in the rainfall grid, averaging about 63 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 soybeans

Use the calendar to plan ahead, then check the conditions in your own garden.

Measure the soil at sowing depth. Aim for at least 15°C (59°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 a dry-soybean crop rather than an edamame harvest

Use a sunny, drained bed and consider an inoculant specifically labelled for soybeans where appropriate. Excess nitrogen can encourage weak, lush growth. Maintain moisture during establishment and pod development without waterlogging roots.

Let pods mature and dry, then finish drying sound harvested seed in suitable ventilated conditions before storage. Record whether pods matured together and whether wet harvest weather caused losses. Use proper food preparation for mature beans.

What to record this season

Did the cultivar produce uniformly mature dry seed before persistent wet or cold weather? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates

Use a sunny, drained bed and consider an inoculant specifically labelled for soybeans where appropriate. Excess nitrogen can encourage weak, lush growth. Maintain moisture during establishment and pod development without waterlogging roots.

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. Soybeans are timed for direct sowing 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Sīnah.

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 256 days, against 85 to 120 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.

Growing soybeans in Sīnah

Can I grow soybeans in Sīnah?

The calendar estimates a planting window, not a guarantee of success. March is the wettest month in the rainfall grid, averaging about 63 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 soybeans in Sīnah?

Aim for 12 Apr - 3 May in an average year. If you would rather not gamble on the weather, wait until 16 Apr - 7 May - by then frost has finished in nine years out of ten.

Can I plant soybeans earlier in Sīnah?

The historical frost estimate is 3 Apr. For Soybeans, an air-temperature model estimates soil warmth of about 15°C (59°F) around 12 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 soybeans be ready to harvest in Sīnah?

The estimated period is 6 Jul - 10 Aug, based on 85 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.
