Seasonal context
Rainfall and the growing season in Silvan
March has the highest average precipitation (78 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 broad beans for Silvan
- March is the wettest month in the rainfall grid, averaging about 78 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 broad beans
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 the cooler season for flowers and pod filling
Choose a variety for your intended sowing season and mature height. Give taller plants support before wind bends stems loaded with pods.
Inspect tender shoot tips for aphids and check whether flowers are setting pods. Hot, dry conditions can reduce yield even when the plant remains alive.
Pick pods at the stage you intend to eat, checking a sample rather than relying on pod length alone. Mature dry beans are a different harvest and preparation task from tender green seeds.
Growing in a container
Dwarf broad beans suit containers more readily than tall field types. Keep the pot stable and provide water while the pods fill.
What to record this season
Did hot weather arrive before the pods filled? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates
Choose a variety for your intended sowing season and mature height. Give taller plants support before wind bends stems loaded with pods.
Cold tolerance varies with cultivar, plant age, acclimatisation and the duration of a freeze. A plant surviving frost does not mean its leaves, heads, flowers or developing crop will remain undamaged. Check the forecast and the variety's local advice.
This calendar uses frost-relative offsets as a starting point. Broad beans are timed for direct sowing 8 weeks before it, and this page simply resolves those offsets against the frost date computed for Silvan.
The median frost-free season here is 249 days, against 80 to 100 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.

Growing broad beans in Silvan
Can I grow broad beans in Silvan?
The calendar estimates a planting window, not a guarantee of success. March is the wettest month in the rainfall grid, averaging about 78 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 broad beans in Silvan?
Aim for 29 Jan - 19 Feb in an average year. If you would rather not gamble on the weather, wait until 13 Feb - 6 Mar - by then frost has finished in nine years out of ten.
When might broad beans be ready to harvest in Silvan?
The estimated period is 19 Apr - 9 May, based on 80 to 100 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 broad beans tolerate?
Cold tolerance varies with cultivar, plant age, acclimatisation and the duration of a freeze. A plant surviving frost does not mean its leaves, heads, flowers or developing crop will remain undamaged. Check the forecast and the variety's local advice.
