Broad Beans
When should I sow broad beans?
The short answer
Sow a hardy autumn variety outdoors only where local conditions suit overwintering and the bed is sheltered and drains freely. In a cold, exposed or persistently wet garden, plan for late winter under cover or spring outdoors once the soil is workable. November is a useful sowing window in some places. Use the local window on your seed packet or in a regional growing guide.
Use your seed packet and the condition of your bed to choose between a November sowing and an early start later in the season.
Diagnostic snapshot
What to check before you act
What you are seeing
- Mild winter, sheltered bed, freely draining soil and a variety sold for autumn sowing
- Wet or exposed bed, with a bright sheltered place for young plants
Check first
Read the packet for the variety and its recommended sowing season.
Hold off for now
Hold off on sowing into frozen or saturated ground, even if the calendar says November.
Investigate further if
Ask an Extension office or local gardening service for the sowing window if your area has sharp winter swings or if seed guidance is for another climate. The RHS describes autumn sowing in mild British gardens. Sonoma County guidance includes autumn sowing into November. Oregon State guidance west of the Cascades gives an earlier example, in late September or early October.
Photograph this before you act
- Photograph the soil surface and root-zone or container context; do not disturb roots just to take a photo.
- Take one close-up of the clearest symptom and one wider view that shows the surrounding area for comparison.
Next best check
Check two visible clues before you act.
This mini-check narrows the match using the same canonical diagnostic clues as this answer. It does not confirm a diagnosis from one or two clicks, and it does not make a photo-only diagnosis.
Two quick observations can tell you whether to keep reading this diagnosis closely or compare other possibilities first.
Choose the situation that fits
| What you have | What to do |
|---|---|
| Mild winter, sheltered bed, freely draining soil and a variety sold for autumn sowing | Direct sow in the local autumn window. ‘Aquadulce Claudia’ is one example of an overwintering variety. |
| Wet or exposed bed, with a bright sheltered place for young plants | Plan a late-winter sowing in individual pots or modules under cover, then harden plants off before planting out. Follow local advice if considering an earlier protected sowing. |
| Frozen ground, recurring winter saturation or a spring variety | Wait for the local late-winter or spring window. Sow outdoors when the soil can be worked without smearing or compacting it. |
What to check first
- Read the packet for the variety and its recommended sowing season.
- After rain, check the soil at sowing depth. Sticky saturated soil beneath a dry surface still drains poorly.
What to do now
- If autumn sowing suits your site, use the depth and spacing on the packet.
- Keep a few seeds for spring if overwintering is uncertain.
- If you miss the autumn window, a fast-maturing variety sown under cover in late winter can still give an early harvest.

Do not do this yet
- Hold off on sowing into frozen or saturated ground, even if the calendar says November.
Confirm the likely cause first, then choose the treatment.
Regional examples
November can suit sheltered mild British gardens and parts of coastal California. Oregon State’s example west of the Cascades places suitable autumn sowing earlier, in late September or early October. Use your own local window.

Your baseline
- Mild winter, sheltered bed, freely draining soil and a variety sold for autumn sowing
- Wet or exposed bed, with a bright sheltered place for young plants
Check again when you return
- Read the packet for the variety and its recommended sowing season.
- After rain, check the soil at sowing depth. Sticky saturated soil beneath a dry surface still drains poorly.
Tip: photograph the same area from a similar angle so the visible pattern is easier to compare.
