Broad Beans
How do I grow broad beans from seed?
The short answer
Sow broad beans in a sunny bed that drains well. For many home-garden varieties, about 5 cm (2 in) deep and 15–20 cm (6–8 in) apart is a useful starting point. Follow the packet if it differs. Support tall plants before they lean, and check root-zone moisture as flowers and pods develop.
Once you have a suitable sowing date, set up the bed so seedlings have room and stems stay upright as pods fill.
Diagnostic snapshot
What to check before you act
What you are seeing
- Direct sowing
- Individual pots or deep modules
Check first
Check that the bed receives direct sun and that water drains after rain.
Hold off for now
Hold off on routine high-nitrogen feeding.
Investigate further if
If several plantings grow poorly in the same bed despite suitable moisture, ask a local gardening service about a soil test or a plant diagnosis before adding fertiliser or lime.
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 a sowing setup
| Setup | When it helps | What to check |
|---|---|---|
| Direct sowing | The bed is workable and drains freely | Use seed packet depth and spacing and label the row. |
| Individual pots or deep modules | The bed is too wet to work or local advice favours a protected start | Use drainage holes and harden the seedlings off before planting out. |
| Tall variety in an exposed bed | Upright plants will need support as pods fill | Install stakes and string before stems lean. |
What to check first
- Check that the bed receives direct sun and that water drains after rain.
- Review the packet for mature height and row spacing. Leave enough room to pick pods and allow air to move between plants.
What to do now
- Make holes in prepared soil, sow one seed per hole at the recommended depth and label the row. If starting under cover, use individual containers with drainage holes. Gradually acclimatise seedlings before planting them out.
- For a single row, the RHS uses about 45 cm (18 in) between rows. Keep room to reach the plants and set up their supports before they lean.
- Put stakes at the ends of the row and run string along both sides before tall stems begin to flop. Add a higher line if new growth needs it.
- Check moisture below the surface at flowering and pod set. Water at soil level if that layer is drying. Containers and light soil can dry faster than a garden bed.
GardenSolved checkpoint
Do not do this yet
- Hold off on routine high-nitrogen feeding.
- Broad beans can form nitrogen-fixing root nodules in association with soil bacteria.
- Base amendments on the growing medium, a soil test or local guidance.
Confirm the likely cause first, then choose the treatment.
Choose seed for the crop you want
For fresh beans to shell, choose a culinary variety sold as sowing seed. Use packet guidance for the cultivar rather than borrowing spacing from a cover-crop guide.
When to get help
If several plantings grow poorly in the same bed despite suitable moisture, ask a local gardening service about a soil test or a plant diagnosis before adding fertiliser or lime.

Check again when you return
- Check that the bed receives direct sun and that water drains after rain.
- Review the packet for mature height and row spacing. Leave enough room to pick pods and allow air to move between plants.
Tip: photograph the same area from a similar angle so the visible pattern is easier to compare.
