Quick Facts
| Factor | Value |
|---|---|
| Soil pH | 6 - 7 |
| Sunlight | 6-10 hours direct sun |
| Germination temp | 3°C |
| Optimal growing temp | 18-28°C |
| Soil texture | RHS: "rich, free-draining soil"; before sowing "fork in plenty of well-rotted manure or home-made garden compost - at least two bucketfuls per square metre/yard". |
| Drainage | RHS: free-draining, in a "sunny, sheltered site". |
| Lifecycle | Hardy annual legume; semi-hardy -- hardy longpod cultivars (e.g. Aquadulce Claudia) withstand light frost and are sown outdoors in autumn to overwinter, but not heavy frost or hard freezes. |
| Edible parts | pods (shelled or whole), young shoot tips |
When to plant in Canada
Canada. Broad beans are sown in SPRING in Canada, as early as the soil can be worked. The autumn-sown overwintering strategy that UC and WSU describe belongs to mild-winter regions — UC notes that excessively cold winters do not favour the crop — and a Canadian winter is well beyond what an autumn-sown plant will carry through outside the mildest coastal pockets. Sowing early matters at the other end too: UC records that the plants do poorly in warm weather, when they become susceptible to pests and diseases, so the aim is to have pods set before midsummer heat. Sow 3-5 cm deep, 15-20 cm apart, in rows 45 cm apart. Broad beans are among the most cold-tolerant of the legumes, which is what lets them go in well before beans or peas would survive.
Soil & Growing Conditions
Growth Stages
| Stage | BBCH | Notes |
|---|---|---|
| Sowing & Establishment | 0 | Sow 5-7.5cm (2-3in) deep, or start indoors in pots/modular trays at 5cm (2in) deep with the seed scar facing downwards (RHS). Space plants 15-23cm (6-9in) apart within the row; grow in double rows 23cm (9in) apart with 60cm (2ft) between each double row, or single rows 45cm (18in) apart (RHS). Two UK sowing windows: hardy longpod cultivars (e.g. 'Aquadulce Claudia') can be autumn-sown in October or November in mild, sheltered sites to overwinter as small seedlings for the earliest crop; the main sowing is spring, from February through April and even early May, for harvests through summer (RHS). Fava/broad bean is a semi-hardy annual that withstands light frosts but not hard freezes (Univ. of Maryland). Seed germinates once average soil temperature at sowing depth reaches about 3-5°C (Saskatchewan Pulse Growers). |
| Vegetative Growth | 3 | Most broad beans need staking as they grow: insert sturdy stakes at each corner of the row and every 1.2m (4ft) along it, then run string around the stakes at 30cm (1ft) intervals from the ground (RHS). Dwarf varieties such as 'The Sutton' (to 45cm/18in) generally support each other, especially in double rows, and need no staking (RHS). Plants in the ground do not usually need regular watering at this stage unless grown in light, free-draining soil (RHS). |
| Flowering | 6 | Give plants a good soak as flowering begins, and again two weeks later - this single step "greatly improves the harvest" (RHS). Keep watering consistent through this stage, especially in light or free-draining soil (RHS; Univ. of Maryland: "keep the root zone moist by watering deeply and regularly during dry periods"). |
| Pod Development | 7 | Once the lowest set of flowers has formed small pods, pinch out the shoot tips at the top of each plant - this channels energy into pod development and reduces blackfly (black bean aphid) infestations, which target the soft growing tips (RHS). The pinched tips are edible and can be cooked like spinach (RHS). Keep the root zone moist, watering deeply and regularly during dry periods - water more frequently once pods begin to develop (Univ. of Maryland). |
| Ripening & Harvest | 8 | Pick pods when they are full but still relatively small - small beans are sweeter and more tender than large ones. Check the scar on the bean: it should still be white or green, not black (RHS). Young, immature pods can be picked whole at about 7cm (3in) long and cooked like French beans (RHS). |
| Senescence & End of Crop | 9 | Once harvesting has finished, cut plants down to the base and compost the top growth. As a legume, broad bean fixes nitrogen from the air at its roots - leave the roots in the ground after cutting to boost soil nitrogen levels for the next crop (RHS). |

Frequently Asked Questions
What soil pH do broad beans need?
A pH of about 6–7. That span reflects genuine variation between the authorities we cite rather than a single agreed figure — the References section lists each source's exact range.
What problems affect broad beans?
Our data links 2 diseases and 3 pests to this crop. See the sections above for each one and how to manage it.
Plan next season before the problems start
Short-season growing is arithmetic before it is technique: days to maturity against frost-free days decides what will finish at all. The Canada Garden Planner does that subtraction for your region before you sow.

How this guide is put together
The growing data on this page — sowing windows, pests, diseases, soil and site requirements — comes from named horticultural sources, listed in References below, checked against Canadian hardiness-zone and frost-date data, with provincial agriculture and university extension sources cited directly where one exists for a crop. An automated pipeline assembles that verified data into the page you're reading: it selects which facts to lead with and builds the surrounding prose and layout. It does not invent a date, a source or a number — where a verified value for a field isn't available, the page leaves it out rather than guessing. A person reviews and publishes each page; nothing goes live unverified.
