Stage BBCH Notes
Sowing and germination 0 Sow under cover in late winter or direct outdoors from mid-spring, seed 3-4cm deep in rows 30cm apart, about 8-10g of seed per square metre; UK trials found heavier yields from an early April sowing (Bite Sized Gardening).
Establishment and staking 1 Sprawling habit reaching 40-50cm; stake young plants with twiggy pea sticks or canes and string if space is limited, to keep growth more upright (Bite Sized Gardening).
Flowering and pod set 6 Water during dry spells as pods develop; otherwise needs little attention (Bite Sized Gardening).
Pod ripening and harvest 8 Harvest once pods have turned brown, then dry and store the small lens-shaped seeds (Bite Sized Gardening).

Aphididae (various spp.)

Pea aphid (Acyrthosiphon pisum) and cowpea aphid (Aphis craccivora) are key pests of lentil, feeding on tender leaves/stems/pods.

Pea and bean weevil

Sitona lineatus

ICRISAT: Sitona spp. leaf weevils are major lentil pests, adults creating characteristic semicircular notches along leaf edges.

Plan your Lentils planting

When to sow and plant Lentils depends on your own frost dates. Check the Canada vegetable planting calendar. To work out where it fits in your beds, sketch your plot in the free Garden Layout Planner.

Every growing guide is checked against RHS, USDA Cooperative Extension, and other named horticultural authorities before publishing. How we check our facts.

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.
