Chives will not survive below about 2°C, so timing follows your local last frost date rather than a fixed month.

This is a frost-tender crop — it will not survive below about 2°C — so the growing year is built around starting it under cover and moving it out only once the risk of frost has passed.

The short answer

Site
soil pH 6–6.6
Biggest risk
Onion downy mildew

Growth Stages

Stage BBCH Notes
Sowing or division 0 Sow indoors in early spring 0.5-1cm deep, or direct outdoors; thin seedlings to 15-20cm apart. Alternatively divide an established clump every three to four years, pulling it apart and replanting sections 15cm apart in spring or autumn -- much faster than starting from seed. RHS.
Establishment 3 A young clump bulks up through its first season; avoid heavy cutting until it is well established. RHS.
Cut-and-come-again cropping 5 Snip with scissors just above the base whenever leaves are needed, ideally in the morning -- the more often the plant is cut, the more new leaves it produces, right through spring to autumn. RHS.
Flowering & winter care 6 Decorative pompom flowerheads appear in late spring and summer and are themselves edible, scattered into salads. Established clumps die back for winter; potting one up and bringing it indoors onto a sunny windowsill extends the harvest through the cold months. RHS.

Harvest & Storage

When to pick: Cut-and-come-again herb; snip leaves regularly from spring to autumn to encourage fresh growth

Diseases

Onion downy mildew

The full list of 10 sources behind this guide (GBIF, NC State Extension, Royal Horticultural Society) is in the references of our UK guide to chives; they describe the plant itself, which is the same wherever it grows.

Frequently Asked Questions

What soil pH do chives need?

A pH of about 6–6.6. 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 chives?

Our data links 2 diseases and 4 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.

Every growing guide is checked against RHS, USDA Cooperative Extension, and other named horticultural authorities before publishing.

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.
