  1. Sowing and germination (BBCH 0)
  2. Planting out and establishment (BBCH 1): Move on under glass, or outdoors into a warmed mound in early summer, spaced about 30cm each way or 25cm apart in rows 35cm apart; full sun and a sheltered spot (RHS, GrowVeg).
  3. Flowering and pegging (BBCH 6): Small yellow flowers veined with orange appear mid- to late summer; after pollination the flower stem elongates and pushes the ovary underground, where the pod develops (RHS).
  4. Pod fill and harvest (BBCH 8): Needs at least 120 days of hot weather to crop well. Yellowing foliage signals harvest: lift the whole plant and leave it to dry on the soil surface with pods attached for several days (GrowVeg).

Harvest & Storage

Peanut pods in shell, cracked open, shelled and peeled kernels — “Peanuts (Arachis hypogaea) - in shell, shell cracked open, shelled, peeled” by Ivar Leidus is licensed under CC BY-SA 4.0.

When to pick: Clemson: green/boiling peanuts "typically mature from 90 to 110 days after planting"; dry/roasting peanuts "130 to 150 days after planting". For boiling peanuts, "pods that are not filled by the kernel are too young; pods with a dark internal hull color are overmature". For roasting peanuts, ready "when at least 65 percent of the pods have turned dark inside the hull and the seed coats are pink to copper-red in color".

Storage

Dried pods store long-term; green/boiling type used fresh

Peanut late leaf spot

Nothopassalora personata

Tropical Plant Pathology (Springer, peer-reviewed): major foliar disease, yield loss 40-50% in severely affected/defoliated plants.

Peanut Sclerotinia blight

Sclerotinia minor

Oklahoma State Extension: "The fungus Sclerotinia minor primarily causes Sclerotinia blight of peanuts."

Tobacco thrips

Frankliniella fusca

Tobacco thrips (Frankliniella fusca) is the primary vector of Tomato Spotted Wilt Orthotospovirus in Southeastern US peanuts, also causing direct feeding injury.

Lesser cornstalk borer

Elasmopalpus lignosellus

UGA Extension: in the US south-east the lesser cornstalk borer chews on the pods, contaminating the crop with aflatoxin-producing Aspergillus. It thrives in hot, dry conditions on sandy soils and does poorly wherever…

Plan your Peanuts planting

When to sow and plant Peanuts 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.

Frequently Asked Questions

How long do peanuts take to grow?

Typically 90–150 days, depending on cultivar and growing conditions.

What soil pH do peanuts need?

A pH of about 5.8–6.5. 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 peanuts?

Our data links 2 diseases and 2 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 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.
