How to Grow Wheats UK | Regional Planting Calendar

Regional Planting Calendar

Region	Sow
Southern England	early March to mid April
Midlands	early March to mid April
Northern England	early March to late April
Scotland	mid March to late April

Southern England - detail & sources

RHS states seed is sown in spring or autumn; taken here as the spring window for southern England.

Midlands - detail & sources

Same spring sowing window as elsewhere in the UK -- RHS rates wheat H5, hardy through most of the UK even in severe winters.

Northern England - detail & sources

Sowing window shifted about a week later than southern England for a cooler spring start -- RHS's H5 rating means winter cold is not a limiting factor even this far north.

Scotland - detail & sources

Sowing window shifted about two weeks later than southern England for Scotland's cooler, later spring -- RHS's H5 rating still applies, so this remains a reliable outdoor crop.

Quick Facts

Factor	Value
Sunlight	6-8 hours direct sun
Minimum survivable temp	-15C
Drainage	Moist but well-drained (RHS); NC State: good drainage, moderately fertile soil not subject to flooding.
Lifecycle	Annual grass. RHS rates it H5, hardy in most UK locations even in severe winters.
Edible parts	seeds

At a Glance

Growth Stages

Stage	BBCH	Notes
Sowing	0	RHS: propagate by seed, sown in spring or autumn. NC State: choose soft spring wheat for spring sowing or hard winter wheat for autumn; broadcast seed about 3in apart, 0.5in deep -- winter wheat sown too late leaves roots underdeveloped for winter survival.
Establishment	3	NC State: best results come from moderately fertile, well-drained soil not subject to flooding; where Hessian fly is a known local risk, delay planting until after the first fall frost.
Overwintering and spring growth	3	RHS: no pruning required; rated H5, hardy in most of the UK even through severe winters, so autumn-sown wheat is not usually at risk from UK winter cold once properly established.
Ripening and harvest	8	NC State: ready when stems turn golden yellow and seeds harden; cut stalks near the base, bundle, and hang in a well-ventilated spot to dry completely before threshing.

Harvest & Storage

When to pick: NC State: ready to harvest once stems turn golden yellow and the seeds have become hard; cut stalks near the base with a sickle or scythe and bundle them together.

Storage

Hang bundles in a well-ventilated area to dry fully, then thresh the grain once completely dry; the grain is edible when cooked (NC State).

Diseases

Wheat rust (causal agent not yet confirmed)

moderate

Named only vaguely by RHS ("rust diseases"), no species identified -- generic entry created rather than guessing a pathogen.

Fusarium head blight (scab)

high

Fusarium graminearum

Named specifically by NC State as scab (Fusarium head blight), with an associated DON mycotoxin contamination risk in harvested grain.

Pests

Birds (grain)

moderate

various

Named by RHS as the main UK garden risk to grain.

Root-knot nematodes

low

Meloidogyne spp.

NC State names the southern root-knot nematode specifically; wheat is also noted not to host certain other nematodes.

Hessian fly

moderate

Mayetiola destructor

Named by NC State -- where this is a known local risk, delay planting until after the first fall frost.

Three-cornered alfalfa hopper

low

Spissistilus festinus

Named by NC State.

Wheat, Seed to Harvest

A single wheat ear

RHS notes wheat has been utilised for centuries as a cereal crop -- this close-up shows the tightly packed spikelets that make up the ear.

A field in production

RHS gives a mature height of 1-1.5m for wheat, tall enough to form a dense, wind-rippled field like this.

Plant structure detail

NC State notes wheat is most often grown by home gardeners as a fall-sown winter cover crop, valued for weed suppression and organic matter as much as for grain.

A cultivated field

NC State gives wheat a native range from Turkey through Iran to India -- now the world's most widely cultivated grain crop, grown as far afield as Saskatchewan.

Ready for harvest

NC State: wheat is ready to harvest once the stems turn golden yellow and the seeds have become hard.

Golden, ripe ears

At this stage, stalks are cut near the base, bundled, and hung to dry fully in a well-ventilated spot before threshing (NC State).

A field in wheat's native region

NC State traces wheat's origin to the region stretching from Turkey through Iran to India.

A field ready to ripen

RHS rates wheat H5, hardy in most of the UK even through severe winters -- autumn-sown crops like this overwinter reliably before ripening the following summer.

Bearded wheat ears

The long bristles (awns) extending from each ear are a distinctive feature of many wheat varieties.

1. North Carolina State University Extension (Plant Toolbox) - Triticum aestivum (Wheat, Winter Wheat)

   Light: full sun (6+ hours). Soil: clay/loam-silt/sand/high organic matter, pH neutral (6.0-8.0), good drainage, tolerates moist or occasionally dry conditions; best on moderately fertile soil not subject to flooding. Size: 2-4ft height, 6in-1ft width. Native range: Turkey through Iran to India, now worldwide. Propagation: seed, broadcast ~3in apart, 0.5in deep; soft spring wheat for spring sowing, hard winter wheat for fall (too-late winter planting leaves roots underdeveloped for winter survival). Pests: three-cornered alfalfa hopper, Hessian fly (plant after first fall frost where present). Diseases: southern root-knot nematode; scab (Fusarium head blight) with DON mycotoxin contamination risk. Edible use: grain edible when cooked; the world's most widely cultivated grain crop. Home garden use: most often grown as a fall-sown winter cover crop for vegetable gardens/orchards -- erosion prevention, weed suppression, organic matter incorporation; does not host certain nematodes. Harvest: ready when stems turn golden yellow and seeds are hard; cut stalks near the base with a sickle/scythe, bundle, hang in a well-ventilated area to dry fully, then thresh.

2. Royal Horticultural Society - Triticum aestivum (bread wheat)

   Hardiness H5 (hardy in most UK locations, even severe winters). Soil: chalk, clay, loam, sand, moist but well-drained, acid/alkaline/neutral pH. Sun/aspect: full sun, south/west-facing. Exposure: exposed or sheltered. Size: 1-1.5m height, 0.1-0.5m spread, 1 year to maturity. Propagation: seed, sown spring or autumn. No pruning required. Pests: may be susceptible to bird damage. Diseases: may be susceptible to rust diseases (unspecified). Edible use: cereal crop utilised for centuries in food production.
