Key takeaways
- A 10 square metre patch of wheat gives roughly enough grain for four loaves
- Sow a proper bread wheat such as Maris Widgeon, not animal feed seed
- Autumn-sown wheat usually crops better than spring-sown in the UK
- Cut when the ears are golden and a grain feels firm, not milky, when you bite it
- Threshing and winnowing need little more than a bucket and a breezy day
- You'll need a grain mill or a strong food processor to make flour
Growing your own grain and baking a loaf from it is one of the most satisfying things you can do on a small plot. It’s very doable. It’s also a great lesson in why bread is so cheap! One garden bed won’t feed you for a year, but it will give you a few real loaves and a lot of fun along the way.
Here’s what to expect from a bed of wheat, which kinds bake well, and how to get from a patch of stalks to a bag of flour by hand.
How much grain can you grow in a garden?
Be realistic from the start. A 10 square metre patch of wheat gives roughly 2 to 3kg of grain. That’s enough flour for about four loaves. Farms get much more from the same space, with machines, fertiliser and modern varieties on their side.
A loaf needs about 500g of flour. So a single raised bed of about 3 square metres gives you one or two loaves a year. Feeding a family all year would take a small field, not a veg plot.
That’s no reason to skip it. Treat grain as a fun project rather than a staple. For crops that really fill the cupboard, our grow your own vegetables guide and crop rotation planner are the place to start.
Scatter wheat seed across a raked bed in October, like sowing a lawn, then rake it in. Autumn sowings usually do best.
Choosing the right grain to grow
What you sow decides whether you get bread flour or chicken food. Grow a proper bread wheat such as Maris Widgeon, not cheap seed sold for livestock or game cover. Bread wheats have what it takes to make dough rise.
Maris Widgeon is the classic pick for home bakers. It’s a tall old variety with good flavour and long straw that’s easy to cut and tie by hand.
Fancy something different? Einkorn and emmer are ancient wheats that cope with poor soil and make dense, nutty bread, though they crop less. Rye is the toughest grain for cold, wet northern plots and makes lovely dark bread. Quinoa is another seed crop worth a bed, and our quinoa growing guide covers it.
Skip modern short wheats bred for combine harvesters. Their short stalks are fiddly to cut and tie by hand, and the seed is hard to find in small packs. Heritage grain sellers and seed swaps are your best bet.
When and how to harvest
Getting the timing right makes all the difference. Cut when the whole plant has turned gold and a grain bitten between your teeth is firm and crunchy, not soft and milky. Too early and the grain shrivels as it dries. Too late and it drops onto the soil or sprouts in wet weather.
In most of the UK that’s late July or August. Wait for a dry spell. Cut the stems low with shears, a sickle or a serrated knife. Gather them into small bundles (sheaves) about a hand-span thick and tie each one. Stand them under cover, in a shed or porch, for one to two weeks until the straw is crisp.
Ripe wheat droops and turns gold all over. Firm and crunchy means cut now. Soft and milky means wait.
Threshing and winnowing by hand
Threshing just means knocking the grain off the stalks. For a small crop, stand the dried sheaves head down in a big, clean bucket and stamp or beat them. The grain falls to the bottom and the straw stays whole. For a bigger patch, lay the sheaves on a sheet and beat them with a stout stick. Pull out the straw and you’re left with grain mixed with papery bits called chaff.
Winnowing gets rid of the chaff. On a breezy day, pour the mix slowly from one bucket into another. The heavy grain drops straight down and the light chaff blows away. A fan does the same job indoors. Repeat two or three times until the grain runs clean. The dig for victory growers of wartime did exactly this, and it still works a treat.
Stamping dried sheaves in a deep bucket. Slow, dusty and oddly satisfying, and all you need is a bucket and a breeze.
Gardener’s tip: Thresh and winnow outside or in the shed, never in the kitchen. The dust gets everywhere, and a breezy afternoon does the winnowing for free.
Threshing methods compared
There’s more than one way to get grain off the straw. Pick the one that suits the size of your crop.
| Method | How it works | Best for | Effort |
|---|---|---|---|
| Bucket stamping | Stamp sheaves in a deep bucket | A single bed | Easy |
| Beating on a sheet | Beat sheaves with a stick | A bigger patch | Medium |
| Rubbing by hand | Rub ears between gloved palms | A few sheaves | Hard work |
| Fan winnowing | Pour grain past a fan | Any amount, wet days | Easy |
| Breeze winnowing | Pour grain between buckets outside | Any amount, dry days | Easy |
Milling grain into flour
Clean grain isn’t flour yet, and this is where lots of first tries come unstuck. You need a grain mill or a strong machine. An ordinary kitchen blender won’t do it.
A hand mill clamps onto the worktop and grinds grain into wholemeal flour in minutes, with a dial to set how fine. Electric grain mills are quicker. For the odd small batch, a powerful food processor or spice grinder copes, but the flour comes out coarse and warm, so let it cool before baking. Sieve out the bigger bran flakes if you’d like a lighter loaf.
Keep flour in an airtight jar and use it within a few weeks. Home-milled wholemeal goes stale faster than shop flour, so grind little and often.
A clamp-on hand mill turns clean grain into wholemeal flour in minutes. A blender just can’t crack the grain properly.
Storing grain and using your flour
Whole grain keeps far longer than flour, so store most of your crop unground. Kept dry and cool in a sealed container, it stays good for many months. That’s why people used to mill fresh as they needed it.
Make sure the grain is properly dry before it goes into store. Put it in airtight jars or food-grade tubs somewhere cool and dark. Check it after a couple of weeks. Any dampness or tiny creepy-crawlies means it went in too damp.
The reward: a dense, nutty wholemeal loaf from your own wheat. Only a handful of loaves from a bed, but every one is special.
Frequently asked questions
Can you grow wheat in a UK garden?
Yes, wheat grows happily in a garden bed or allotment. Scatter it like grass seed in autumn or spring and it ripens to golden ears by late summer. The tricky bits are the small harvest and the hand work of threshing. A 10 square metre patch gives roughly enough grain for four loaves.
How much wheat do you need to grow for a loaf of bread?
Roughly 2 to 3 square metres of wheat per loaf. A loaf needs about 500g of flour, which takes a bit more than that in grain. So a typical raised bed gives one or two loaves. Feeding a family all year would need a small field.
How do you thresh wheat by hand?
Stamp or beat the dried ears to knock the grain loose. Put the sheaves head down in a big bucket and stamp on them, or flail them on a sheet. Then pour the mix between two buckets in a breeze so the light chaff blows away. Dry the cut crop under cover for a week or two first.
Can you mill your own flour at home?
Yes, but you need the right tool. A hand or electric grain mill turns clean grain into flour in minutes. A powerful food processor or spice grinder copes with small amounts but gives coarser flour. An ordinary blender struggles. Sieve out the bigger bran flakes for a lighter loaf.
When do you harvest home-grown wheat?
When the whole plant is golden and the ears droop. Bite a grain: ripe grain is firm and crunchy, not soft or milky. In most of the UK that’s late July or August. Cut with shears or a sickle, tie into small bundles, and dry them under cover before threshing.
