Brussels sprouts are usually harvested from autumn through winter in the UK, although timing depends on the variety and sowing date. Start picking when the lower sprouts are firm, tightly formed and a useful size, then work upwards as the later sprouts develop.
Brussels Sprout Harvest Quick Guide
| Typical harvest | Autumn to late winter |

When Are Brussels Sprouts Ready to Pick?
Judge readiness by the condition of the sprouts rather than the calendar. They should feel firm when gently squeezed, have tightly closed leaves and look healthy and well developed. The lowest sprouts are usually ready first, while those further up the stem remain smaller.
Begin harvesting at the base and leave the upper sprouts to grow on. Pick mature sprouts before they start opening, becoming loose or turning yellow. A smaller sprout can still be ready if it is firm, compact and has reached a useful size.
How to Pick Brussels Sprouts
Start at the bottom of the stem, where the earliest sprouts usually mature. Hold each firm sprout and twist it downwards until it comes away, or cut it from the stalk with a clean, sharp knife.
Work upwards over several picking sessions, leaving small, tightly closed sprouts in place until they develop further. Check the plant regularly during the harvest season, particularly in mild autumn and winter weather.
Brussels sprouts are normally harvested gradually rather than all at once. Avoid stripping the entire plant unless most of the sprouts have matured together or you are clearing the bed. Picking from the bottom upwards gives the upper sprouts more time to develop.
How Many Times Can You Harvest Brussels Sprouts?
You can usually pick Brussels sprouts several times from one plant. Start with the mature lower sprouts and return regularly as those higher up the stem become ready.
How long harvesting continues depends on the variety, sowing date, weather and how evenly the sprouts mature. Harvest whenever enough are ready for a meal rather than removing a fixed number each time.
Should You Wait Until After Frost to Harvest Brussels Sprouts?
Cold weather and frost can make Brussels sprouts taste sweeter, but you do not need to wait for frost before harvesting. Firm, tightly closed and well-developed sprouts can be picked whenever they are ready.
Do not leave mature sprouts indefinitely while waiting for frost. They may open, loosen or deteriorate, especially in wet or mild weather. Harvest sound sprouts as they mature, whether or not frost has occurred.
Can You Harvest the Whole Brussels Sprout Stalk?
Most home growers harvest individual sprouts gradually from the bottom upwards. However, if most of the sprouts have matured together, you can cut the whole stalk and remove the sprouts as needed.
Cut the stem close to ground level with a sharp knife, taking care because the stalk can be tough. Whole-stalk harvesting is useful when clearing a bed or bringing the crop indoors, but it is best done once most of the sprouts are ready.
Harvesting Brussels Sprout Tops
The leafy growing point at the top of a Brussels sprout plant is edible and can be harvested towards the end of the main crop. Cut off the tender top and cook it like other brassica greens.
Avoid removing the top too early if you still want the upper sprouts to develop. Once most sprouts have reached a useful size, cutting the growing point gives you an additional harvest from the plant.
What If Brussels Sprouts Are Loose or Open?
Loose or blown Brussels sprouts are still edible, although they may have a less compact texture. Slice or shred them before cooking, or use them in soups, stews and stir-fries. Once a sprout has opened, it will not tighten back up on the plant, so harvest it rather than leaving it to deteriorate.
For the causes of loose sprouts and ways to reduce the problem in future crops, see the How to Grow Brussels Sprouts in the UK guide.
Brussels Sprout Harvest FAQs
Usually from autumn through winter in the UK. Start with firm, tightly closed lower sprouts and continue upwards as later sprouts mature. For more advice on seasonal growing and harvesting, see this Winter Growing Guide.
Ready sprouts feel firm and look tightly closed. Pick them before they become loose or open.
Usually several times. Harvest mature lower sprouts first and return as those higher up the stem become ready.
Yes. They remain edible, but their texture may be less compact, so pick them once they are firm and ready.
They do not normally produce a full second crop, but the leafy top can still be eaten towards the end of the season.
