This guide forms part of our month-by-month allotment planting calendar.
February sits in an awkward but important place in the allotment calendar. It’s still winter, but the growing season is no longer hypothetical. Daylight is increasing, temperatures are slowly stabilising, and decisions made now start to shape the months ahead.
This is not a month for enthusiasm-led planting. February rewards growers who think in sequences rather than individual crops.
This guide explains what you can realistically sow in February, what should stay under cover, and why having a simple plan now prevents problems later in the season.
Understanding February Conditions on an Allotment
February soil is still cold and often wet. Frost, heavy rain and exposed conditions remain common across much of the UK, especially on open or north-facing plots.
What has changed is light. The longer days make a noticeable difference to seedlings raised under cover. Compared to January, plants started in February are far less likely to become weak or leggy, provided they are not rushed.
This makes February a sensible point to begin sowing selectively under cover, while remaining cautious outdoors.
February planting decisions aren’t just about the calendar — they’re heavily influenced by short-term weather.
A mild spell can make late-month sowing viable on sheltered plots, while a sudden cold snap or frost can set plants back weeks. This is why relying on fixed dates alone often causes problems.
Many growers now check local forecasts and frost warnings before committing to sowing, especially in February. Seeing upcoming conditions alongside your planting plan makes it much easier to decide whether to go ahead or wait.

What You Can Sow Under Cover in February
February is the month where controlled indoor sowing starts to pay off.
Broad beans are still a strong option if you didn’t sow earlier. Plants raised now establish well once planted out and tend to grow evenly through spring.
Onions can continue to be sown from seed, producing sturdy plants that are ready to go out once conditions improve.
Early brassicas such as cabbage, cauliflower and kale can also be started under cover, provided you have enough space to grow them on steadily rather than forcing early growth.
Leeks are another reliable February sowing. Their long growing season benefits from an early start, and seedlings raised now are generally easy to manage.
At this stage, it helps to think about where these crops will eventually sit on your plot, not just whether they can be started now.
What You Can Sow Outdoors (With Care)
Outdoor sowing in February is possible, but only in the right conditions.
On well-drained, sheltered plots, some gardeners sow broad beans or hardy peas towards the end of the month. Success varies year to year and depends heavily on weather and soil condition.
If the ground is cold, compacted or waterlogged, waiting is usually the better decision.
February is rarely about pushing boundaries outdoors. It’s about preparing for a smoother spring.
What You Should Still Avoid Planting
Despite the longer days, many crops are better left until later.
Carrots, beetroot, beans, sweetcorn and most salad crops will struggle if sown too early outdoors. Potatoes should also wait, even if seed potatoes are already available.
Starting tender crops too early under cover often causes more problems than it solves, as plants quickly outgrow available space and become difficult to manage.
Knowing what not to plant is just as important as knowing what you can start.
How February Fits Into Your Allotment Plan
February is where planning starts to matter more than activity.
The goal isn’t to fill trays or make the plot look busy. It’s to establish a small number of strong plants that fit into a wider plan for the season.
This is the point where decisions about crop rotation, spacing and succession planting begin to affect outcomes. Without a plan, it’s easy to sow things that later compete for space or end up in the wrong place.
Many growers find it useful at this stage to sketch out their plot for the year so February sowings naturally feed into what comes next.
A Common February Mistake
The most common mistake in February is confusing what’s possible with what’s necessary.
Just because a crop can be sown now doesn’t mean it should be. Overcrowded trays, rushed planting and poor spacing often undo the benefits of starting early.
Steady progress beats early volume every time.
Plan February Properly
February is the first month where planting starts to feel purposeful again. Used well, it gives you a calm head start without creating pressure later in the season.
If you want to see how February sowings fit into the rest of your year, you can map them out using the allotment planner. It helps you visualise where crops will go, avoid clashes later, and keep sowing decisions grounded in space and timing rather than guesswork.
