How to Avoid the Hungry Gap in Your Vegetable Garden

The hungry gap is the stretch of early spring when the vegetable plot has little or nothing ready to eat, just as the winter stores are running down. The growing charity Garden Organic describes it plainly: early spring has little veg or fruit available, and winter is a challenge for many crops¹. The gap usually falls from April into June, before the first new-season crops are heavy enough to pick.

You close it by planning backwards. Sow and plant in late summer and autumn so that crops stand through the winter and start producing in spring: kale sown as late as August will keep you in leaves all through the winter and the spring hungry gap, and spring cabbage sown in mid-August is ready the following spring¹. Then store the autumn harvest carefully so roots, potatoes, onions and garlic carry you across the lean weeks¹.

The work is mostly in the calendar, not in special kit. Keep sowing, even in mid-summer, because that is the key to having veg through the autumn and winter¹. Choose several varieties of the same vegetable that mature at different times, planting early, midseason and late varieties to stagger the harvest². Plan the sowing so the crops are ready when you need them, the same discipline schools are advised to use so harvests land in term time³.

What the hungry gap is and when it falls

The gap is a calendar problem rather than a soil problem. Through late winter the plot is either bare, waterlogged or holding crops that are not yet ready, and the stored harvest from last year is thinning out. Garden Organic's summary is that early spring has little veg or fruit available, and that winter is a challenge for many crops¹. The gap therefore runs from roughly April, when the last roots and greens are used up, to June, when the new season's crops begin to arrive.

June is the turning point. The Royal Horticultural Society's month-by-month guide lists runner beans, peas, garlic, early potatoes and strawberries as crops to harvest in June⁵. May is still thin by comparison, with broad beans, salad leaves and spinach the main harvest⁵. That is the shape of the year you are planning around: a light May, a fuller June.

Two things make the gap worse than it needs to be. The first is a glut the previous summer that goes unharvested or unprocessed, so nothing is carried forward. Harvesting veg early can prevent a mid-season glut, and small produce is perfectly good: new potatoes the size of golf balls are delicious, as are slim small broad beans which can be eaten pod and all¹. The second is a plan that assumes everything will be ready at once. Choosing several varieties of the same vegetable that mature at different times, with early, midseason and late plantings, spreads the harvest across the weeks when you need it⁴.

The gap is not the same everywhere. Gardeners with a short growing season, further north, get better results from mini-veg varieties, which are ready to harvest sooner than large size varieties and crop well at close spacing¹. If your season is short, plan around quick, small crops rather than large, slow ones.

Crops that fill the gap from April to June

The crops that carry you across the gap fall into three groups: things standing in the ground through winter, things sown in late summer for spring, and quick crops sown in spring itself. Brassicas do most of the heavy lifting. Kale, cabbage, turnips and broccoli will all grow over the winter months¹, and kale sown as late as August keeps you in leaves all through the winter and the spring hungry gap¹.

Asparagus is the classic gap filler if you can give it a permanent spot: it takes several years before a good harvest, but it is a great hungry gap filler from late April to early June¹. Purple sprouting broccoli is one of several broccoli varieties, and broccoli is in season from June to November⁶. One summer purple sprouting variety is described by its distributor as producing tender purple spears from July to November⁷, so check the harvest window of the variety you buy rather than assuming all purple sprouting is a spring crop.

For the weeks before the spring crops are ready, quick salad crops bridge the gap. Lettuce, mustard seeds, oriental salad and rocket will provide you with tasty leaves in just a few weeks and can be grown indoors or on a windowsill⁸. Most brassicas such as chard, cress and spinach are tasty and easy to grow as microgreens⁸. These are small harvests, but they keep something fresh on the plate while the main crops come on.

Sowing and planting in late summer and autumn for a spring harvest

The single most useful habit is to keep sowing when the plot already looks full. Garden Organic puts it directly: the key to success in having veg through the autumn and winter is to continue to sow, even in mid-summer¹. Sowing in July and August feels late, but it is exactly what stocks the gap.

The RHS summer-term guide lists kale, leeks and onion among the crops to sow and plant in July⁵. Garden Organic gives late August for endive and mid-August for spring cabbage¹. Kale can go in as late as August and still crop through winter and spring¹. Work backwards from the month you want to eat, not forwards from the first warm day.

Under cover, the calendar stretches. Hydroponic crops are grown under cover, either in a glasshouse or polytunnel, and the growing season can be extended with extra heat and light⁹. In a greenhouse bed, outdoor crops such as potatoes and peas can be grown to bring them forward several weeks, and by July and August the space is clear for winter salads and veg¹. If you have a polytunnel or greenhouse, see Polytunnels and Greenhouses: Growing Under Cover All Year for how to use the space across the seasons.

Rotation matters too. Deep-rooted plants such as carrots and parsnips open up the soil for more shallow-rooted plants such as salads the following year¹⁰, so follow a root crop with a salad crop where you can. Onions, garlic, shallots and leeks form the allium family and are grouped together in planning¹⁰. For the wider principles of planning a plot, see Growing Your Own Vegetables: Where to Start and Sowing Seeds Indoors and Outdoors: Timing, Depth and Germination.

Stored crops: making the autumn harvest last into spring

Storing is the other half of the plan. Root veg such as carrots and beetroot can be harvested in late autumn and stored carefully for several months, as can potatoes, onions and garlic¹. The purpose is exactly the one Garden Organic gives: storing produce either in times of glut, or to tide you through the winter⁴. A good autumn store is what you eat in April.

Harvest at the right moment. Harvest onions and shallots when all the leaves have fallen over naturally, and dig out garlic when just the first four or six leaves turn yellow¹¹. Parsnips taste better when harvested after the first frost, and they will store¹. Lift roots in dry conditions where you can, and discard any that are damaged before they go into store.

How long a crop takes from sowing to harvest tells you what can realistically be stored and when. The RHS crop planner divides crops into groups by the time they take:

• Medium-term crops: sown or planted in one term to harvest in the next, 14 to 25 weeks (three to six months) later³.
• Slow-growing or long-season crops: sown or planted in one term to harvest in the next term or even the following term³.

Anything in the slow group is a candidate for the store rather than the plate, because it will not be ready until well after the gap has passed. For the detail of clamping, drying and checking stored roots and onions, see Storing the Harvest: Roots, Onions, Squashes and Apples.

Where the plan can fail: hard winters, pests and bolting

The gap plan fails in three predictable ways, and each has a response.

Hard winters. Cold, wet and frozen ground slows or kills overwintering crops, and the weather can also cut you off from the plot. The Met Office's winter advice is to make alternative plans¹², and the same applies to the garden: assume some overwintered crops will be lost and sow a little more than you need. If bad weather is forecast, plan ahead and check that you have enough food in case it is harder to leave the house¹³. Keep a store of long-lasting cupboard essentials such as tinned vegetables, beans, pulses, soup and pasta¹⁴ as a backstop, so a failed crop is a disappointment rather than a gap in the kitchen.

Pests and disease. Overwintering brassicas are exposed for months, and a crop that survives the cold can still be lost to pests. Plan for it: see Vegetable Pests and Diseases: Prevention and Control for prevention and control, and How to Protect Carrots from Carrot Fly where roots are in the ground over winter.

Bolting. Crops that run to seed stop producing leaves. Lettuces, spinach and Swiss chard may have gone to seed, meaning the usually leafy vegetables have formed flowers on the end of a long stalk and then seeds¹⁵. Once that happens the leaf harvest is over, though the seed can be collected, dried, sorted and saved to sow next year¹⁵. If you have space, leave one leek plant, an onion plant and maybe even a carrot and parsnip plant to over-winter; the next year they will flower and you can save their seeds¹⁵. For more on this, see How to Save Seed from Your Own Vegetables.

A fourth risk is simply running out of time and space. Check the crop planner to see whether your chosen vegetables can be sown and harvested in the time and season available¹⁶. If the answer is no, choose a quicker variety rather than hoping.

Small gardens, containers and growing under cover

You do not need a full plot to eat through the gap. A container garden can work for people short of space, lacking soil or in temporary accommodation¹⁷. Salad leaves are the easiest start: fill your chosen container with a peat-free compost, and if you have no flower pots or seed trays, a yogurt pot or fruit punnet with holes punched in the bottom works perfectly⁸. Grow them indoors or on a windowsill for the earliest leaves⁸.

Mini-veg varieties suit small spaces particularly well. They are ready to harvest sooner than a large size variety, which is particularly helpful if you have a short growing season further north, and they crop well at close spacing¹. For more on making the most of limited room, see How to Start Growing Food in a Small Space and How to Grow Microgreens Indoors.

Under cover, the options widen. A glasshouse or polytunnel lets you extend the season with extra heat and light⁹, and greenhouse beds can bring outdoor crops such as potatoes and peas forward several weeks before being cleared for winter salads and veg by July and August¹. If you are deciding between structures, see Polytunnel or Greenhouse?.

Freezing and preserving the surplus

A glut is only useful if you hold on to it. Freezing is the simplest route for many households, and the same freezer that holds the summer surplus carries you towards spring. Keep it stocked with essentials such as bread, and keep long-life milk in the cupboard¹⁸. Food safety rules still apply: eat leftovers within 2 days¹⁹.

Frozen produce has a second use in the garden year. A pack of frozen vegetables makes a good cold compress: use a pack of frozen vegetables or partly fill a plastic bag using small ice cubes or crushed ice, and wrap the bag in a dry cloth²⁰. That is a small household tip rather than a preserving method, but it is worth knowing when the freezer is full.

For the detail of preparing and blanching before freezing, see Freezing Home-Grown Fruit and Vegetables and Why Blanch Vegetables Before Freezing?. If you want to preserve without relying on the freezer, see Fermenting Vegetables at Home: Sauerkraut, Kimchi and Brines and the Home Preserving Equipment Checklist.

Where to get help and further reading

The hungry gap is a planning problem, and the best help is a calendar and a crop planner. The RHS vegetable crop planner sets out what can be sown and harvested in the time and season available¹⁶, and the RHS month-by-month guides list what to sow, plant and harvest each month⁵. Garden Organic's guide to vegetables all year round is the clearest single account of the gap and how to close it¹.
