After the carving: what to do with your Halloween pumpkin

Eat the flesh on carving night, roast the seeds, compost the shell without the wax. Why it shouldn't go out for the hedgehogs, and why its seed may not give you the same pumpkin next year.

Most Halloween pumpkins are bought to be looked at for one night and then thrown away. Love Food Hate Waste, the campaign run by the charity WRAP, puts it at 12.8 million pumpkins bought for decoration each Halloween that are likely to go uneaten.

None of it needs to be wasted. You can eat the inside, compost the rest, and get a few ideas for next year's crop out of it. One popular idea is worth dropping, though: leaving the old pumpkin out "for the hedgehogs".

01At a glance

  • Eat it: scoop and cook the flesh on carving day, before it has sat by a candle.
  • Seeds: simmer, then roast. They're the best bit of a carving pumpkin.
  • Compost: chop it up. Remove candles and wax first. Bin any pumpkin with paint or glitter on it.
  • Wildlife: don't leave pumpkins out for hedgehogs or dump them in woods.
  • Pets: throw the pumpkin out before it goes mouldy.
  • Next year: sow indoors in mid to late April, says the RHS.

02Carving pumpkins are food, just not great food

The RHS says any pumpkin can be carved. It names varieties such as 'Jack O'Lantern', 'Racer' and 'Prizewinner' for carving, and keeps a separate list for eating, including 'Crown Prince', 'Uchiki Kuri' and 'Queensland Blue'. Most pumpkins are varieties of Cucurbita pepo or Cucurbita maxima, according to the RHS.

Carving types are edible, but don't expect much. Hubbub, the charity behind the #PumpkinRescue campaign, is honest about this: it has eaten some good carving pumpkins and some that "taste of nothing", and it says they are often watery and fibrous. So use them in dishes that bring their own flavour, like soup and curry.

03Eating it

  1. Save the flesh as you carve. Cook it that day, not after the lantern has stood around. Hubbub warns that once a carved pumpkin starts to droop, it is no longer safe to eat.
  2. Or freeze it. Hubbub says raw or steamed flesh keeps a few days in the fridge, or you can blanch or steam it and freeze it.
  3. Roast the seeds. Wash off the stringy pulp. Hubbub's method is to simmer the seeds in salted water for 10 minutes, then bake them in a hot oven until brown.
  4. Keep uncarved pumpkins for later. The RHS says fully ripe, cured pumpkins should be stored at 10–15°C somewhere airy, not touching each other. They keep for at least three months that way.

04Composting it

  1. Take out the candle and every bit of wax. Vale of White Horse asks for this before a pumpkin goes in the food bin, and Warwickshire asks the same before it goes in a home compost bin.
  2. Bin, don't compost, painted or glittered pumpkins. Warwickshire's advice is to throw away any pumpkin with glitter or paint on it.
  3. Chop it into pieces. Smaller pieces rot faster in a home compost bin, and fit better in a council food caddy. See our guide to making garden compost.
  4. Use a lidded bin if you have a dog. Mouldy food on an open heap is exactly what you are trying to keep away from it (see below).

05Hedgehogs and the countryside

People put old pumpkins out for hedgehogs or leave them in woods, thinking it helps. The charities say don't, but disagree on how much harm it does.

  • British Hedgehog Preservation Society. Quoted by Countryfile: "We think too much would upset hedgehog tummies."
  • Northumberland Wildlife Trust. Firmer. It calls pumpkins a natural laxative that can cause hedgehogs "serious diarrhoea and dehydration". It adds that dumped pumpkins attract rats and smother wild plants.
  • Woodland Trust. It calls the idea that pumpkins in woods help wildlife a myth, and says dumped pumpkins damage woodland soils, plants and fungi. It does say small amounts in gardens can be fine.
  • Scottish SPCA. Its wildlife rescue centre has said there isn't much data showing pumpkins upset animals' guts, but that it can't be ruled out.

So the evidence is thin, but none of these charities tells you to put a pumpkin out for hedgehogs. Hedgehogs eat beetles, worms and other invertebrates, and they are fattening up for winter now. If you want to help, Hedgehog Street suggests meat-based wet cat or dog food, or dry cat biscuits, with a dish of water. Never milk. Our hedgehog profile has more. The pumpkin goes in the compost bin.

06Mouldy pumpkins and pets

Once cut, a pumpkin can go soft and mouldy quickly in a damp autumn. The ASPCA warns that pumpkins, especially once cut open, can grow mould that could give a dog tremors or seizures. The PDSA's advice is the same: get rid of pumpkins before pets can eat mouldy ones. The ASPCA doesn't list pumpkin itself either way, so our pumpkin profile flags the gap rather than calling it safe. The PDSA also asks you to keep lit candles and carving tools out of pets' reach.

If your pet has eaten a mouldy pumpkin, take it away, don't try to make them sick, and ring your vet or the Animal PoisonLine on 01202 509000. It is a paid 24-hour service (£35–£45 a call).

07Saving the seed, honestly

You can grow next year's lantern from this year's seed, but don't expect the same pumpkin.

  • F1 hybrids don't come true. The RHS says seed saved from F1 hybrid plants will not produce plants true to the parent type. Some carving varieties are F1 hybrids, such as 'Racer F1' on the RHS list. A shop-bought pumpkin rarely tells you which variety it is.
  • Pumpkins cross easily. The RHS adds that even open-pollinated seed won't always come true, especially with a related plant nearby. Pumpkins, courgettes and many squashes are pollinated by insects. Seed Savers Exchange recommends hand-pollinating and taping the flowers shut to keep a variety pure.

Sow a few saved seeds for fun and see what you get. For a pumpkin you can rely on, buy named seed.

08Growing your own next year

The RHS timings:

  1. Sow indoors in mid to late April. One seed per 7.5cm pot, kept at 18–21°C.
  2. Or sow outdoors in late May or early June, after the last frost.
  3. Harden off and plant out after the last frost. Bush types need 90cm between plants and trailing types 1.5m.
  4. Harvest before the first frost, with at least 10cm of stem, and cure the fruit in the sun for 7–10 days before storing.

Our pumpkin profile covers feeding, pollination and stopping fruit rotting on wet soil.

Save your money
Buy a smaller pumpkin. The RHS calls small to medium fruit more convenient for eating, and they cost less.
Don't buy a second pumpkin for soup. The flesh you scoop out on carving night is the soup.
Skip the seed packet for a year, if you're curious. Saved seed is free. Just treat the result as a surprise.
Carve late. Cut flesh starts to spoil, so carving on the 30th or 31st gives you a lantern that lasts the night and a pumpkin you can still eat.
