Starting it indoors
- Fill a small pot or tray with seed compost
- Push the seeds in (2cm deep) - a couple per pot
- Water gently, then put them on a bright windowsill
- Keep the compost damp but not soggy - check it every day
- When they have 2 proper leaves, give each seedling its own pot
Sowing it outdoors
- Pull out any weeds and rake the top of your bed until it's crumbly, like cake crumbs
- Make a little line in the soil (2cm deep) with your finger or a stick
- Drop the seeds in, about 150cm apart each way
- Gently cover them with soil and pat it down
- Water with a watering can that has a sprinkler head
- Push in a label so you remember what's there
Planting it out
- Toughen them up ('hardening off'): put them outside in the day for a week, bring them in at night
- Dig a hole a bit bigger than the pot
- Tip the plant out gently, holding the leaves, not the stem
- Pop it in the hole, firm the soil around it, and water well
- Space the plants about 150cm apart each way
Top tips for growing pumpkins
- Plant on a mound of compost - they're very hungry.
Looking after pumpkins
- Week 2: Water well twice a week, at the bottom of the plant
- Week 10: Put a tile or piece of wood under each pumpkin so it doesn't rot
Soil and feeding
Rich, moist soil packed with goodness. These are hungry plants. Dig a hole (or make a mound) and fill it with manure or compost before planting, then feed every week or two once the fruit starts.
Pests and problems
- Slugs & snails: munch seedlings overnight, worst in wet weather
- Go on a slug hunt at dusk with a torch and move them far away
- Sink a jam jar into the soil with a little beer in it - slugs fall in
- Cut the bottom off a plastic bottle and pop it over each young plant, like a mini greenhouse
Harvesting and eating pumpkins
When the skin is hard and the stem cracks, cut it off with a bit of stem. Before the first frost!
How to eat them: Carve it, then roast the flesh for soup and the seeds with salt for a snack.
Storing pumpkins
Keeps 2-6 months once dried.
- Cut with a long bit of stalk - never carry it by the stalk!
- Dry it in the sun or a warm room for 1-2 weeks so the skin goes hard
- Keep somewhere cool and dry indoors
Cut into chunks, roast or boil until soft, cool and freeze. Great for soup.
Good varieties of pumpkins
- Jack O'Lantern: The Halloween pumpkin.
- Atlantic Giant: Grows the biggest pumpkins in the world - have a competition!
- Baby Bear: Small pumpkins - just right for pies and little hands.
Companion planting
Grows well with
- Sweetcorn: 'three sisters': big leaves shade out weeds under the corn
- Nasturtiums: nasturtiums bring in bees to pollinate pumpkin flowers
- Borage: bees for pollinating the flowers
- Phacelia: brings bees to pollinate
- Sunflowers: bring in bees to pollinate
Saving your own pumpkins seed
From a ripe fruit in autumn.
- Bees mix pollen between courgettes, squash and pumpkins, so saved seeds can grow odd-looking fruit - that's half the fun!
- Scoop the seeds from a fully ripe fruit (courgettes: leave one to grow into a huge marrow first)
- Wash them, then dry on a plate for 2 weeks
- Or roast them with a little salt - a tasty snack
- Seeds from 'F1' varieties (it says on the packet) don't grow the same - save from ordinary ones.
