Pumpkins: How to grow

Pumpkins are simple to grow and the fruits store well in a cool dry conditions. Great for growing with kids and delicious roasted or used for making soups. They’re full of nutrients too; did you know pumpkin seeds are a super-food? This has made this easy to grow plant very popular with gardeners. 

Step 1

Pumpkins: How to grow - Step 1

How to grow: Pumpkins have large seeds that need soaking overnight before you sow. If you want to harvest early in July, then sow indoors from April and put outside in June. They do best when planted directly in the ground though so for regular harvesting (July – October) sow outdoors in May or June once the soil has warmed up. They should take about a week to germinate. They prefer a sunny sheltered position.

Indoor sowing: Place in a 9cm pot filled with Westland seed compost on its side. Once germinated it should produce two or three leaves and then it’ll be ready to harden off during the day outside and brought in at night.

Outdoor sowing: Prepare the soil and sow 3 seeds together at 3cm depth, one metre apart. They need space! Handy tip: dig a medium size pot into the soil next to each plant and use this to water the plant. This will ensure the plants don’t rot but the roots get enough water.

Growing: As they grow remove the weaker plants to leave one strong plant. You’ll need to protect them from slugs and snails so consider putting slug pellets down like Growing Success Slug Killer Advanced which contains a natural ingredient so can be used with edible plants.

If you’ve chosen trailing varieties you’ll need to pinch out the tips of the main stems when they reach about 2 feet in height to promote side shoots and flowering – this is what produces the fruit. Pumpkins need to be kept well-watered but avoid getting the leaves wet. Add a mulch like Gro-Sure Farmyard Manure and start feeding with Gro-Sure Tomato food once the fruit starts to swell every 1-2 weeks.

Harvesting: Pumpkins are generally ready to harvest come September. To help them ripen up cut back all the green foliage a few weeks before you intend to harvest them. When ripe pumpkins display their familiar orange colour but you can check for ripeness by giving them a tap – they should sound hollow or checking the stem and skin which should have hardened. When picking use a sharp knife rather than breaking off by hand to minimise diseases and prevent skin rash.
