Pumpkin Seeds

How To Grow

Sowing Seeds Indoors

  • Can be sown indoors using small containers (e.g. empty tin (being careful if sharp edges on tin), a yoghurt/plastic container or similar with holes punched in the bottom for drainage) in rich soil (e.g. compost).

  • Ensure soil drains well – putting a few stones at the bottom of the container, before placing the soil on top of it, will assist drainage.

  • Fill container with compost, make hole approx 2cm deep, water the soil once the hole has been made, place one seed in on its side and cover with soil, gently pressing on soil again to firm it down

  • Keep containers on a sunny window sill (need warmth to germinate)


  • After approx. 3 – 4 weeks, transplant seedlings.

  • Harden plants for 7 days or so before transplanting –  bring them outdoors each day for a few hours.

  • Soil to transplant into needs to be well drained, fertile soil (e.g. compost) that gets full sunshine and is protected from the wind. Pumpkin is a hungry plant. 

  • Position plants 2 metres apart when planting.

  • Dig a hole in the soil approx. 5cm deeper than the pot height that the seedling has been growing in, and water if soil is dry. 

  • Carefully loosen the pumpkin plant from the pot and place it in the hole, filling around the plant with soil and gently pressing on it.

  • Keep the soil weed free, ensuring you don’t damage plant in the process.

  • Ensure soil remains moist, don’t allow to dry out. 

  • To encourage growth and deter pests/slugs, feed every 4 – 6 weeks or so with organic fertiliser (e.g. dried milled seaweed fertiliser, sachets available on sow.ie).


Growing Time: 

  • 4 months



  • When leaves die back

  • Harvest fruit still attached to the stalk


Tip: Place a stone/brick under each fruit as it grows so that it’s not touching soil (it might rot if it is touching wet soil consistently)!
