Yes, it is definitely possible to plant pumpkins in Norway, and it’s becoming more common. While pumpkins are not a traditional part of Norwegian cuisine, the growing popularity of Halloween and an increasing interest in home gardening have led to a rise in pumpkin cultivation.
However, just like with grapes, successful pumpkin growing in Norway requires some strategy due to the cooler climate and shorter growing season. Here’s a breakdown of what you need to do:
1. Choose the Right Variety: The most important factor is to select a pumpkin variety with a short growing time. Look for varieties that mature in less than 100 days. Some good options for a Norwegian climate include:
- Hokkaido pumpkin: This is a very popular and reliable choice. They are relatively small, flavorful, and known for their hardiness.
- Butternut squash and spaghetti squash are also good options that can often be successfully grown.
- Smaller varieties like ‘Jack Be Little’ or ‘Casperita’ are also well-suited for a shorter season.
2. Give Them a Head Start: Due to the risk of late spring frosts, it’s highly recommended to start pumpkin seeds indoors.
- Start seeds indoors: Begin planting seeds in pots indoors in late April or early May.
- Provide warmth: Pumpkins are heat-loving plants. Keep the seeds in a warm place (around 25°C) to encourage germination. A heating mat or placing them on a radiator can work well.
- Harden off: Before planting them outside, you must “harden off” the seedlings. This means gradually acclimating them to outdoor conditions by placing them outside for short periods each day over a week or so.
3. Outdoor Planting and Care:
- Wait for the right time: Plant the seedlings outdoors only after all danger of frost has passed, usually in late May or early June, depending on your location in Norway.
- Sunny and sheltered location: Choose the warmest and sunniest spot in your garden. A sheltered area, perhaps against a south-facing wall, will provide extra warmth.
- Rich, well-drained soil: Pumpkins are heavy feeders and need nutrient-rich soil. Adding compost, manure, or other organic matter will help them thrive.
- Watering: Pumpkins need a lot of water, especially during warm, dry spells. Water regularly to ensure the soil stays moist.
- Protection: Using a fiber cloth or a small cloche (like a cut-off plastic bottle) over the young plants can protect them from cold and create a warmer microclimate in the beginning.
By following these tips, you can absolutely grow pumpkins in Norway and enjoy a rewarding harvest in late summer and early autumn.
