Sowing Pumpkin: Propagating and Direct Sowing

Last updated: 27.12.2024

Reading time: 5 minutes

Pumpkins (Cucurbita) are plants that need warmth. In our latitudes, they are given a head start in growth and grown on the windowsill. This allows you to plant out strong young plants directly and benefit from their growth advantage with a rich harvest. However, direct sowing is possible depending on the region. In this article, you will learn how to pre-grow pumpkins or sow them directly. There are also instructions for planting out pumpkins.

When Are Pumpkins Sown?

So that you can plant out strong young plants in mid-May, you should start pre-cultivation about 2 to 4 weeks before the last frosts (mid/end of April), depending on the variety and environmental conditions.

Planting Pumpkin Seeds Correctly: How to Grow Them

From the middle/end of April, place one seed at a time , point downwards, about 2 to 3 cm/0.8 to 1.2 in deep in a small pot of potting compost. Pumpkin seeds are sown individually and not pricked out, as the roots of the pumpkin plant are fragile and do not tolerate pricking out well. It is therefore better to give each seed its own pot. At temperatures between 20 and 24 °C/68 and 75.2 °F, the seeds usually germinate within a week. A glass or foil over the pot can help to achieve the germination temperatures. After germination, cooler temperatures between 16 and 20 °C/60.8 and 68 °F are sufficient for the seedlings.

Pumpkin seedlings are already very robust and relatively large. Therefore, only one seedling grows per seed pot.

Planting Out Pumpkin Seedlings

Pumpkin plants need to be hardened off before planting out in order to acclimatize to the environmental conditions and the weather. You should also prepare your pumpkin bed, as pumpkins are heavy feeders and therefore have high nutrient requirements. You can find out How to Harden off Your Pumpkin Seedlings and Prepare Your Pumpkin Patch in this article.

Planting Pumpkin Plants Outdoors: How to Do It

Now you can plant your pumpkin seedlings outdoors. Place the plants deeper in the soil than before. The plant will then develop additional roots, which will give it more stability. This is important because pumpkin plants have very fragile roots. Now water the plant well and apply a layer of mulch. As pumpkins grow very vigorously, you should allow plenty of space for the giants: there should be around 1.5 - 2 m/1,6 - 2,2 m between the rows and between 0.5 - 1.6 m/0.5 - 1.7 m in the row. One pumpkin covers about two square meters of bed area.

To ensure that your pumpkins thrive, it is important to look after your pumpkin plants. You can find out How to Care for Pumpkin in this article.

Sowing Pumpkin Directly

Depending on the location, sowing outdoors can be started after the last night frosts. In our latitudes, this is possible after the ice saints (mid-May). Pumpkin seeds only germinate from a soil temperature of at least 10 to 15 °C/50 to 59 °F. The seedlings and young plants are at the top of the snails' menu and will be happy to have a snail fence or cold frame until they are strong enough to withstand the molluscs.

Gherkins recipe Ingredients: 4.2 liters white wine vinegar 0.2 liter white wine 4.2 liters of water 70 g sugar 35 g fine salt 3 kg cucumbers 3 tablespoons coarse salt For flavoring (to taste): Bay leaves garlic cloves Pink peppercorns Chili (optional) Preparation: Sterilize the jars: Preheat the oven to 120 °C. Sterilize empty preserving jars in the oven for 15-20 minutes. In the meantime, boil the lids in a pan of water for 15-20 minutes. Leave the jars and lids to cool before use. Preparing the cucumbers: Wash the cucumbers thoroughly, dry and cut into slices about 5-6 mm thick. Drain the water: Place the cucumber slices in a sieve, sprinkle with the 3 tablespoons of coarse salt and leave to rest for about an hour, stirring occasionally. This helps to remove excess water and makes them firm to the bite. Then rinse the cucumbers well under running water to remove the excess salt and spread them out on a clean kitchen towel to dry. Preparation of the liquid: In a large saucepan, combine the vinegar, white wine, water, sugar and fine salt and bring to the boil. Blanch the cucumbers: As soon as the liquid boils, blanch the cucumber slices for 1-2 minutes. Do not cook for too long, they should remain crunchy. Pour into jars: Drain the cucumbers and layer them neatly in the sterilized jars. Add bay leaves, garlic cloves, pink peppercorns and chili peppers to taste. Fill and seal: Fill the jars completely with the hot liquid so that the cucumbers are covered. Close the jars tightly and immediately turn upside down to create a vacuum. Leave to cool completely in this position. Even if the sweet and sour cucumbers are ready to eat immediately, it is best to wait at least a few weeks before opening them. The resting time allows the flavors to develop and combine perfectly.this recipe is from Lidia La.era.nuova
