About Naked Pumpkins:

I had often wondered how pumpkin seeds are prepared – they are available in every health food shop and supermarket and I couldn’t figure out how they could be cracked open.

So – in Styria in Southern Austria – a chance mutation over 100 years ago produced shell-less seeds. They have grown them ever since to make pumpkin seed oil and for its edible seeds for baking and snacks. The variety is called Gleisdorfer Pumpkin. They are easy to grow, just like any other squash or pumpkin. In Styria they also produce a famous pumpkin seed oil from this variety.

Soil and site:

Pumpkin, Naked – Gleisdorfer Oelkuerbis needs a fertile, free-draining soil that can hold plenty of moisture. A generous application of well-decomposed compost is beneficial (about 1 bucket per square meter).
They also need a very sheltered place in the garden or better even grown in a polytunnel or greenhouse.


Pumpkins belong to the cucurbit family. This family is not prone to any soil borne pests and diseases, so there is no need to stick to a strict rotation. In fact they could be grown in the same place every year.

Plant care:

From each plant you will  get between 6 to 10 fruits.


Harvest Pumpkin, Naked – Gleisdorfer Oelkuerbis in October and harvest the seeds.  The seeds can be eaten fresh and also dried.  The flesh can also be eaten but is quite bland tasting.

Potential problems:

Apart from their sensitivity to cold and windy weather there are no specific pests or diseases that affect pumpkins. Slugs, however, like the newly planted pumpkins, so you need to protect them.

How much to grow:

Pumpkins are only suitable for large gardens. Everybody underestimates the space they require. Unless you have a large garden only one to two plants are sufficient. At least you’ll have some fun at Halloween.
