If you’ve never tried planting pumpkin seeds, remember that even the seeds from grocery store pumpkins will germinate! However, because pumpkins and squashes cross-pollinate so quickly, you may not get exactly what you expect. As a result, the store pumpkin is most likely a hybrid of the parent kinds. This hybrid may or may not be edible.

Pumpkins are fruits, not vegetables, and they belong to the same “family” as melons, cucumbers, squashes, and courgettes. Anything with seeds is often categorized as a fruit. They come from the family Cucurbitaceae, which has adapted over time to survive in harsh environments. In this article, we’ll deeply explain the preparation of pumpkin seeds.

The seeds should be kept dry and cool in a paper envelope. A few individuals store the envelopes in the refrigerator in an airtight container.

Q3. How do you make pumpkin seeds grow faster?

As previously stated, pumpkins are heavy feeders, so add manure or compost to the soil and mix it with water. Using nitrogen-rich fertilizers in the early stages of growth will aid in germination and accelerate the growth process considerably faster than other formulations.

Q4. Do pumpkin seeds need direct sunlight?

Select a location that gets at least six hours of direct sunlight per day, and amend the soil beforehand with a generous amount of compost or well-rotted manure. Depending on the cultivar, planting distances might vary from 90 cm to 3 m, so make sure to check the seed packet.

Q5. Do pumpkin seeds expire?
