How to Properly Store Watermelon Seeds for Future Use

Watermelon is one of the most refreshing fruits to have on hot summer days. Its juicy, sweet and refreshing taste make it a favorite for many. However, what about the seeds? Have you ever thought of storing them in case you want to plant them later? In this blog post, we’ll discuss how to store watermelon seeds properly.

Why Store Watermelon Seeds?

There are several reasons why you may want to save your watermelon seeds instead of disposing of them immediately after consuming the fruit:

Growing Your Own Watermelons

One reason you may want to keep your watermelon seeds is if you plan on growing your own watermelons in the future. When stored correctly, these seeds can last up to four years before they lose their viability. Thus, by saving some viable seeds from each batch of watermelons that you consume, you can have an endless supply of fresh home-grown watermelons.

Preserving Biodiversity

Another important reason for preserving and storing your own seed is biodiversity conservation as commercial seed varieties are limited and there’s hardly any diversity available at supermarkets or greengrocers.

Preparing The Seeds For Storage

Spread them out on a drying rack or an open tray lined with parchment/baking paper (Don’t use newspaper as the printing ink may have chemicals that can harm germ viability). Leave those little guys in warm, dry locations safe from exposure to direct sunlight.

Make sure you turn seeds over every day or so for several days until they become hard and brittle enough without direct heat sources like ovens this could affect their germination potential.

Storing The Seeds

Label each container clearly by name of variety/species & date harvested; which is useful information when prioritising seedlings later on before planting.”
