When to Plant Cantaloupe Seeds

Surely, we wonder when to plant cantaloupe seeds, well the best time to plant cantaloupe seeds is in late winter and early spring.

We take a piece of aluminum foil, larger than the size of the paper napkin, we spread it on the table, and, inside it, we spread the moistened napkin. On it, we spread our cantaloupe seeds, keeping them separated from each other so that when they germinate their roots do not end up entangled with each other. Close the napkin in half, covering the cantaloupe seeds and pressing down so that the entire surface of the napkin is in contact with the seeds and keeps them moist.

Finally, fold the aluminum foil over the napkin. In this way, what we are doing is providing more darkness to the germination process of the cantaloupe seeds and further preserving the moisture of the seeds.

You should also place the cantaloupe seeds wrapped in a napkin inside a plastic container and wrap them with a transparent plastic wrap. This way, you will be able to observe the germination process.

Cantaloupe seeds germinate at room temperature, so we can leave our seeds wrapped in the napkin and the foil in a warm place at home.
