How to Save Cantaloupe Seeds for Next Year?

Last year I visited California to help my uncle pick Cantaloupe (Cucumis melo var. cantalupensis) fruits and pack them for the market.

After learning about the gross harvest of Cantaloupe and its income, I could not blink my eyes. And with that motivation, I added new crops to my farm and became able to build my long-desired farmstead with only Cantaloupe.

Cantaloupe is a summer annual plant that grows naturally in zones 4-10. 

The vine can grow 15-18 inches in height and 72 inches in spread. A single Cantaloupe plant can produce four to eight delicious melons, with each fruit weighing 0.5 to 5 kilograms.

Now you know what the Cantaloupe seeds look like; you can buy a Cantaloupe from the store, extract its seeds, and plant it immediately.

Or even better, you can store the seeds for better use in the future.

How to Harvest Cantaloupe Seeds?

To harvest the Cantaloupe seeds, you need the fruit to mature completely first. The process from germination to maturity takes about 65-90 days.

If the fruit’s stem end gives off a pungent melon smell, you can conclude that the seeds are ready. You need to wait for the melon to become ripe and detach itself off the stem to be able to get the seeds.

To harvest the Cantaloupe seeds, you will need the following equipment.

Isopropyl AlcoholTo sterilize the gardening equipment
Safety GogglesFor extra protection
Gardening GlovesTo protect the hands
Kitchen KnifeTo cut the fruit open
Glass JarTo keep the seeds

After successfully collecting the equipment, you can move on to the harvesting process.

  • Sterilize the equipment with isopropyl alcohol before harvesting the seeds.
  • Take the kitchen knife and make a linear cut on the Cantalope fruit.
  • Separate the two halves of the fruit to reveal the seeds.
  • Gently scrape out the seeds and remove the surrounding membrane.
  • Place the seeds over a paper towel or plate and let them dry.

You can also check the viability of the seeds by placing them in a transparent jar filled with warm water. Let the seeds stay there for about 3-4 days.

Make sure the Cantaloupe you use for seeds is planted at least 800 feet away from other melons. 

Cantaloupe seeds that sink in the water are viable and ready to be planted, whereas the seeds that float on the top are not good.

Once you check the seeds, discard the water with bad seeds and keep the good seeds for future use.

How to Save and Store Cantaloupe Seeds?

After you successfully extract the seeds, you must make preparations to store the said seeds to plant them when needed.

To keep the seeds viable for planting in the future, follow the steps.

  • You must know that you must keep the seeds on a paper plate to let them dry completely.
  • Stir the seeds, and do not let those seeds stick to the paper plate. Repeat the process every day.
  • The seeds may take about 5 to 7 days to dry out completely.

  • Store the extracted Cantaloupe seeds in an airtight container in a dark, cool, and dry location. Many people prefer to store the seeds in the refrigerator or their basement.

If the seeds come in contact with moisture and humidity, they will go bad, and so will your dreams of planting them next year.

Remember to let the Cantaloupe seeds dry completely before storing them. If they do not dry properly, mold can grow on the seeds.

Cantaloupe seeds have a longer shelf-life. If you properly store the seeds, they will not lose their viability for about five years.

I suggest you label the envelope properly with its harvest date to know your seeds at the time of planting.
