How to Get Cantaloupe Seeds to Germinate


Cantaloupe is a summer treat that is suitable for many home gardens. When ripe, these melons have sweet, orange flesh that is used in fruit salads or served on its own. A warm-season plant, cantaloupe doesn't tolerate frost and cool soil temperatures inhibit germination. Planting cantaloupe indoors allows you to control the climate properly to ensure germination, while also protecting the young plants from disease and insects until they become established. Cantaloupe doesn't tolerate root disturbance well, but sowing in plantable peat pots helps limit this concern.

Step 1

Fill individual peat pots with a potting soil formulated for seed-starting. Water the soil until it is evenly moist but not soggy.

Step 2

Plant two cantaloupe seeds per pot. Sow them to a ½ inch depth.

Step 3

Cover the pots with a plastic bag, which helps preserve moisture in the soil during germination. Set the pots in a warm, 75 to 90 degree Fahrenheit, room to germinate. Best germination occurs at 90 F.

Step 4

Remove the plastic bag when the seeds begin to sprout. Move the cantaloupe to a warm, sunny windowsill and water as needed to keep the soil moist but not soggy.

Tips and Warnings

  • Too little sunlight and too much moisture causes the seedlings to become susceptible to the fungus that causes damping-off disease. Avoid soggy soil and provide at least six hours of sunlight to prevent this.
