How to Buy Seedless Watermelon Seeds


Watermelon takes up a lot of space in the garden, but that ice-cold sweet red fruit says summer. Spitting out the seeds might not be so much fun. Seedless watermelons aren't actually seedless. The seeds are immature, tiny, white and virtually undetectable when eaten, according to the University of Illinois. Seedless varieties must be pollinated by a seeded variety to produce fruit.

Step 1

Select a variety that will mature in your hardiness zone. Watermelons are warm season crops that need long, sunny days and balmy nights. Seedless watermelons take 80 to 85 days to mature. That time period is not the length of the growing season, which is from the last frost in spring to the first frost in fall. It's shorter. Days and nights in early spring can be much cooler than the ideal temperatures for warm-season crops.

Step 2

Decide on the size of the watermelon. Seedless comes in a range of sizes from 8 pounds such as big tasty to 20 pounds such as cotton candy.

Step 3

Decide on the color of the watermelon. Of course they're all green on the outside, but there are yellow fleshed types such as honey heart or orange sunshine.

Step 4

Choose a standard pollinating variety to plant at the same time as the seedless watermelon. The seeded variety should have the same maturity dates as the seedless but should look different so you can tell which is which at harvest time. Otherwise the only way to tell is to cut them open.

Tips and Warnings

  • There might be a few light brown soft seeds in your seedless watermelon. Don't bother planting them--they won't grow.
