Watermelon Seeds for Planting – Non-GMO Heirloom

The sweetest summer fruit worth a spot in your garden

Watermelon (Citrullus lanatus) is the quintessential summer fruit, a heat-loving vine grown for its crisp, juicy, sugar-sweet flesh. Varieties range from big oblong picnic melons to small, quick round icebox types that fit a home garden and refrigerator, with red, pink, or golden interiors. Each vine sprawls with deeply cut leaves and yellow flowers before setting fruit that swells dramatically through the hottest weeks of summer.

How to grow watermelon from seed

Watermelon needs heat, sun, and room to run. Sow watermelon seeds about an inch deep in full sun after all danger of frost has passed and the soil is warm, spacing plants roughly 3 to 4 feet apart. Most varieties need about 80 to 100 days of warm weather to ripen, so give them your sunniest spot, steady moisture while the fruit forms, and a long season. For the full step-by-step, see our complete guide to growing watermelon from seed.

How to use watermelon

Watermelon is at its glorious best chilled and sliced into wedges on a hot day. Cube it into fruit salads, blend it into refreshing agua fresca and slushies, or pair it with feta, mint, and lime for a classic summer salad. The rind can be pickled into a sweet-tangy preserve, and frozen watermelon chunks make a simple, cooling treat straight from the freezer.

Watermelon and its cucurbit cousins

If you love growing watermelon, its cucurbit relatives thrive in the same warm bed. Try melons for fragrant honeydew and muskmelon types, cantaloupe for sweet orange-fleshed fruit, or cucumbers for crisp fruit on the same kind of vine. You can explore the full range in our vegetable seeds collection.
