Description

(Citrullus lanatus). A classic icebox melon, sweet and juicy. We love this early-maturing, 10- to 15-lb. variety that is believed to have roots in Russia. With salmon-colored, crisp flesh and red seeds, this 10-inch diameter fruit is ideal for slicing at picnics.

Growing Tips: Katanya watermelon prefers full sun, warm weather, and loose, nutrient-rich soil. Mulch to suppress weeds and retain moisture, and water deeply but infrequently to encourage deep roots. Avoid excessive nitrogen, which can lead to excess vine growth at the expense of fruit development. Train vines or use supports in tight spaces.

When to Grow

Start seeds indoors 3–4 weeks before the last expected frost, or direct sow outdoors once soil temperatures consistently reach 70°F. Transplant only after danger of frost has completely passed. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Sow 2–3 seeds per hill at a depth of 1 inch. Thin to the strongest plant after germination. Space hills 3–4 feet apart and rows 5–6 feet apart. Choose a site with excellent drainage and full sunlight, and enrich soil with compost or aged manure before planting.

How to Grow

Water regularly early in the season, reducing frequency once fruit begins to ripen. Fertilize with compost or a balanced organic fertilizer at transplanting and when vines begin to run. Rotate watermelon crops each year and monitor for pests such as cucumber beetles and aphids. Harvest when the belly spot turns creamy yellow and tendrils near the stem dry out.

How to Save Seeds

  • Choose fully ripe or overripe fruits from healthy, true-to-type plants.
  • Scoop seeds from the flesh and rinse in a strainer to remove pulp.
  • Spread seeds on a screen or paper towel in a warm, dry place out of direct sunlight for 7-10 days.
  • Stir daily to ensure even drying.
  • Once completely dry, store in an labeled, airtight container in a cool, dark place.
