Plant Information

These are the big, juicy watermelons always featured in the market--the large, elongated light green ones that always seem to have great sweetness.

When and Where to Plant: For earlier crop start seeds indoors 3-4 weeks before night temperatures stay above 55°F/12°C and daytime temperatures stay above 80°F/27°C, then set out. For later crop, sow directly outdoors in sunny location after weather warms. Grow best in light, porous soil. Cultivate and enrich with vegetable food and organic matter. Firm soil over seed.
Care: Mulch to conserve moisture and feed every 3 weeks..
Harvesting: Pick when ripe.

USDA Hardiness Planting Zones

To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

  • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
  • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
