Crimson Sweet Watermelon - Garden Seed
Crimson Sweet Watermelon (Citrullus lanatus) is raved about by professional and at-home growers because of its reliable results and uncompromised flavor! High yields and consistent growth is prized because growing watermelon takes all summer long!
Crimson Sweet Watermelon is an annual in zones 3-9. If outside of these zones, consider growing indoors in a greenhouse. The plant will produce flowers over its growth cycle. It is best to deadhead these blooms to promote fruit growth.
Rap the surface of this watermelon. If it lets out a low thud, it is ready to harvest. If the sound is higher pitched, it’s not ready to be picked yet. Where the fruit meets the grown is a good place to check. If the bottom is cream or yellow, it is time to harvest.

Sowing: Can be sown indoors 4-6 weeks before the last frost date or outdoors when night temperatures are above 60° F for two weeks. This will result in an Autumn crop. Plant 3 seeds ½ inch down and cover with ¼ inch of soil. Thin seedlings to 2 seedlings.
Transplanting: First, “harden off” your plant for up to 14 days before transplanting. Prep the bed, by turning the soil under 8 inches. Dig a whole big enough for the entire root structure. Loosen the dirt around the root structure, and place the plant in the whole covering the roots. Water thoroughly. Holes should be at least 12 inches apart.
Soil Preference: A rich fertile loam, well-drained and warm. Prefers a light acidic soil.
Other Tips: Try all of the methods to check for ripeness. Give the thick rind a thump. A dull sound usually means it’s ready. Check the bottom. If it is a cream color rather than white, it may be ready. Scratch the rind. If it comes off fairly easily, that may also be a sign of ripeness.
