How to Grow Moon and Stars Watermelon
Citrullus lanatus 'Moon and Stars'
Moon and Stars Watermelon is an heirloom variety known for its unique patterned rind and sweet, juicy fruit. Gardeners grow this warm-season crop to enjoy refreshing slices during summer festivals or backyard gatherings.
Starting Moon and Stars Watermelon: indoors or direct sow?
🌾 Sow directly in the garden — Moon and Stars Watermelon is not usually started indoors.
This plant is direct-sown only in warm soil after all risk of frost has passed; do not attempt to start seeds indoors or transplant seedlings.
Soil, care & harvest
Prepare loose, well-draining soil with a pH between 6.0 and 7.0. As a warm-season crop, you must wait until after the last spring frost when the ground is fully warm before sowing directly outdoors. Do not start indoors; these seeds are best planted in the garden bed once frost danger has passed completely.
Space plants 48 to 72 inches apart to allow vines to spread freely, as trellising is generally unnecessary for this sprawling variety. Provide 1 to 2 inches of water weekly with deep soakings, and apply mulch around the base to retain moisture. Feed regularly if soil nutrients are low to support vigorous vine growth.
Watch for cucumber beetles, squash bugs, aphids, and spider mites; use row covers or insecticidal soap early in the season. Prevent fungal diseases like powdery mildew by ensuring good air circulation and avoiding overhead watering. Harvest fruit 90 to 100 days after sowing when the rind hardens and loses its sheen.
