Jubilee Watermelon Seeds - Large Striped Melons with Red Flesh

Make room for a summer slicing melon with Jubilee watermelon seeds. This variety develops large, elongated fruits with light-green rinds marked by darker green stripes and sweet, crisp red flesh. Give the vines a sunny, spacious bed and a long warm growing season, then enjoy fresh slices at the picnic table.

Choose your seed quantity

This listing is for seeds to plant, not live plants or harvested watermelons. Choose:

• 10 seeds
• 25 seeds
• 100 seeds
• 1 oz seeds, listed at approximately 300 seeds
• 4 oz seeds
• 1 lb seeds

Bulk packs are sold by weight. The 1 oz seed count is approximate; seed size and counts vary by lot.

Variety at a glance

• Variety: Jubilee
• Fruit: Large, elongated to oval watermelons
• Rind: Light green with darker green stripes
• Flesh: Red, crisp, and sweet when properly ripened
• Seeds in fruit: A seeded watermelon, not a seedless type
• Growth habit: Sprawling vines
• Season: Warm-season annual, sensitive to frost
• Site: Full sun and fertile, well-drained soil

Earlier listing information describes fruit around 25–40 lb. Treat this as a potential size range under suitable conditions, not a guaranteed fruit weight. Size, sweetness, and yield depend on climate, pollination, moisture, and plant care.

When to plant

Plant after frost danger has passed and soil is thoroughly warm, generally at least 70°F for direct sowing. Jubilee needs a long warm season; a short or cool summer may not provide enough time to ripen large fruit.

In frost-free climates, choose a locally suitable warm growing window while accounting for heavy rainfall, disease pressure, and extreme weather. Do not assume a particular calendar month guarantees harvest.

Direct sowing

1. Prepare a sunny bed with loose, well-drained soil.
2. Sow approximately 1/2–1 inch deep in warm soil.
3. Water gently and keep the seed zone evenly moist, not saturated.
4. Thin seedlings carefully so the strongest plants have ample space.
5. Allow approximately 3–4 feet between plants and 6–8 feet between rows, adjusting for your growing system and vine spread.

Germination varies with soil warmth, moisture, and seed condition. Cold, wet soil can slow emergence and encourage rot.

Starting indoors

Where an early start is useful, sow in individual pots approximately 3–4 weeks before your intended transplant date. Use a free-draining seed-starting mix, moderate bottom warmth if needed, and strong light after emergence.

Do not keep seedlings indoors until they become root-bound. Gradually acclimate them to outdoor sun and wind, then transplant into warm soil with the root ball intact. Watermelon roots are sensitive to disturbance; avoid pulling seedlings apart.

Watering and feeding

• Maintain consistent root-zone moisture through establishment, flowering, and fruit enlargement.
• Do not wait for repeated wilting before watering.
• Avoid waterlogged soil and sudden swings between drought and heavy watering.
• Mulch after soil warms to conserve moisture and reduce weed competition.
• Feed according to soil needs and fertilizer label directions, avoiding excessive nitrogen.

Water near the root zone where practical. Do not deliberately stress plants with severe drought to try to increase sweetness.

Flowers and pollination

Watermelon vines produce separate male and female flowers, and successful pollen transfer is needed for fruit set. Early flowers may not immediately produce fruit.

If using row covers to protect young plants, remove them when flowering begins so pollinators can reach the flowers. Avoid unnecessary disturbance of visiting bees. Poor pollination and weather stress can cause small fruit to stop developing.

Managing large vines and fruit

Give vines room to spread without crowding paths or neighboring crops. Inspect for local pests and leaf problems, and rotate planting locations where practical.

Place developing melons on a clean, dry support such as a suitable board if needed to reduce direct contact with wet soil. This does not guarantee protection from pests or rot. Ground growing is generally more practical for large Jubilee fruits than a light garden trellis.

Harvest timing

The earlier listing gives approximately 95 days without clearly defining the starting point. Use this as a general long-season reference rather than a guaranteed date from sowing or transplanting.

How to judge ripeness

Use several signs together: the ground spot often becomes creamy yellow, the rind loses some of its glossy appearance, and the tendril nearest the fruit may turn brown and dry. A dry tendril or a hollow sound alone is not a reliable guarantee.

Cut ripe fruit from the vine with clean pruners or a knife rather than pulling it free. Handle large melons carefully to avoid bruising. Watermelons do not become sweeter after picking, so harvest timing matters.

Serving and storage

Wash the rind thoroughly with clean running water before cutting, and use a clean knife and cutting board. Slice, cube, or add the flesh to fresh fruit salads, removing seeds as desired.

Keep whole melons in a suitable cool location out of direct sun and use promptly. Refrigerate cut watermelon promptly in a clean covered container. Discard spoiled fruit or any melon with an unusually bitter flavor.

Seed storage

Store unused seeds sealed in a cool, dry, dark place away from moisture and temperature extremes. Seeds supplied are for planting, not direct consumption or sprouting.
