Days To Harvest: 90
How to grow: Plant in full sun.
Plant after danger of frost has passed. Side-dress with nitrogen when vines begin to run. Watermelons mature in 80-100 days from seed. Young transplants are typically 14-21 days old.
Spacing: Plant 48″ apart in 8′ rows.
Height: Grows 6″ to 8″ tall.
Outstanding Features: Tastes great!
Tips: Plant two plants every 48″ to ensure a successful crop. Placing a straw matt under the watermelon will prevent the bottom of the watermelon from rotting as it continues to grow. Fertilize well by side-dressing the rows with nitrogen when vines begin to run and keep the soil moist at all times.
