Description
Start seeds indoors: Densuke watermelon seeds can be started indoors about 4-6 weeks before the last expected frost date in your area. Use a seed starting mix and keep the soil moist but not too wet..Transplant seedlings: After the last frost date has passed, transplant the seedlings into a sunny location with well-draining soil. Space the plants about 6 feet apart in rows that are about 8 feet apart..Water and fertilize: Water the plants deeply once or twice a week, depending on rainfall. Fertilize with a balanced fertilizer every 4-6 weeks..Provide support: As the vines grow, they will need support to keep them off the ground. You can use trellises or stakes to support the vines..Harvest: Densuke watermelons are typically ready to harvest about 85-90 days after planting. Look for a deep green color with distinct stripes and a yellow or cream-colored spot on the underside of the fruit. The fruit should also sound hollow when tapped.
