Learn about Crimson Sweet Watermelon seed germination, fruit development, and harvesting.
Crimson Sweet Watermelon Seeds commonly germinate in approximately 5–10 days when planted in warm, moist soil. Germination may take longer if the soil is too cool, excessively wet, or allowed to dry out. Maintain suitable warmth and moisture, and follow the instructions supplied with your seed packet.
Check for several signs of maturity. The spot where the watermelon rests on the ground usually changes from pale green or whitish to creamy yellow, the rind may become duller, and the tendril nearest the fruit stem often dries and turns brown. Crimson Sweet watermelons commonly mature in about 85 days, but actual harvest time depends on weather and growing conditions.
Crimson Sweet is a vigorous, spreading watermelon variety that generally performs best in open ground. Container growing is possible with a very large, deep container, fertile well-drained potting mix, consistent watering, and plenty of sunlight. Because the vines and fruits can become large, choose a compact watermelon variety instead if space is limited.
