How to grow Watermelon

  • Full Sun

Keep the plants under plastic bags till the flowers appear on the vine.

The most reliable sign of ripening occurs when the small tendril opposite the fruits pendule (stem attachement) changes from green to brown and becomes dry.

Plant in a location that enjoys full sun. Zone 4 to 9 are typically the USDA Hardiness Zones that are appropriate for this plant (although this can vary based on your microclimate). Try to keep the ph of your soil between the range of 6.5 and 7.5 as Watermelon likes to be in weakly acidic soil - weakly alkaline soil. Keep in mind when planting that Watermelon is thought of as tender, so remember to wait until your soil is warm and the night time temperature is well above freezing before moving outside.

Growing Watermelon from seed

You can sow watermelon seeds in mounts or rows. Plant three to four seeds in each mount you make.

Sow 0.39 inches (1.0 cm) deep with a guideline distance of 8.12 feet (2.50 metres). Soil temperature should be kept higher than 16°C / 61°F to ensure good germination.
