What Is A Watermelon Plant?

The watermelon ( Citrullus lanatus) is a member of the Cucurbitaceae family, which includes cucumbers, gourds, squash, and pumpkins.

The watermelon is an annual plant with a sprawling vine that can grow to 10 feet (3 m) in length. The leaves are large, green, and lobed, and the flowers are yellow.

The fruit of the watermelon is round or oval, typically 3-4 feet (91-122 cm) in length, and can weigh up to 100 pounds (45 kg).

The flesh of the watermelon is pink or red, and the seeds are black. Watermelons are grown in tropical and temperate regions worldwide.


What Makes A Good Watermelon Soil

The best soil for growing watermelons is a well-drained sandy loam with a pH between 3.2 and 4.7. Watermelons require medium levels of nitrogen, and should be fertilized every two weeks with a balanced fertilizer. Watermelons should be watered regularly, as they are susceptible to drought stress. When watering, soak the root zone deeply to encourage deep rooting.

How To Propagate & Sow Watermelon Seed Plants

To propagate watermelons, you can sow the seeds directly in the garden after the last frost date in your area. Watermelons can also be started indoors in pots about 6 weeks before the last frost date. Transplant seedlings into the garden after all danger of frost has passed. Space plants about 6-8 feet (1.8-2 .4 m) apart in rows 10-12 feet (3-3 .6 m) apart.

Watermelons are typically started from seed, either planted directly in the garden or started indoors and then transplanted. Sow seeds ½ to 1 inch deep in well-drained soil after all danger of frost has passed and the soil has warmed. Thin seedlings to 24 to 36 inches apart when they are 4 to 6 inches tall.


Watering, Feeding, & Light Conditions For Watermelon Plants

Watermelons require full sun to produce high yields of sweet fruits. Provide plants with at least 8 hours of direct sun each day during the growing season.

Fertilize watermelons every two weeks with a balanced fertilizer such as 10-10-10. Apply ¼ pound per 10 feet of row or 1 tablespoon per plant. Watermelons are heavy feeders and will benefit from additional applications of compost or manure during the growing season.

Watermelons need plenty of water, so the soil should be kept moist but not soggy. Apply a layer of mulch to help retain moisture and control weeds.

Common Problems When Growing Watermelon Plants

Common problems with watermelons include powdery mildew, mosaic virus, aphids, fruit flies, and root-knot nematodes.

To prevent these diseases, avoid overhead watering and plant resistant varieties when available.

Pests and diseases can also be controlled with regular applications of pest-specific insecticides or fungicides according to label directions.


Harvesting Watermelons

To harvest watermelons, wait until the fruits are fully ripe, to test for ripeness, thump the watermelon – if it sounds hollow, it is ready to harvest – the skin will be dull looking and hard to dent with your fingernail. Cut fruits from the vine with a sharp knife, leaving a short section of stem attached. Watermelons can be stored at room temperature for up to two weeks or refrigerated for up to six weeks.
