Quick facts

About Watermelon

Citrullus lanatus, commonly known as watermelon, is an annual climbing plant from the Cucurbitaceae family, prized for its large, sweet, and juicy fruits. Its trailing stems produce lobed leaves and yellow flowers, leading to the distinctive watermelons with smooth or striped green skin and red or pink flesh. It is ideal for sunny vegetable gardens or for covering large ground areas in spacious gardens, providing a refreshing summer harvest.

Care tips

Watermelon requires full sun (at least 6-8 hours daily) and warm temperatures for optimal fruit development. It needs consistent and abundant watering, especially during flowering and fruit development, avoiding waterlogging. It prefers well-drained soil, rich in organic matter, and with a slightly acidic to neutral pH. A common mistake is planting seeds or transplanting seedlings too early in spring, before the risk of frost has passed and the soil has warmed up sufficiently.

How to save a dying Watermelon

Warning signs
Wilting, yellowing leaves (especially older ones), small/deformed fruits, premature flower/fruit drop.
