Product Description
Sugar Baby Watermelon is one of the most popular home garden watermelon varieties, valued for its sweet flavour, manageable fruit size and reliable summer performance. It is an excellent choice for gardeners wanting classic red-fleshed watermelons without the oversized fruit of larger varieties.
The vigorous trailing vines produce round, dark green watermelons with crisp, juicy red flesh. Fruits are smaller than many standard watermelons, making them easier to harvest, store and enjoy fresh.
Sugar Baby performs best in warm weather with full sun, fertile soil and consistent moisture. Plants need space to spread and benefit from mulch to conserve moisture, protect fruit and reduce weed competition.

How to Grow Sugar Baby Watermelon
Direct sow seeds into fertile, well-drained soil once temperatures have warmed, or raise seedlings in pots for transplanting after frost danger has passed. Watermelons need warmth, full sun and plenty of space for vines to spread.
Plant into mounds or rows and keep soil evenly moist during germination, flowering and fruit development. Mulch around plants to conserve moisture, suppress weeds and help protect developing fruit from direct contact with damp soil.
Avoid excessive nitrogen once plants are established, as this can encourage leafy growth at the expense of fruit production. Bees are needed for pollination, so encourage beneficial insects and avoid unnecessary insecticide use during flowering.
Allow fruits to ripen fully on the vine before harvesting for the sweetest flavour.
Harvest
Harvest Sugar Baby watermelons when the tendril closest to the fruit has dried, the underside turns creamy yellow and the fruit gives a deep, dull sound when tapped. Cut fruit from the vine rather than pulling to avoid damaging the plant.
