Updated July 2026

Sugar Baby is the go-to icebox watermelon for small gardens and short seasons. Its compact, round fruit runs 8 to 12 pounds with a dark green rind and deep red, fine-textured flesh that is intensely sweet. Ripening early in about 75 days on relatively short vines, it is a top pick for northern growers, containers, and even trellises. If you want personal-sized melons that fit in the fridge and finish fast, Sugar Baby delivers.

Quick start

Sow seeds about 1 inch deep in warm soil at least 70F, or start indoors a couple of weeks early in peat pots for a head start. Thin or space plants 2 to 3 feet apart, or train the compact vines up a trellis with slings to support the fruit. Water deeply and evenly, easing off as the melons ripen. Harvest early, around 75 days, when the nearest tendril dries, the ground spot turns creamy, and it thumps hollow.

Best tip

Sugar Baby is the icebox melon for gardeners short on season or space. Because it ripens early in about 75 days, even northern growers and cool-summer regions can succeed: warm the soil with black plastic, and start seeds indoors a few weeks early to get a jump. The compact vines take well to containers and trellises, so support each small melon in a sling. Ease off water near ripening for concentrated sweetness.

Frequently asked questions

How long does Sugar Baby watermelon take to grow?

Sugar Baby is an early icebox melon that ripens in about 75 days, making it one of the best choices for short seasons and northern gardens. It can be direct-sown in warm soil or started indoors a few weeks early.

How big does a Sugar Baby watermelon get?

Sugar Baby produces small, round icebox melons about 8 to 10 inches across and 8 to 12 pounds, with a dark green rind. The deep red flesh is fine-textured and very sweet, and the compact size fits easily in the fridge.

Why choose Sugar Baby watermelon?

Its early maturity, compact vines, and small fridge-friendly fruit make Sugar Baby ideal for small gardens, containers, cool climates, and short growing seasons. Each vine sets several personal-sized melons that are intensely sweet.

Can I grow Sugar Baby watermelon on a trellis?

Yes. Because the melons are small and the vines relatively compact, Sugar Baby is one of the best watermelons for trellising in small spaces. Support each ripening fruit in a cloth or netting sling so its weight does not pull it from the vine.
