Mouse Melon Cucamelon
Gourmet Vegetable
Mouse Melon Cucamelon (Melothria scabra) is a frost-tender vining fruit from the cucurbitaceae family that produces tiny, cucumber-like fruits in just 70 days. Hardy in zones 9-11, this quirky cultivar thrives in full sun with moderate water and reaches maturity quickly enough to work even in short-season gardens. The small spacing requirements (2 inches apart, 4 inches between rows) make it an excellent choice for compact growing spaces, containers, and trellised gardens.

Highlights
These miniature fruits look like tiny watermelons no bigger than your thumb, with crisp, refreshing flesh that tastes faintly of cucumber and lime. The plants are vigorous climbers that produce prolifically once they get going, rewarding patient gardeners with weeks of continuous harvest. Because roots are sensitive to disturbance, starting seeds in biodegradable pots planted directly in the ground prevents transplant shock and keeps plants thriving.
Common Uses
Mouse melons are eaten fresh, plucked straight from the vine when fully ripe. The whole fruit, including the thin skin, is edible and commonly eaten raw as a snack or added to salads for a burst of crisp, tangy flavor. Some gardeners pickle them when harvests overwhelm fresh consumption.

Care Instructions
Start Indoors
For short-season gardens, start seeds indoors 2-4 weeks before your transplanting date, which should fall within 2 weeks after your average last frost date. Sow seeds 1/4 inch deep into biodegradable pots (roots are sensitive to disturbance, so direct planting of the pot into soil prevents transplant shock). Maintain soil temperature at 70-90°F for germination. Transplant seedlings outdoors once soil has warmed and frost danger has passed.
Transplant Outdoors
Transplant seedlings 2 to 4 weeks after sowing indoors, planting within 2 weeks after your average last frost date when soil temperature reaches 70-90°F. Plant biodegradable pots directly into the ground without removing seedlings, as roots are sensitive to disturbance. Space plants 2 inches apart with 4 inches between rows.
Direct Sow
Direct sow outdoors 1 to 2 weeks after your average last frost date, when soil temperature is 70-90°F. Sow seeds 1/4 inch deep. Thinning is not required.
Harvesting
Harvest Mouse Melon Cucamelon fruits at 70 days after planting once they reach full maturity. Pick fruits when they feel firm to the touch and have developed their characteristic small, rounded shape (roughly the size of a large grape or small marble). These vigorous vines produce continuously throughout the warm season, so regular harvesting encourages more flower and fruit production. Pluck ripe fruits gently from the vine to avoid damaging tender growth.
