🍃 Main Characteristics

🌱 Growing Instructions

1. Sowing: Sow 2 seeds per pot, about 2–3 cm deep, approximately one month before transplanting outdoors.

2. Seedling selection: After germination, keep the strongest seedling.

3. Hardening: Gradually acclimatise seedlings before planting outdoors.

4. Planting: Transplant when the soil is warm and all risk of frost has passed.

5. Spacing: 60–90 cm between plants, 180–250 cm between rows.

6. Watering: Keep the soil evenly moist during early growth; reduce watering as fruits ripen to enhance sweetness.

7. Mulching: Cover the soil around plants with organic mulch (straw, compost, or black garden fabric) to retain moisture, suppress weeds and protect fruits from contact with the soil.

8. Harvesting: Fruits are ripe when the rind becomes dull and the underside turns yellow.
