RADISH ‘Watermelon’ Vegetable Seeds

Growing Tips for Australian Gardeners:
- Radishes grow quickly, so check often and harvest before they get too big or woody.
- Keep soil moist but not waterlogged to help roots stay crisp and tender.
- If sowing in warmer climates, plant in a spot that gets some afternoon shade to prevent bolting.
- Mulch around the plants to keep the soil cool and hold in moisture.
- Try succession planting every few weeks to enjoy fresh radishes over a longer period.
- Fertilise lightly if needed, but avoid too much nitrogen, as it can cause lush leaves but small roots.
Harvest:
Pick roots when they’re about 3–4 cm across, usually 50–60 days after sowing. They taste best young and tender and are perfect for eating raw.
