Troubleshooting
Seeds not germinating
Ensure seeds are fresh, sown at the correct depth, and kept consistently moist and warm. Try a different seed starting mix if the current one is suspected to be poor.
Seedlings are leggy and weak
Provide more light. Ensure seedlings are kept in a bright location, such as a sunny windowsill or under grow lights. Avoid excessive heat.
Onion bulbs are small
Ensure adequate spacing, consistent watering, and sufficient sunlight. Amend the soil with compost before planting. Harvest time may influence bulb size; ensure they are left long enough to mature if bulb formation is desired.
Pest infestation (e.g., onion fly)
Use row covers or netting to protect young plants. Practice crop rotation. Keep the garden area clean to reduce overwintering pests.

Setup, Compatibility & Care
Setup: For best results, sow seeds indoors in February or March. Use a well-draining seed compost and sow thinly in trays or small pots. Cover lightly with compost and water gently. Keep the soil consistently moist and warm. Once seedlings have developed a few true leaves and the risk of frost has passed (typically late spring), they can be transplanted outdoors into well-prepared garden beds, pots, or window boxes.
Compatibility: 'Ruby Red' onions are compatible with most garden soils, provided they are well-drained. They can be grown alongside other common vegetables in garden beds or mixed containers. Ensure they receive at least 6 hours of sunlight per day.
Care: Water regularly, especially during dry spells, to promote healthy bulb development. Avoid overwatering, which can lead to rot. Weed the area around the plants consistently, as onions do not compete well with weeds. Do not disturb the soil around the bulbs once they start to swell. For spring onion harvesting, pull plants out as needed once they reach a usable size.
