Yellow Sweet Spanish Onion Seeds Growing Guide

Yellow Sweet Spanish onions are a popular variety of onion that is known for its mild, sweet flavor and large size. They are relatively easy to grow, making them a good choice for beginner gardeners.

To grow Yellow Sweet Spanish onions from seed, follow these steps:

1. Start the seeds indoors 6-8 weeks before the last frost date in your area. Sow the seeds 1/4 inch deep in a seed tray or pot filled with seed starting mix. Keep the soil moist and warm (65-75 degrees Fahrenheit). The seeds should germinate within 7-14 days.
2. Transplant the seedlings outdoors after the last frost date. Harden off the seedlings by gradually exposing them to outdoor conditions for a week or two before transplanting. Space the seedlings 12-18 inches apart in rows 18-24 inches apart.
3. Water the onions regularly, especially during hot weather. They need about 1 inch of water per week.
4. Fertilize the onions every few weeks with a balanced fertilizer.
5. Harvest the onions when they are mature and the tops start to fall over. This usually takes about 100-120 days after transplanting.
