Red Onion Seeds

Red onions take about 90 to 120 days, or roughly 3 to 4 months, to fully mature, depending on the variety and whether you’re growing them from seeds or onion sets. If you’re starting from seeds, expect around four months until they’re ready to harvest. On the other hand, growing from onion sets speeds things up a bit, with maturity reached in about three months. Just plant the root end of a mature onion into the soil—soon enough, you’ll have fresh, tender green shoots ready to enjoy!

Red onions take about the same time to grow as any other onion variety. They're a biennial, just like other onions, and can be grown from seeds, onion sets, or even another onion. To help them thrive, make sure they’re in well-drained, slightly acidic soil, and give them consistent watering—especially during dry spells. They’ll also need at least 6 hours of sunlight each day. When the tops turn yellow and fall over, it’s time to harvest your onions!

Absolutely! Red onions are loaded with goodness thanks to their high levels of antioxidants like anthocyanins and quercetin. These powerful compounds help support heart health, fight inflammation, and may even lower the risk of some chronic diseases. Plus, they’re a great source of Vitamin C and fiber, making them a tasty and healthy addition to your meals!

Of course! Red onion seeds love warmth to get going—cooler temps can slow down their growth. Try to keep the soil temperature around 24°C for the best germination results. Also, make sure the soil stays consistently moist (but not soggy!) and give them plenty of sunlight. With the right warmth, water, and light, your red onions will sprout in no time!

When growing red onions, keep a few key things in mind: soil temperature, moisture, seed quality, and how deep you plant the seeds. Try to keep the soil at around 24°C and make sure it stays consistently moist, but not too wet. If the seeds are old or poorly stored, they might not sprout at all. And don’t forget about planting depth—sow them about ½ to 1 inch deep. If they’re are sown too deep, they might struggle to break through the soil.
