How to Grow Indoors With Red Onions

Red onions are low-growing perennial plants native to Eastern Europe and Asia. The onion family includes all bulbs, roots and seeds including white, green and yellow varieties. They thrive in dry, warm weather. Growing them is easy, they just need the right conditions for growth.

Red onions can be grown indoors from red onion seeds obtained at a nursery or online. Red onions grow best in cool, loose soil. Before planting, amend the soil using fine-grit compost and organic granular fertilizer for proper nutrients.

Sow red seeds indoors about 8 weeks prior to the last average frost in your region. Harvest them about 2 weeks later, but do not harvest until the plant starts to flower. Do not place them in a plastic bag as they will start to dry out, allowing moisture to escape while drying. They will bloom in full sun in the fall. Remove any green growth near the stem end and prune the remaining mature roots.

When the garden is established, maintain it with low-tolerable soil that drains easily. If you have had to grow them indoors for several years, you may want to consider reporting them at the end of each season. The best time to repot garden onion seeds is late in May or early in June when temperatures are high. Plant your garden in large quantities so the soil drains well.

When the Red onion sets are reaching maturity, they will be ready to harvest. The best time to harvest them is about a week after the leaves begin to turn golden-green. Set the stem end of the plant on its side, allowing the harvest end to reach vertical. Cut the mature stem end gently with a pair of garden shears or a sharp knife.

Water the Red onion seedlings thoroughly and replace the soil cover. Continue to water the plants through the summer months when they are not growing too vigorously. The Red onion will seed easily at this time. When the fall rains begin, continue to water the seedlings through the dry winter months. This will allow the Red onion to reach full fruition.

Once the root system has provided the maximum amount of nutrients, spread the clumps for about a foot beneath the ground. Water them throughout the growing season. The soil will act as a sponge and soak up all the nutrients from the new root system. The soil will also become very well-drained and hold more nutrients for the next growing season.

There is one trick to growing red onions that is not commonly known by many gardeners. It is best to plant the Red onion seeds in partial sun or partial shade. Providing adequate drainage is another way to ensure that the root system can get all the nutrients it needs. Also provide the plants with fertilizer when it starts to get dark. Fertilizer should be applied early in the growing season for the first two weeks to ensure the plants have everything they need to start producing their crops.

During the growing season indoors, it is best to seed them before you plant them outdoors. Sowing them just before a last frost date in your area will ensure they are planted before the frost. The last frost date is usually set a few weeks before your local growing season starts. The earlier you seed them, the better chance they have to survive. It is also important to avoid over-sowing.

When you have chosen your location, you can now place your Red Onion seeds evenly inside your vegetable garden planter. You will want to leave about two to five inches of space between each seedling. Do not allow the seedlings to overlap. If they do, the roots will eventually cause the sapling to collapse. It is also best to plant them right after receiving the seeds to ensure they are planted properly.

Once the Red Onion seeds are planted, they need to be kept dry. This is very important because if they are not kept dry, they will not germinate. Over watering can cause the seeds to rot, while low moisture allows the germination process to be slower. Watering every day during the growing season indoors should be sufficient.

The beauty of Red Onion seeds indoors is that they can be used year round. You can place them in the refrigerator for storage or sprout new plants using them at the beginning of each growing season. These seeds can also be stored in the freezer for later use. They will germinate in the freezer but will not grow as fast as those that were sown outdoors. Red Onion seeds are an easy way to grow indoor plants that will provide colorful flowers and tasty herbs for you and your family to enjoy for years to come.
