Summary:

  • Plant onions in early spring in well-drained, fertile soil.
  • Choose sweet varieties and enrich your soil with compost.
  • Ensure consistent watering and regular feeding for healthy growth.

Growing onions is a rewarding and straightforward process that can yield delicious results. This guide will walk you through the essentials of planting, caring for, and harvesting onions, ensuring you get the best out of your farm.

Plant onions in early spring once the ground is workable. Onions thrive in sunny spots with fertile, well-drained soil. Space onion plants six inches apart in rows that are 12 inches apart. This spacing allows each plant to receive ample sunlight and nutrients, promoting healthy growth. Early planting helps onions establish before the intense summer heat. If you plant them too late, the hot weather can stress the plants and reduce bulb size.

For sweet onions, choose varieties known for their mild flavor, like Texas Sweet or Walla Walla. Start with Bonnie Plants® onion slips, which are strong and reliable. Plant these in soil with a pH between 6.0 and 6.8 for the best results. The right variety ensures you get the flavor and size you desire. Sweet onions are popular for their mild taste, making them perfect for salads, sandwiches, and cooking.

Improving your soil is crucial for successful onion growth. Mix several inches of aged compost or other rich organic matter into your farm bed. This enriches the soil, providing essential nutrients for your onions. Raised beds or mounded rows are ideal, especially if your soil is heavy clay. Good soil structure enhances drainage and root development. Compost also boosts the soil’s ability to retain moisture and nutrients, essential for onion growth.

Onions have shallow roots and need consistent moisture. Water your onions whenever the top inch of soil becomes dry. This ensures the roots can absorb enough water, preventing interruptions in their growth. Inconsistent watering can cause onions to split or become tough. Mulching can help retain soil moisture and keep weeds down, which compete for water and nutrients.

To get the best results, keep your onions fed with continuous-release plant food. This provides a steady supply of nutrients, helping your onions grow strong and healthy. Onions are heavy feeders and benefit from regular fertilization. Using a balanced fertilizer, rich in nitrogen, phosphorus, and potassium, supports leaf growth and bulb formation.

Onions can be harvested at almost any size. Young onions, known as scallions or spring onions, can be pulled just a few weeks after planting. For full-sized bulbs, wait until the tops turn yellow and fall over. After harvesting, cure the onions in a warm, airy location for 7 to 10 days to prevent rot. Curing helps onions develop a protective skin, extending their storage life. Properly cured onions can be stored for months in a cool, dry place.

Keep an eye out for pests like onion thrips, aphids, and onion root maggots. These can affect the health of your onions. Contact your local government agency for pest control advice. Regular inspection and prompt action can save your crop. Using organic or chemical treatments can keep pests at bay and ensure a healthy harvest.

After curing, clip off the tops and roots of your onions. Store them in a cool, dry place. Very sweet onions can be wrapped in newspaper and stored in the fridge for longer freshness. Proper storage prevents sprouting and decay. Sweet onions are more perishable due to their high water content, so refrigeration can extend their usability.
