Green onions, also known as scallions, are a versatile and easy-to-grow vegetable that can be cultivated year-round with proper care. Understanding the seasonal tasks involved in caring for green onions can help ensure a healthy and productive crop. This month-by-month care calendar provides essential tips for gardeners and farmers alike.
January
In January, focus on planning for the upcoming growing season. If you are in a region with mild winters, you can start planting green onions indoors or in a protected greenhouse. Prepare your soil by adding compost and ensuring good drainage. This is also a good time to order seeds if you haven’t already.
February
February is ideal for starting green onion seeds indoors. Use seed trays or pots with well-draining soil. Keep the seedlings in a warm, bright location and water regularly to keep the soil moist. This early start will give your green onions a head start once the weather warms.
March
As temperatures begin to rise, you can transplant seedlings outdoors if the risk of frost has passed. Choose a sunny spot with rich, well-drained soil. Space the plants about 1 inch apart. Continue to water consistently and mulch around the plants to retain moisture and suppress weeds.
April
April is a great month for planting new green onions directly into the garden. Keep the soil moist and fertilize lightly with a balanced fertilizer. Watch for pests such as aphids or onion maggots and manage them promptly to prevent damage.
May
Green onions should be growing vigorously by May. Thin out overcrowded plants to improve air circulation and prevent disease. Continue regular watering and apply a side dressing of compost or fertilizer to promote healthy growth.
June
In June, green onions are typically at their peak. Harvest green onions as needed, cutting the stalks about 1 inch above the bulbs. Be careful not to disturb the roots of nearby plants. Keep soil moist and weed regularly to reduce competition for nutrients.
July
Continue harvesting green onions in July. To encourage continued growth, avoid overharvesting. Water deeply during dry spells and mulch to conserve moisture. Watch for signs of pests or disease and act swiftly if issues arise.
August
August is a good time to prepare for fall planting. You can also harvest remaining green onions. If you want a fall crop, consider planting a new batch of seeds in late August or early September for a late-season harvest.
September
In September, focus on planting green onions for a fall harvest. Use transplants or direct sow seeds in well-prepared soil. Continue regular watering and fertilizing. Harvest mature green onions before the first frost.
October
October is the time to harvest the last of the green onions and prepare your garden for winter. Clean up plant debris and add compost to enrich the soil. Mulch around remaining plants to protect roots from cold temperatures.
November
In November, focus on protecting your garden beds from cold weather. Cover green onions with straw or mulch if they are still growing in milder climates. Consider planting green onions in containers that can be moved indoors if needed.
December
December is typically a dormant month for green onions in colder regions. Use this time to reflect on your garden’s successes and plan for the next season. Maintain your tools and prepare seed orders for an early start in the new year.
