Onions are relatively easy to grow, making them fun for beginners and New Yorkers (are you both?). You'll need an outdoor spot that gets at least six hours of sun and a container at least 12 inches deep. Might I suggest a trip to your local second hand store? Get creative, New Yorkers!
Onions require 6-8 hours of direct sunlight daily. Indoors: they need a lot of light, ideally 12-16 hours of a grow light daily.
Water regularly to keep soil evenly moist. Indoors, air can dry soil quickly; outdoors, water regularly, especially during hot weather. Mulching helps retain moisture.
Onions are a cool weather crop and thrive in 55-75°F, ideally 60-70°F. Plant outdoors in March-May and August-September in NYC zone 7b. Cooler temperatures prevent bolting and ensure large bulbs.
Indoors: 6-8" wide, 6" deep, 1 gallon; Outdoors: 10-12" wide, 12" deep, 3-5 gallons
Onions prefer well-draining potting mix with organic matter, such as organic compost or worm castings. Indoors, stick to worm castings.
Apply balanced fertilizer 10-10-10 every 3-4 weeks. Organic options: compost, bone meal, blood meal. Higher potassium levels during bulb formation support optimal growth.
Onions are ready for harvest 100-120 days after planting, or when the tops fall over and dry out. Indoors, onions tend to live 4 to 6 months. Outdoors, onions can live for 1 to 2 years if left unharvested.
Remove yellowing leaves to encourage healthy growth. Regular monitoring ensures a good yield of flavorful onions.
Yellow Leaves: Ensure good drainage, moderate watering. Slow Growth: Use balanced fertilizer. Pests (Onion Maggots): Rotate crops seasonally. Wilting: Water consistently. Diseases (Downy Mildew): Improve air circulation.
There are around 10-15 varieties of arugula gardeners commonly grow. One of the perks of growing arugula at home is the opportunity to experiment with different varieties that you won't find at the grocery store.
