Introduction
Don’t skip growing turnips because they act as a dual harvest, where you can eat both the root and the greens. Who would have thought that the turnip could be quick growing and space-efficient. Now that’s a perfect combination for a new NYC gardener. So, grab your potting soil and get ready to grow the perfect turnip that tastes better than any you’ve had at the store.
The What
Turnips (Brassica rapa) are versatile root vegetables from the mustard family, which also includes cabbage and kale. Their round, white roots with purple tops are nutritious, offering vitamins C and K, fiber, and antioxidants. Both the roots and leafy greens can be eaten. Known for their rapid growth, turnips mature in about one to two months. They are perfect for growing in containers, making them ideal for urban spaces like balconies, rooftops, and terraces.
The Why
In NYC, turnips are a unquique addition to any urban garden. They require minimal care and mature quickly, making them a great choice for busy urban dwellers. Growing turnips in containers is efficient and space-saving, and can be intercropped with plants like peas, radishes, spinach, and lettuce. These companion plants help improve soil health and attract beneficial insects. Homegrown turnips contribute to a sustainable lifestyle and are easy to grow.
Sunlight Requirements
Turnips require 6-8 hours of direct sunlight. Indoors: Not suitable for indoor growing; best grown outdoors in deep pots or garden beds.
Water Requirements
Keep soil consistently moist. Indoors, monitor soil moisture frequently; outdoors, water regularly, especially in full sun conditions. Mulching helps retain moisture.
Temperature Tolerance
Turnips are a cool weather crop and thrive in 40-75°F, ideally 60-65°F. Plant outdoors in March-May and August-September in NYC zone 7b. Cooler weather ensures tender roots.
Container Size
Indoors: 8-10" wide, 10" deep, 2-3 gallons; Outdoors: 10-12" wide, 12" deep, 3-5 gallons
Best Soil Mix
Turnips thrive in loose, well-draining potting mix with compost from kitchen scraps or well-rotted manure.
How to Add Fertilizer
Apply low-nitrogen, high-phosphorus fertilizer 5-10-10 every 3-4 weeks. Organic options: bone meal, rock phosphate, compost. Balanced feeding promotes robust root growth.
Growth Duration
Turnips are ready for harvest 50-60 days after planting, or when the roots are 2-3 inches in diameter. Prefers cooler temperatures; harvest promptly to avoid bolting.
How To Trim
Remove yellowing leaves to maintain plant health. Regular care helps produce tender, flavorful turnips.
Growing Challenges
Yellow Leaves: Ensure good drainage, let soil dry. Pests (Aphids): Spray with soapy water or neem oil. Slow Growth: Use balanced fertilizer. Wilting: Water consistently, avoid waterlogging. Diseases (Downy Mildew): Improve air circulation, use fungicide.
