-
Best Time to Plant:
Turnips are cool-season crops that thrive in the cooler temperatures of spring and fall. For a spring harvest, sow seeds directly in the garden 2-4 weeks before the last expected frost date. For a fall harvest, plant seeds 8-10 weeks before the first expected frost. Turnips can also be planted successively every 2-3 weeks for a continuous harvest.
-
Soil Type:
Turnips prefer well-drained, loose soil rich in organic matter. The ideal soil pH for turnips is between 6.0 and 7.5. Before planting, amend the soil with compost or well-rotted manure to enhance fertility and improve soil structure. Remove any rocks or clumps to allow for smooth root development.
- Spacing:
Proper spacing ensures healthy growth and prevents overcrowding. Sow turnip seeds 1/2 inch (1.3 cm) deep and 1 inch (2.5 cm) apart in rows that are 12-18 inches (30-45 cm) apart. Once seedlings are 2 inches (5 cm) tall, thin them to 4-6 inches (10-15 cm) apart to allow each turnip enough space to grow to its full size.
CARE TIPS
-
Watering:
Consistent moisture is crucial for growing tender, sweet turnips. Water the plants regularly, ensuring the soil stays consistently moist but not waterlogged. Aim for about 1 inch (2.5 cm) of water per week. Mulching around the plants helps retain soil moisture, suppress weeds, and keep the roots cool.
-
Fertilizing:
Turnips are light feeders but can benefit from additional nutrients. Apply a balanced fertilizer, such as 10-10-10, at planting time. Avoid excessive nitrogen, as it can lead to lush foliage at the expense of root development. Side-dressing with compost or organic fertilizers can provide a steady nutrient supply throughout the growing season.
-
Pruning:
Pruning is not typically necessary for turnips, but you should remove any yellowing or damaged leaves to improve air circulation and reduce the risk of disease. This also helps the plant direct more energy towards root development.
HARVESTING
-
When to Harvest:
Turnip Purple Tops are usually ready to harvest 50-60 days after planting, depending on growing conditions. Harvest turnips when they have reached their mature size of about 2-3 inches (5-7.5 cm) in diameter. The tops of the turnips should be vibrant green and healthy.
-
How to Harvest:
Use a garden fork or trowel to gently loosen the soil around the turnips. Carefully pull the turnips from the ground, gripping them by the base of the foliage. Avoid breaking the roots, as damaged turnips do not store well. After harvesting, remove the tops to prevent moisture loss and store the turnips in a cool, humid place.
TROUBLESHOOTING
-
Common Issues:
•Root Maggots: Small white larvae that tunnel into the roots, causing damage and making the turnips inedible.
•Downy Mildew: A fungal disease causing yellow patches on leaves, which eventually turn brown and die.
•Flea Beetles: Small, black beetles that chew small holes in leaves, leading to reduced growth and vigor.
-
Solutions:
•Root Maggots: Use row covers to protect plants from adult flies laying eggs. Rotate crops and avoid planting turnips in the same spot for consecutive years.
•Downy Mildew: Ensure proper spacing for good air circulation and avoid overhead watering. Apply fungicides if necessary and remove affected leaves.
•Flea Beetles: Use insecticidal soap or neem oil to control flea beetle populations. Encourage beneficial insects, such as predatory beetles, which prey on flea beetles.
