Growth Stages

1

Seedling

7-10 days

Tiny seedlings emerge with two cotyledons (seed leaves) and develop their first true leaves with characteristic lobed shape.

Keep soil consistently moist. Thin seedlings to proper spacing once they have 2-3 true leaves. Protect from strong winds and excessive heat.

2

Leaf Development

2-3 weeks

Rapid production of deeply lobed, dark green foliage. Plants focus energy on leaf expansion rather than root development.

Begin harvesting outer leaves once plants reach 6-8 inches tall. This encourages bushier growth and more leaf production. Fertilize every 2-3 weeks with balanced or nitrogen-rich fertilizer.

3

Vegetative Growth

2-4 weeks

Vigorous leaf production with progressively larger and more numerous lobed leaves. Root development remains minimal.

Continue harvesting outer leaves regularly for continuous production. Provide consistent moisture and cool temperatures. Maintain adequate spacing to improve air circulation.

4

Peak Harvest

3-6 weeks

Plants are fully bushy with abundant tender greens at their nutritional and flavor peak. Roots remain small but edible.

Harvest leaves regularly to maintain tenderness and encourage more production. Cut or pinch outer leaves from the base. Can tolerate light frosts and actually improve in flavor after exposure to cold.

5

Late Season & Storage

4-8 weeks or until frost

Continued leaf production throughout fall and into winter in cold climates. Greens become more tender and sweeter after frost.

Plant can be harvested until hard freezes occur. In mild climates, may overwinter. Small roots can be harvested anytime after 60 days if desired.

  • Spray with strong water stream, use insecticidal soap, introduce ladybugs, apply neem oil

  • Rotate crops, avoid planting brassicas in infected soil for 5+ years, ensure good drainage, lime acidic soils

  • Improve air circulation, avoid overhead watering, apply sulfur dust or fungicide, remove infected leaves

Harvest Tips

Begin harvesting outer leaves when plants reach 6-8 inches in height by cutting or pinching them from the base. Harvest regularly every 7-10 days to encourage continuous production of tender new growth. The entire leafy crown can be harvested at once for larger yields, or pick individual outer leaves for extended harvests. Leaves are most tender and flavorful when young and after cool weather or light frosts. Small turnip roots can be harvested anytime after 60 days, but Seven Top is grown primarily for greens. Harvest in the morning after dew dries for best quality.

Fun Facts

  • 🌱 Seven Top earned its name because it produces at least seven harvestable leaves per plant in cool conditions, making it exceptionally productive for greens compared to other turnip varieties.
  • 🌱 This variety is extremely cold-hardy and actually becomes sweeter and more tender after light frosts, as the plant converts starches to sugars as a cold-weather survival mechanism.
  • 🌱 Turnip greens have been cultivated for thousands of years and were more valued historically than the roots themselves in many cultures, particularly in Asia and Mediterranean regions.
