Care Guide for Central Texas (Zone 8b)

---

Sun Requirements

• Turnips prefer full sun, but can tolerate light afternoon shade in summer.
• Aim for 6-8 hours of sunlight daily.
• Mulch around plants to keep roots cool and retain moisture.

Watering

• Water deeply 2-3× weekly depending on rainfall.
• Keep soil evenly moist but not soggy.
• Dry soil can make roots woody and bitter.
• Mulch helps maintain steady moisture and temperature.

Soil & Fertilizer (Organic‑Only)

Use loose, well‑draining soil rich in organic matter.
Mix compost into native soil to improve texture and nutrients.

Container turnip

• Monthly alternating diluted fish emulsion (½ strength) and compost tea
• Monthly worm castings
• Light‑to‑moderate feeder; avoid heavy nitrogen to prevent woody roots and excessive leaf growth
• Containers dry out faster, so monthly feeding keeps roots tender and foliage balanced

In‑ground turnip

• Monthly compost tea and worm castings
• Diluted fish emulsion only if growth is weak
• In‑ground plants often need less feeding because soil retains nutrients better
• Heavy nitrogen encourages leafy tops and smaller roots

Organic Pest Control

• Watch for:
  • flea beetles
  • aphids
  • root maggots
• Treat with neem oil or insecticidal soap at dusk.
• Use floating row covers to protect young plants.
• Encourage ladybugs and lacewings for natural control.

Container vs In‑Ground Care

Container:  

• Use a 1‑gal minimum pot with drainage holes; deep pots allow root development.
• Terracotta helps prevent soggy roots.

In‑Ground:  

• Plant in raised beds or loosened soil enriched with compost.
• Austin clay needs amendment to drain properly.
• Thin seedlings to 3-4 inches apart for uniform roots.

Harvest Instructions

• Harvest when turnips are 2-3 inches wide and smooth.
• Smaller roots are sweeter and more tender.
• Pull gently to avoid breaking tops.
• Greens are edible too - harvest young for best flavor.

Drying & Storage

• Turnips store well in the fridge for up to 2 weeks.
• For longer storage:
  • remove greens and keep roots in a cool, humid place
  • pickle or ferment for winter use
• Avoid washing until ready to eat to extend shelf life.
