Care Guide for Central Texas (Zone 8b)

---

Sun Requirements

• Carrots love full sun – aim for 6-8 hours daily.
• Light afternoon shade helps prevent bitterness during peak summer.
• Mulch keeps soil cool and moisture steady.

Watering

• Water deeply 2-3× weekly depending on rainfall.
• Keep soil evenly moist; dry spells cause woody roots.
• Avoid overhead watering to reduce leaf disease.
• Mulch helps retain moisture and prevent soil crusting.

Soil & Fertilizer (Organic‑Only)

Use loose, sandy loam rich in compost.
Work soil 10-12 in deep; remove rocks and clumps.

Container

• Every 3 weeks alternate diluted fish emulsion (½ strength) and compost tea
• Monthly worm castings
• Root crops need steady, gentle feeding for uniform roots
• Too much nitrogen = big leafy tops, small or forked roots
• Containers dry out fast, so keep moisture consistent

In‑ground

• Every 3 weeks compost tea and worm castings
• Diluted fish emulsion only if growth slows
• Healthy soil biology supports strong root development
• Heavy nitrogen causes excessive tops and poor root formation

Organic Pest Control

Watch for:

• carrot rust fly
• aphids
• root knot nematodes

Treat with neem oil or insecticidal soap at dusk.
Use floating row covers to protect seedlings.
Encourage ladybugs and lacewings.

Container vs In‑Ground Care

Container:  

• Use a 1‑gal pot ≥ 10 in deep with drainage holes.
• Terracotta helps prevent soggy roots.

In‑Ground:  

• Plant in raised beds or loosened soil enriched with compost.
• Austin clay needs amendment for drainage.
• Thin seedlings to 1-2 in apart for uniform roots.

Harvest Instructions

• Harvest when roots reach 7-8 in and are smooth and firm.
• Smaller carrots are sweeter and more tender.
• Loosen soil before pulling to avoid breakage.
• For extra sweetness, harvest after cool nights or light frost.

Drying & Storage

• Remove tops immediately.
• Store unwashed roots in a perforated bag in the fridge 2-4 weeks.
• For long‑term storage: keep in damp sand in a cool cellar.
• Avoid washing until ready to eat.
