Oregano Growing Guide

Introduction to Oregano

Oregano (Origanum vulgare) is a hardy perennial herb prized for its pungent, aromatic leaves essential in Mediterranean and Italian cooking. Native to the Mediterranean region, this robust herb thrives in hot, dry conditions and rewards neglect with vigorous growth and intense flavor.[web:12][file:1]

Planting Oregano

Oregano thrives in well-drained soil and full sun. Plant after last frost when soil reaches 70°F (21°C).[web:13][web:14]

• Space plants 12-18 inches apart for air circulation
• Plant in spring after frost danger passes
• Choose full sun location (6-8 hours daily)
• Provide afternoon shade in very hot climates
• Start seeds indoors 8-10 weeks before last frost

Soil Requirements

Oregano prefers lean, well-draining soil with pH 6.0-8.0. Poor soil actually produces better flavor![web:12][web:13]

• Sandy or loamy soil drains best
• Amend heavy clay with compost or sand
• Avoid rich, fertile garden soil
• Mulch lightly with bark or gravel
• Excellent for rock gardens and slopes

Watering and Care

Drought-tolerant once established. Water deeply but infrequently.[web:13][web:16]

• Water when top 2 inches of soil are dry
• Reduce watering after first year
• Avoid overhead watering to prevent fungus
• Winter water sparingly (once monthly)
• Fertilize lightly in spring only

Pruning and Harvesting

Regular harvesting keeps plants bushy and productive.[web:12][web:13]

• Harvest when plants reach 6 inches tall
• Cut stems back to 2-3 inches above ground
• Pinch growing tips regularly
• Remove flowers to prolong leaf production
• Harvest in morning for best flavor

Common Problems

Oregano is remarkably pest-resistant but watch for:[web:12]

• Root rot: Improve drainage immediately
• Aphids/Spider mites: Hose off or use neem oil
• Stem rot: Improve air circulation
• Leggy growth: More sun, less water

Companion Planting

Oregano repels many garden pests:

• Tomatoes - repels hornworms
• Peppers - deters aphids
• Broccoli - repels cabbage worms
• Asparagus - general pest deterrent
• Basil - enhances flavor of both
