Oregano Greek

Climate & Timing 

Oregano thrives in warm, sunny climates but adapts to most Australian regions. 

• Cool regions: Sow in spring after frost risk (Sept–Nov). 
• Warm/tropical regions: Avoid extreme heat; plant in early spring or autumn. 

Soil Preparation 

Soil type:

• Well draining, slightly alkaline to neutral soil (pH 6.5–7.0).
• Enrich with compost or aged manure for drainage. 

Containers:

• Use pots greater than 30cm wide with quality potting mix. 

Sowing Seeds 

Depth:

• 2mm surface sow, light aids germination. 

Spacing:

• Thin seedlings to 30 – 50cm apart. 

Germination:

• 7 – 14 days at 18–25°C.
• Keep soil moist but not soggy. 

Care & Maintenance 

Sunlight:

• 6–8 hours daily.
• Partial shade in hot climates. 

Watering:

• Let soil dry between waterings; avoid waterlogging. 

Fertiliser:

• Minimal needs.
• Apply balanced liquid feed monthly if growth stalls. 

Pruning:

Pinch tips to encourage bushiness.

Cut back after flowering. 

Harvesting 

• Begin harvesting leaves 6–8 weeks after planting.
• Snip stems before flowering for peak flavour. 
• Dry leaves by hanging stems upside down in a warm, dark place. 

Companion Planting Guide 

Oregano’s strong scent repels pests and attracts pollinators.

Best Companions: 

• Tomatoes, Capsicum & Chilli: Repels aphids, spider mites, and cabbage moths. 
• Brassicas (Cabbage, Cauliflower): Deters cabbage worms and beetles. 
• Grapes: Protects against pests like grapevine moth. 
• Lavender & Thyme: Shared sun/soil preferences; enhances pest resistance. 

Avoid Planting With: 

• Cucumbers & Zucchini: Competes for nutrients and moisture. 
• Potatoes: Prefers acidic soil (oregano thrives in neutral/alkaline). 
• Mint: Invasive roots overwhelm oregano. 

Seed Saving Guide 

Selecting Plants 

• Choose healthy plants for seeds. 

Harvesting Seeds 

• Allow flowers to mature and turn brown usually late summer.
• Cut seed heads and dry in a paper bag. 
• Shake dried heads to release tiny seeds.
• Sieve to remove chaff. 

Storage 

• Store seeds in airtight containers (e.g., glass jars) in a cool, dark place.
• Label with date and variety. 

 Viability:

• 2–3 years if stored properly. 

Troubleshooting Common Issues 

 Pests:

• Aphids and spider mites – spray with soapy water or neem oil. 

 Diseases:

• Root rot from overwatering – ensure good drainage. 

 Leggy Growth:

• Insufficient sunlight – relocate to a sunnier spot. 

Regional Tips for Australia 

 Tropical Zones:

• Mulch to retain moisture and improve airflow. 

 Cool Zones:

• Mulch heavily in winter to protect roots.
