Catnip

Climate and Growing Conditions

Catnip thrives in temperate climates but can adapt to a range of conditions.

Temperature:

• 15–25°C ideal range
• In hotter areas, consider growing it in pots and moving it into a shadier spot during summer.
•  

Sunlight:

• Full sun to partial shade (at least 6 hours of sunlight daily).

Frost Tolerance:

• Catnip can tolerate light frost but may struggle in very cold regions.
• In cooler areas, consider growing it in pots and moving it indoors during winter.

Preparing the Soil

Catnip prefers well-draining soil with a neutral to slightly alkaline pH (6.0–7.5).

Soil Type:

• Sandy loam or loamy soil is ideal. If your soil is heavy clay, amend it with compost or sand to improve drainage.

pH Level:

• Test the soil pH and adjust if necessary.
• Add lime to raise pH or sulphur to lower it.

Organic Matter:

• Mix in compost or well-rotted manure to enrich the soil.

Sowing Catnip Seeds

 Direct Sowing:

• Choose a sunny spot in your garden.
• Scatter the seeds lightly over the soil surface.
• Cover the seeds with a thin layer of soil (about 1 mm deep).
• Water gently to avoid displacing the seeds.
• Space plants 30 cm apart to allow for growth.

Starting Seeds Indoors:

• Fill seed trays or small pots with seed raising mix.
• Sow 2–3 seeds per cell or pot, covering lightly with 1 mm soil.
• Water gently and place in a warm, sunny location (or under grow lights).
• Seeds typically germinate in 7–14 days.
• Transplant seedlings outdoors once they are 5–7 cm tall and the risk of frost has passed.

Watering and Care

 Watering:

• Keep the soil consistently moist but not waterlogged.
• Water when the top 2–3 cm of soil feels dry.

 Mulching:

• Apply a layer of mulch around the plants to retain moisture and suppress weeds.

 Fertilising:

• Catnip doesn’t require heavy feeding.
• Apply a balanced, slow-release fertiliser once or twice during the growing season.

Pruning and Maintenance

 Pruning:

• Regularly trim the plant to encourage bushier growth and prevent it from becoming leggy.
• Pinch off the tips of young plants to promote branching.

 Deadheading:

• Remove spent flowers to prevent self-seeding and encourage more leaf growth.

 Pests and Diseases:

• Catnip is relatively pest resistant but can occasionally attract aphids or spider mites.
• Use insecticidal soap or neem oil if needed.

Harvesting Catnip

 When to Harvest:

• Harvest leaves and stems just before the plant flowers for the highest concentration of essential oils.

 How to Harvest:

• Cut stems about 5–10 cm above the ground.
• You can harvest multiple times during the growing season.

 Drying:

• Hang stems upside down in a cool, dry, well-ventilated area.
• Once dry, store leaves in an airtight container away from light and moisture.

Growing Catnip in Pots

Catnip grows well in containers, making it ideal for balconies or small spaces.

• Use a pot at least 20–30 cm deep with drainage holes.
• Fill with a high-quality potting mix.
• Place the pot in a sunny location and water regularly.

Common Problems and Solutions

 Leggy Growth:

• Caused by insufficient light.
• Move the plant to a sunnier spot or prune regularly.

 Yellowing Leaves:

• Overwatering or poor drainage.
• Ensure the soil drains well and reduce watering.

 Self Seeding:

• Catnip can spread quickly if not managed.
• Remove flowers before they set seed if you want to control its spread.
