How to Sow White Flower Catnip Seeds 

White flower catnip is a beautiful herb adored by pets and admired for its fragrant minty aroma. This hardy perennial is native to Asia, Europe, and the Middle East, and can grow to a height of 24 inches, making it a perfect ground cover plant that will spread each year. In addition to being a favourite for cats, white catnip attracts pollinators like bees and butterflies, and its delicate white blooms last throughout the summer. As a versatile herb, it’s harvested for use in catnip-based treats or as a fragrant garden addition. 

When and Where to Sow White Flower Catnip Seeds 

• Indoor Sowing: Sow white catnip seeds in pots or seed trays indoors, maintaining a consistent temperature of 15°C for the best germination rates. Use well-draining, high-quality seed compost to ensure healthy seed development.
• Outdoor Sowing: Wait until mid-spring to sow seeds directly outdoors when the weather has warmed up. Ensure the soil is well-prepared and worked, and cover the seeds lightly if there is any risk of cold spells. 

Ideal Growing Conditions for White Flower Catnip 

• Soil Requirements: Catnip thrives in well-drained soil. A light, nutrient-rich compost will support the plant’s growth and prevent waterlogging, which can cause root rot. 
• Sunlight: Catnip prefers full sunlight but will tolerate partial shade. Choose a location in your garden that receives ample sunlight for optimal growth and flower production. 
• Temperature: Ideal germination temperatures range from 15-20°C. Ensure seedlings are protected from frost, as young plants are less tolerant to cold than mature catnip. 

How to Sow White Flower Catnip Seeds Indoors 

1. Sowing Depth and Spacing: Sow the seeds sparingly on the surface of well-drained compost in seed trays or pots. Lightly press the seeds into the compost but do not cover them fully, as they need some light to germinate. 
2. Watering: Keep the soil moist but not waterlogged. Maintain a consistent temperature of 15°C to encourage germination. 
3. Germination Period: Be patient, as germination may take between 2-3 weeks. Ensure the soil remains moist during this period to promote healthy seedling development. 
4. Transplanting: Once seedlings reach about 5cm (2 inches) in height, they can be transplanted to their final growing location, either in pots or directly into the garden. Space plants at least 30cm apart to allow for their spreading nature. 

How to Sow White Flower Catnip Seeds Outdoors 

1. Preparing the Soil: Before sowing, ensure the soil is well worked and free-draining. Loosen the soil and mix in some compost to improve its quality. 
2. Sowing Depth: Sow the seeds sparingly on the surface of the soil in mid-spring when temperatures have warmed up. Cover lightly with a fine layer of soil or compost. 
3. Watering and Sunlight: Water regularly to keep the soil moist and position the seeds in a location that receives full sun. Germination will take up to 3 weeks. 
4. Transplanting Seedlings: Once the seedlings are around 5cm (2 inches) tall, transplant them into their final location, spacing them at least 30cm apart. 

Caring for White Flower Catnip Plants 

• Watering: Keep the soil consistently moist, particularly during germination and early growth. Once established, catnip is drought-tolerant but should still be watered during extended dry periods. 
• Pruning: Regularly harvest and prune the plants to encourage bushier growth and prevent leggy stems. Deadhead the spent flowers to promote continuous blooming. 
• Fertilising: Catnip generally doesn’t need much feeding, but a light application of compost in the spring can help support vigorous growth.
