Planting Instructions for Catnip

General Sowing Time:

Sow from spring through autumn. In colder regions, spring sowing is recommended so plants have sufficient time to establish before winter.

Position:

Suitable Space:

Suitable for herb gardens, garden beds, borders, raised beds and containers. It is also a useful addition to pollinator-friendly gardens.

Sow Depth:

Sow seeds approximately 0.5 cm deep and cover lightly with fine soil.

Spacing:

Space plants approximately 30 cm apart, with rows approximately 45 cm apart, allowing sufficient room for bushy growth and good airflow.

Height:

Plants generally grow approximately 50–90 cm tall, depending on soil, climate and growing conditions.

Leaf Characteristics:

Produces attractive aromatic grey-green leaves with a soft texture and distinctive fragrance. The foliage contains aromatic compounds that many cats find highly appealing.

Germination:

Seeds generally germinate within 7–14 days under suitable conditions.

Days to Harvest:

Leaves can generally be harvested approximately 90 days after sowing, once plants are well established.

Temperature:

Catnip grows well at approximately 15°C–25°C. Established plants are hardy and can tolerate a range of growing conditions.

Watering:

Keep the soil lightly and consistently moist during germination and establishment. Once mature, Catnip is relatively drought tolerant. Avoid waterlogged soil.

Fertilizing:

Catnip does not require heavy feeding. Grow in well-drained soil with some compost or organic matter. Excessive fertilizer can encourage soft, excessive leafy growth.

Pests/Diseases:

Generally a hardy and low-maintenance herb. Good airflow and well-drained soil help prevent fungal problems. Young plants may need protection from cats until sufficiently established.

Harvesting:

Harvest leaves and young stems once plants are established. For the strongest aroma, leaves can be harvested before or during flowering. Regular trimming encourages fresh, bushy growth.

Wildlife Benefits:

The flowers can attract bees, butterflies and other beneficial pollinating insects, making Catnip useful in pollinator-friendly gardens.

In summary:

Catnip is an easy-to-grow perennial herb producing aromatic grey-green foliage that is loved by many cats. Growing approximately 50–90 cm tall, it is a hardy and attractive addition to herb gardens, borders and containers.
