Expert tips
The key tip
In full sun and poor, well-draining soil, this Nepeta is virtually indestructible. No fertilizer, no compost: it gets thick and produces fewer flowers.
The common mistake
Overwatering it: it yellows and rots at the crown in humid climates or compacted soil.
The pro's trick
Deadhead spent flowers in July to force a dense second bloom in autumn; it bounces back quickly.
Seasonal watch
In humid late summer (August-September), check the crown: if it softens, it's powdery mildew or root rot; improve air circulation and water less.
Care
Exposure
Install your Nepeta nervosa in full sun for generous flowering and dense foliage. It tolerates very sunny and hot situations well. Light shade may work in very hot regions, but this will reduce the plant's vigor.
Watering
Water moderately after planting to establish the root system. Once established, this drought-tolerant plant requires less water. During very dry periods, occasional watering is sufficient. Avoid excess moisture which promotes root rot.
Soil
Nepeta nervosa prefers well-draining, light, even poor soil. A mixture with sand or gravel works perfectly. Avoid heavy, compact soils that can cause root suffocation.
Pruning and cutting
Cut back faded stems after flowering to stimulate a new wave of blooms. In late winter or early spring, trim the plant lightly to encourage compact branching. Light cleanup removes any dead or damaged parts.
Fertilizer
Fertilizer is not necessary with good soil. On poor soil, a light balanced fertilizer in spring is sufficient. Avoid excess nitrogen which weakens hardiness and promotes fungal diseases.
Diseases and pests
Generally robust, Nepeta nervosa is not very susceptible to diseases. Good air circulation limits fungal problems. In case of excess moisture, watch for powdery mildew. Pests are rare on this well-established species.
Did you know?
Nepeta nervosa, native to the Caucasus and Central Asia, belongs to the Nepeta genus which includes the famous catnip herbs. Although less attractive to felines than Nepeta cataria, it shares remarkable aromatic properties with it. Its name 'nervosa' refers to the very visible veining on its leaves, a distinctive characteristic of the species.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
