Culture

Cultivating Nepeta x faassenii ‘Select Blue’ successfully requires an understanding of its specific cultural requirements, including water, sunlight, fertilizer, and soil conditions. By ensuring that these needs are met, you can optimize the health and vigor of the plant, thereby enhancing its ornamental and functional value in your garden.

Water

Nepeta x faassenii ‘Select Blue’ is known for its tolerance to drought conditions, making it a suitable choice for water-wise gardening. While established plants are relatively resilient and can withstand dry spells, it is important to provide adequate moisture during the initial establishment phase and in prolonged periods of drought. Following a watering schedule that allows the soil to dry out slightly between waterings is generally recommended. Overly wet soil can lead to root rot and other issues, so it’s crucial to achieve a balance that promotes healthy growth without waterlogging.

Sunlight

In order to thrive and produce an abundance of vibrant blooms, Nepeta x faassenii ‘Select Blue’ requires full sun exposure. This typically translates to at least 6 hours of direct sunlight per day. Adequate sunlight not only promotes flowering but also contributes to the plant’s overall vigor and resistance to diseases. When selecting a planting location, be sure to choose a spot that receives ample sunlight, especially during the peak growing season.

Fertilizer

Nepeta x faassenii ‘Select Blue’ is considered a relatively low-maintenance plant when it comes to fertilization. In most cases, it can thrive in average to poor soil without the need for frequent feeding. However, if the plant displays signs of nutrient deficiencies or if you wish to encourage more robust growth and flowering, you can apply a balanced, slow-release fertilizer in early spring. Be sure to follow the manufacturer’s recommendations regarding application rates and methods to prevent over-fertilization, which can lead to excessive foliage at the expense of flowers.

Soil

The ideal soil for Nepeta x faassenii ‘Select Blue’ is well-drained, moderately fertile, and slightly alkaline to neutral in pH. This species is not particularly demanding in terms of soil quality and can adapt to various soil types, as long as water stagnation is avoided. Amending the planting site with organic matter such as compost or well-rotted manure can improve soil structure and fertility, benefitting the overall health and performance of the plant.

Pruning

Pruning is an essential aspect of maintaining Nepeta x faassenii ‘Select Blue’ and promoting repeat flowering, preventing self-seeding, and managing the plant’s overall appearance. Understanding the appropriate timing and techniques for pruning is crucial to ensure that the plant remains healthy and visually appealing throughout the growing season.

It is recommended to prune Nepeta x faassenii ‘Select Blue’ after the first flush of flowering begins to fade, usually around mid-summer. Using clean and sharp pruning shears, you can trim back the spent flower spikes and remove any straggly or leggy growth to encourage a more compact and tidy appearance. This practice often stimulates a second wave of blooms, extending the overall flowering period and enhancing the plant’s ornamental value.

In addition to regular deadheading and shaping, Nepeta x faassenii ‘Select Blue’ may benefit from rejuvenation pruning every few years. This involves cutting back the plant by around half of its height in early spring to promote fresh growth and rejuvenate the overall vigor of the plant. Division of mature clumps can also be considered during this time to prevent overcrowding and maintain the plant’s vitality.

Propagation

Propagating Nepeta x faassenii ‘Select Blue’ can be achieved through several methods, including division, stem cuttings, and seed sowing. Each approach has its own set of advantages and considerations, allowing you to choose the most suitable method based on your preferences and the availability of plant material.

• Division: Established clumps of Nepeta x faassenii ‘Select Blue’ can be divided every few years, typically in early spring, to rejuvenate the plant and create new stock. Dig up the entire clump and carefully separate it into smaller sections, ensuring that each division has a good amount of roots and healthy growth points. Replant the divisions in prepared soil, water thoroughly, and provide appropriate care to support their establishment.

• Stem Cuttings: Taking stem cuttings from healthy, non-flowering shoots is a reliable way to propagate Nepeta x faassenii ‘Select Blue’ and produce genetically identical offspring. Select a 4-6 inch stem tip with several sets of leaves and remove the lower set of leaves to expose the nodes. Plant the cutting in a well-draining rooting medium, maintain adequate moisture, and provide warmth and indirect light to encourage root development. Once rooted, the new plants can be potted up and gradually acclimated to outdoor conditions.

• Seed Sowing: Collecting and sowing seeds is an option for propagating Nepeta x faassenii ‘Select Blue,’ although it may result in some variation in the offspring due to genetic recombination. Gather mature seeds from the spent flower spikes and sow them in prepared soil in early spring or late summer. Keep the soil consistently moist and provide sufficient warmth and light for germination. Once the seedlings have developed several sets of true leaves, they can be transplanted to their permanent locations.

Container Popularity

The compact and bushy growth habit of Nepeta x faassenii ‘Select Blue’ makes it well-suited for container cultivation, offering an attractive and versatile option for various outdoor and indoor uses. Whether displayed individually in decorative pots or integrated into mixed containers and hanging baskets, this plant adds a touch of elegance and color to any setting.

Container Common Diseases

While Nepeta x faassenii ‘Select Blue’ is relatively resistant to many common pests and diseases, certain issues may arise, particularly when the plant is grown in containers. The confined space and limited soil volume in containers can exacerbate environmental stress and create conditions conducive to specific problems. One of the common diseases that may affect this plant in containers is powdery mildew, a fungal infection characterized by a white, powdery growth on the leaves and stems.

Disease Diagnosis

Diagnosing diseases in Nepeta x faassenii ‘Select Blue’ grown in containers involves careful observation of the plant’s symptoms and a thorough assessment of the growing environment. If you notice the characteristic signs of powdery mildew, such as the powdery white coating on the foliage and a gradual decline in plant health, you can take appropriate measures to address the issue and prevent its further spread. Prompt action, such as adjusting watering practices, improving air circulation, and using targeted fungicidal treatments, can help manage the disease and protect the plant from severe damage.

Common Pests

In addition to diseases, Nepeta x faassenii ‘Select Blue’ may encounter some common pest problems, particularly when grown in containers or in close proximity to other susceptible plants. Pests such as aphids, spider mites, and whiteflies can occasionally target this species, feeding on the tender foliage and causing visible damage. Regular monitoring and early intervention are key to preventing pest infestations and maintaining the plant’s health and vitality.
