Fertilising a Agastache 'Blue Fortune'
To ensure the robust growth and vibrant flowering of Agastache 'Blue Fortune', fertilization should be approached with care. Apply a balanced, slow-release fertilizer early in the spring as new growth appears, providing a steady supply of nutrients throughout the growing season. A second application can be beneficial during the midsummer to support the prolonged blooming period that extends from June to September.
When applying fertilizer, distribute it evenly around the base of the plant, taking care to avoid direct contact with the foliage and stems to prevent any potential damage. Watering the plant after fertilizing helps to integrate the nutrients into the soil, allowing for optimal uptake by the roots. This practice will not only promote the health and vigor of Agastache 'Blue Fortune' but also enhance its aromatic foliage and striking blue to purple floral display.
