Fertilising a Sedum spectabile 'Brilliant'
To support the robust, upright growth habit and vibrant pink blooms of the species, a balanced approach to fertilizing is recommended. Ideally, apply a general-purpose fertilizer in early spring as the foliage begins to emerge, ensuring the plant is well-nourished leading into its growing season. This will help establish a strong foundation for growth and flowering in the following months.
The plant's moderate water needs should be considered when fertilizing, as over-watering can dilute the soil nutrients. Well-drained soil will help prevent this problem and maintain the necessary nutrient levels. An additional light feeding during the summer can be beneficial, especially if the plant is grown in a container where nutrients may be more quickly depleted. However, avoid late-season fertilization, as this can stimulate new growth that may be vulnerable to early frosts.
