Fertilising a Geranium 'Rozanne'
To ensure the Geranium 'Rozanne' thrives and produces its stunning blue flowers from spring through fall, appropriate fertilization is paramount. Commence with an application of a balanced, slow-release fertilizer in early spring as new growth appears. A second application should be made during midsummer to support the prolonged flowering period. It is crucial to follow manufacturer instructions to avoid over-fertilization, which can lead to excessive foliage at the expense of blooms.
Incorporating compost or a well-decomposed organic matter into the soil at the beginning of the growing season can also promote vigorous growth and flowering. Always water thoroughly after fertilizing to help distribute nutrients evenly in the soil and to minimize the potential for root burn. Such care will ensure this hardy perennial remains a showpiece in the garden.
