Fertilising a Euphorbia × martini
For optimal health and vibrant flowering, Euphorbia × martini requires fertilization at key stages of its growth. As this species is evergreen and maintains its foliage year-round, it benefits from a slow-release fertilizer applied in early spring. This initial feeding will bolster the plant's energy reserves as it enters its peak flowering months from April to July.
Choose a balanced fertilizer formulated for use on flowering shrubs or perennials to ensure a well-rounded nutrient profile. A second application can be applied in late summer to sustain the plant's needs as it continues to display its green, yellow, and red blooms.
Be sure to water the plant after fertilizing to help integrate the nutrients into the soil and reduce any potential stress on the root system. Proper fertilization will not only enhance the Euphorbia × martini's growth and flowering but will also support its resilience in a Mediterranean range of conditions.
