Fertilising a Magnolia stellata 'Rosea'
To ensure the spectacular spring blossoms for which this shrub is renowned, a balanced approach to fertilizing is key. For optimal growth and flower development, apply a complete, slow-release fertilizer designed for woody ornamentals early in the growing season. The best time to administer this is around the emergence of new foliage, typically in late winter to early spring before flowering begins.
A second application in late spring can help sustain the plant's energy needs throughout the growing season. Be cautious not to over-fertilize, as an excess can do more harm than good, potentially affecting the plant's blooming potential. Always follow the recommended dosage on the fertilizer packaging, and apply it to the soil around the base of the plant, avoiding direct contact with the trunk and lower branches to prevent any risk of burn.
