Fertilising a Nandina domestica 'Firepower'
To encourage the vibrant foliage and robust growth that Nandina domestica 'Firepower' is known for, appropriate fertilization is key. Fertilize this species in early spring to kick-start the growing season. A balanced, slow-release fertilizer applied once a year is typically sufficient to meet the nutritional needs of the plant. Ensure the granules are spread evenly at the base of the shrub, avoiding direct contact with the stems and foliage to prevent burn.
Due to its evergreen nature, the shrub retains its foliage year-round, displaying an array of colors from green and red to stunning autumnal hues. The timely application of fertilizer supports this color transition and contributes to the overall health and vigor of the plant, which is especially important as it prepares to flower in the summer months.
