Fertilising a Thuja occidentalis 'Excelsa'
To support the robust growth and enhance the lush greenery of Thuja 'Excelsa', fertilizing is an essential aspect of its care. An optimal fertilizing schedule involves applying a balanced, slow-release fertilizer in early spring, just before the onset of the growth period. This initial application should be complemented with a second feeding in mid-autumn to prepare the hedge for the winter months.
It's important to select a fertilizer that is formulated for evergreens to ensure the correct balance of nutrients that promote healthy foliage and root development. When applying, distribute the fertilizer evenly around the base of each plant, avoiding direct contact with the foliage to prevent burn. Water the area well after application to help the nutrients penetrate the soil.
