Fertilising a Catalpa bignonioides 'Aurea'
To maintain the striking foliage and robust growth of Catalpa bignonioides 'Aurea', fertilizing is an essential part of its care regimen. This species thrives with an annual application of a balanced, slow-release fertilizer formulated for trees and shrubs. Apply the fertilizer in early spring, as new growth begins to emerge, to support the vibrant yellow foliage that transitions to green as the season progresses. The nutrients will bolster the plant's flowering capability, ensuring a bountiful display of white blossoms in the summer months. It is important to follow manufacturer instructions for the correct dosage, evenly distributing the fertilizer around the base of the tree, while avoiding contact with the trunk. A thorough watering after application will help the soil absorb the nutrients, setting the stage for a season of lush growth.
