Fertilising a Carpinus betulus
To ensure a robust and vibrant Carpinus betulus hedge, fertilizing is a pivotal part of its maintenance. It is recommended to fertilize in early spring, before the onset of the growing season, and again in mid-summer to support its swift growth rate. An all-purpose, slow-release fertilizer is ideal, as it provides a steady supply of nutrients. When applying fertilizer, distribute evenly around the base of the hedge, taking care to avoid direct contact with the trunk to prevent any potential damage. Water thoroughly after fertilizing to help the nutrients penetrate the soil and reach the roots. This practice not only encourages dense foliage but also fortifies the plant against harsh winter conditions, particularly in areas within USDA zone 5a where it displays considerable winter hardiness.
