Fertilising a Prunus laurocerasus 'Caucasica'
For optimal health and growth, fertilizing Prunus 'Caucasica' is best done in the early spring and again in mid-summer. An all-purpose, slow-release fertilizer is ideal for this species, providing a steady supply of nutrients throughout its active growth periods. When applying fertilizer, ensure that it is evenly distributed around the base of the hedge, avoiding direct contact with the trunk and lower branches to prevent potential damage. Water deeply after fertilizing to help the nutrients penetrate the soil and reach the root ball.
Regular feeding of this evergreen helps maintain its lush, green foliage and supports its robust growth rate, making it an excellent choice for a quickly obscuring, visually dense hedge. Proper fertilization also enhances the plant's winter hardiness, enabling it to withstand the chill of USDA zone 6a.
