Portuguese Laurel in September: monthly care

Portuguese laurel thrives in full sun or partial shade and tolerates a wide range of soils, including loam, clay, chalk, and sand. The key is good drainage; waterlogged ground will cause root problems. Before planting, dig over the area and work in some well-rotted compost or manure to improve soil structure, especially if your ground is heavy clay or very sandy. Plant container-grown specimens in March, April, or May for spring planting, or in September and October for autumn. Autumn planting is often preferable because the soil is still warm and autumn rain helps establishment, but spring works well too if you can water reliably through the first summer. Dig a hole roughly twice the width of the root ball and the same depth. Remove the plant from its pot, gently tease out any circling roots, and set it so the top of the root ball is level with the surrounding soil. Backfill with the excavated soil, firming gently as you go to eliminate air pockets. Space plants 50 cm apart if you're creating a hedge; for a specimen shrub, allow at least 100–150 cm from other plants to accommodate the mature spread. Water thoroughly after planting, even if the soil feels damp, to settle roots in. Apply a 5–7 cm layer of mulch around the base, keeping it a few centimetres clear of the stem to prevent rot. Stake only if planting a tall, top-heavy specimen in an exposed spot. Water regularly for the first growing season until the roots are established.

Portuguese laurel is naturally dense and responds very well to pruning, making it ideal for formal hedges and topiary. The main pruning window is June, after the spring flush of growth has hardened off, and again in September if needed to tidy up or maintain shape. Avoid pruning during frosty weather or in late autumn, as new soft growth won't harden before winter. For hedges, use sharp hedge shears or a hedge trimmer to cut back new growth by about half, maintaining a slightly tapered profile (narrower at the top) to ensure light reaches the lower branches. This encourages dense, even growth from top to bottom. If you're shaping a specimen shrub or topiary, prune to the desired outline, cutting just above a leaf node to encourage branching. Portuguese laurel tolerates hard renovation pruning if an old hedge has become leggy or overgrown. In late March or early April, you can cut back into older wood—even quite severely—and it will usually regenerate from dormant buds. Spread hard renovation over two or three years if you're nervous: tackle one side or section at a time. Remove any dead, damaged, or diseased branches whenever you spot them. Also cut out any plain green shoots that appear on variegated cultivars. Use clean, sharp secateurs for individual stems and loppers for thicker branches. Portuguese laurel doesn't require pruning to flower, but regular trimming will reduce or remove the small white flower clusters that appear in spring and early summer.
