What to do this April

Plant / sow

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.

Fertilise

Portuguese laurel has moderate water needs. Once established, it tolerates short dry spells, but young plants and hedges benefit from regular watering during prolonged dry weather in spring and summer. Water deeply rather than little and often, encouraging roots to grow down. In autumn and winter, natural rainfall is usually sufficient unless conditions are exceptionally dry. Feed in March or April with a balanced general-purpose fertiliser such as blood, fish and bone or a controlled-release granular feed, scattering it around the base of the plant and watering in if rain isn't forecast. A second, lighter feed in early summer can boost growth on young hedges, but established plants rarely need more than an annual spring application. Avoid high-nitrogen feeds late in the season, as they promote soft growth vulnerable to frost. Mulch annually in spring with garden compost, well-rotted manure, or bark chips to suppress weeds, conserve moisture, and improve soil structure. Keep mulch clear of the stem itself. Portuguese laurel is generally trouble-free. The most common problem is shot-hole disease (Stigmina carpophila), a fungal infection causing small brown spots that drop out, leaving holes in the leaves. Improve air circulation by thinning dense growth and clear up fallen leaves. Powdery mildew can occur in dry conditions; water at the base rather than overhead. Vine weevil larvae occasionally damage roots in container-grown plants. This evergreen is fully hardy in zones 7–9 and needs no special winter protection in temperate Europe, though young plants appreciate shelter from cold winds in their first year.
