Expert tips
The key tip
Myrtle hates waterlogging: plant it in very well-draining soil, even gravelly. Light pruning after flowering keeps it shapely and encourages branching.
The common mistake
Watering too regularly during cold periods causes collar rot or root rot—way worse than a few weeks of dryness.
The pro's trick
Mix gravel or pumice into your planting soil; this extra drainage cuts watering in half.
Care
Watering
Common myrtle appreciates moderate watering during the growing season (spring-summer). Let the soil dry slightly between waterings. Once established, this shrub is very drought-tolerant and requires little water. In winter, drastically reduce watering.
Exposure
Place myrtle in full sun to optimize flowering and foliage density. It tolerates hot, sunny locations, even those exposed to sea winds. Partial shade is possible but will slightly compromise flowering.
Pruning
Prune lightly after flowering (August) to maintain a compact, bushy shape. Remove dead or crossing branches. Myrtle responds well to regular pruning and can be trained into formal shapes. Avoid severe pruning in winter.
Fertilizer
Apply balanced fertilizer in spring and early summer, once or twice monthly. A well-established plant in good soil needs little amendment. In containers, fertilizer is more important to support growth and flowering.
Soil and compost
Myrtle prefers well-drained, slightly chalky or neutral soil. In pots, use a light mixture (potting soil, pumice, sand). Avoid overly wet or compacted soils that promote root rot. Good drainage is essential.
Diseases and pests
Myrtle is generally robust. Watch for mealybugs and spider mites in hot, dry conditions. Excess moisture can cause leaf spots or root rot. Ensure good air circulation and avoid wetting the foliage when watering.
Did you know?
Myrtle is a symbol of love and purity in the Mediterranean basin since antiquity: the Romans dedicated it to Venus, and the Greeks associated it with fertility. Its leaves, flowers, and aromatic blue-black berries have long been used in Mediterranean cuisine, perfumery, and traditional medicine.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
