Expert tips
The key tip
Heather thrives in acidic, light, well-draining soil; avoid chalky and heavy soils. Water during dry summers without waterlogging.
The common mistake
Planting in chalky soil causes chlorosis, poor growth, and progressive decline.
The pro's trick
Before planting, dig a large hole and replace some of the soil with acidic, draining substrate.
Seasonal watch
In dry autumn, keep the soil slightly moist during flowering.
Care
Exposure
Plant wandering heath in full sun for optimal flowering and a compact shape. It also tolerates light part shade, but will flower less abundantly. An airy location promotes the plant's overall health.
Watering
Water regularly after planting until the root system is established (6–8 weeks). Once settled, wandering heath is low in water demand and tolerates temporary drought. Avoid chalky water and stagnant moisture, which encourage decline.
Soil and drainage
Choose acidic, light and well-drained soil. Enrich planting soil with peat or leaf compost if your soil is chalky or heavy. Good drainage is essential to prevent root rot.
Pruning and maintenance
Prune lightly after flowering (November–December) to maintain a compact, bushy shape. Remove dead or damaged branches in spring. Avoid harsh pruning, which compromises the plant's natural structure.
Fertilisation
No fertiliser is needed. Wandering heath thrives on poor soils. Excess nutrients, particularly nitrogen, slow flowering and encourage unbalanced foliage.
Pests and diseases
Wandering heath is relatively unaffected by major pests. Watch for powdery mildew if humidity is excessive and air circulation is poor. Root rot is the main risk in wet or compacted soil.
Did you know?
Wandering heath owes its scientific name 'vagans' to its sparse and fragmented distribution around the western Mediterranean. In Brittany, it grows wild on acidic coastal heathland, where it mingles with its more common relatives. This heath is a living symbol of Heronian flora and a true treasure for temperate-climate Mediterranean plant enthusiasts.
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.
