About Prickly heath
Gaultheria mucronata, commonly known as Prickly Heath or Chilean Wintergreen, is a medium-sized evergreen shrub native to Chile and Argentina, growing 0.5 to 1.5 meters tall. It is characterized by its small, spiny leaves and, most notably, by its showy, brightly colored berries (white, pink, red, or purple) that persist through autumn and winter. It is ideal for low hedges, borders, or as an understory plant in wild or Atlantic-inspired gardens, providing color and structure during the colder seasons.

Care tips
This plant prefers a location with partial shade or light shade, especially in warmer climates, and an acidic, well-drained, organic-rich substrate. Keep the soil consistently moist but avoid waterlogging, particularly during warmer months. A common mistake is planting it in alkaline soils, which can lead to chlorosis; ensure the soil pH is low (acidic).
How to save a dying Prickly heath

- What kills it
- Excessive heat, strong direct sun, dry or alkaline substrate, and lack of humidity. Does not tolerate lime in water.
- Can it be saved?
- Yes, if you act quickly. Good watering with acidic water and relocation to shade are often effective if damage is not too extensive.
