Care

Exposure

Install the field rose in full sun (at least 6 hours per day) for optimal flowering. Partial shade exposure is acceptable but may reduce flower production. Avoid overly windy areas that weaken the stems.

Watering

Water regularly during the first year to establish a good root system. Once established, this wild rose is tolerant of drought thanks to its deep roots. During intense heat periods, weekly watering is sufficient.

Soil

Prepare well-drained soil rich in organic matter. Adding compost at planting time promotes rooting. This rose adapts to slightly acidic to neutral soils and dislikes waterlogging.

Pruning

Prune in late winter (February-March) to maintain a balanced shape and remove dead wood. Light pruning after flowering encourages denser branching. Remove branches that cross or become too invasive.

Fertilizer

An application of compost or balanced fertilizer in spring is more than sufficient. This wild rose doesn't require intensive fertilization and thrives on natural soil nutrition well-supplied with organic matter.

Diseases and pests

The field rose is generally robust and little susceptible to disease. Watch for powdery mildew and aphids in warm, humid conditions. Good air circulation and removal of dead leaves reduce the risk of fungal problems.

Did you know?

Rosa agrestis, also called harsh eglantine, is a wild rose that has been a founding member of European flora since the Quaternary period. Once highly valued for rose essence extraction and used as a natural rootstock, it is a genetic ancestor of modern roses. Its hips (red fruits) offer genuine nutritional treasure and have long been valued in traditional herbalism.

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.
