How to care for your Juniperus Hibernica

  • Light: Prefers full sun to partial shade. In areas with hot summers, it is best to provide some afternoon shade to protect the foliage from scorching.
  • Soil: This plant is adaptable to a wide range of soil types, but prefers well-draining soil. If your soil is heavy or poorly drained, amend it with compost or sand to improve its structure.
  • Watering: It is drought-tolerant and does not require frequent watering. Water it deeply and infrequently, and avoid overwatering which can lead to root rot.
  • Fertilisation: This plant is not a heavy feeder and does not need to be fertilised regularly. If you wish to fertilise, you can use a slow-release fertiliser once a year in early Spring.
  • Pruning: It is a slow-growing plant and does not require frequent pruning. If you need to control its size or shape, you can prune it after it finishes blooming, in late Spring or early Summer.
  • Winter Protection: It is hardy down to temperatures < -20˚C.  However, in very harsh winters, it may be beneficial to protect it with a layer of mulch or a Winter-proof covering.

By following these simple care tips, your Juniperus Hibernica will thrive and provide you with years of enjoyment in your garden.
