Troubleshooting
Plant is not growing well.
Ensure the plant is in well-draining soil and receives adequate sunlight. Check for waterlogged conditions or insufficient watering during establishment.
Yellowing leaves.
This can be due to overwatering, poor drainage, or nutrient deficiency. Adjust watering schedule and ensure good soil aeration. A spring feed with a balanced fertilizer might help if the soil is poor.
Reduced flowering or berrying.
Ensure the plant is receiving enough sunlight. Pruning too late in the season can remove flower and berry buds.
Pests like aphids appear.
A strong jet of water can often dislodge aphids. For severe infestations, consider using an insecticidal soap, applying according to product instructions.

Setup, Compatibility & Care
Planting:
- Choose a sunny to partially shaded location with well-draining soil.
- Dig a hole twice the width of the root ball and of similar depth.
- Gently remove the plant from its container, taking care with the spines.
- Place the plant in the hole, ensuring the top of the root ball is level with the soil surface.
- Backfill the hole with soil, firming gently around the base.
- Water thoroughly after planting.
Compatibility:
This shrub is compatible with most garden soils. It pairs well with contrasting foliage colours like dark-leaved shrubs or silver-leaved perennials. Avoid planting in overly waterlogged conditions.
Care:
- Watering: Water regularly during the first growing season to help it establish. Once established, it is relatively drought-tolerant.
- Pruning: Prune in late winter or early spring to remove any dead, damaged, or crossing branches. If using as ground cover, light trimming can maintain a neat appearance. Wear gloves and protective clothing due to spines.
- Feeding: Generally, no feeding is required. If soil is poor, a light mulch of compost in spring can be beneficial.
