Caragh Garden Notebook
Planting:
Plant in spring or autumn in well-prepared, well-drained soil. As an espalier, it works especially well against a wall or fence where the framework can be shown off to best effect.
Watering:
Water well after planting and during dry spells while it establishes. Once settled, it is fairly resilient.
Feeding:
A spring mulch of compost or well-rotted organic matter will help keep growth healthy.
Seasonal Care & Tidy-Up:
Light pruning may be needed to maintain the espalier shape and keep growth neat and controlled.
Pests & Problems:
Generally reliable and low maintenance when grown in the right position.
Design Notes:
Excellent for formal gardens, narrow spaces, courtyards and boundary planting. It brings a strong architectural line and evergreen structure, while still feeling elegant and understated.
