Care Notes

Rhododendron (Y) 'Caroline Allbrook' thrives in acidic, well-drained soil, preferably in partial or dappled shade, sheltered from harsh winds and intense afternoon sun. Water regularly, especially during dry spells and when establishing, ensuring the soil remains consistently moist but not waterlogged. Mulch annually with ericaceous compost or well-rotted bark chips to help retain moisture, suppress weeds, and maintain the necessary soil acidity. Deadhead spent flowers carefully to encourage more blooms and maintain a tidy appearance. Prune lightly after flowering to remove any damaged or unruly branches or to maintain a desired shape and size; avoid heavy pruning into old wood. Feed with a specific ericaceous fertiliser in early spring to support healthy growth and prolific flowering.
