How to establish your Rhododendron Horizon Monarch?

Rhododendron Horizon Monarch performs best in a sheltered position with morning sun or dappled shade. Like most rhododendrons, it thrives in fertile, acidic soil that retains moisture while draining freely.

Mulching around the root zone helps keep roots cool and conserves moisture during warmer months. Avoid planting in hot afternoon sun or areas with poor drainage.

How to maintain your Rhododendron Horizon Monarch once established?

Watering

Keep soil consistently moist during establishment. Once established, Rhododendron Horizon Monarch is reasonably drought tolerant but benefits from watering during extended dry periods.

Feeding

Apply a fertiliser formulated for rhododendrons, azaleas, or acid-loving plants in early spring to encourage healthy growth and abundant flowering.

Pruning

Very little pruning is required. Remove spent flower trusses after flowering to encourage stronger growth and improved flowering the following season. Remove any damaged or dead branches as needed.

Mulching

Apply a layer of organic mulch such as bark, leaf mould, or compost annually to help maintain soil moisture and improve soil health.
