Basic Care

Best planted in a sunny position in a well drained soil. In areas of poor drainage, try hilling up the garden bed a little before planting.

Water in well after planting and water occasionally through the first summer. Mulch around the plant to maintain a cool root run.

Like all Grevilleas, Honey Gem does not like to have its roots disturbed, so avoid digging around the base of the plant.

Soil and Drainage Requirements

Free-draining soil is key to success with Grevillea ‘Honey Gem’. Sandy or loamy soils are ideal, allowing water to move through easily.

If planting in heavier soils, improving drainage before planting is recommended. This may include adding coarse material or building up the planting area.

Avoid wet or waterlogged conditions, as grevilleas are sensitive to excess moisture around the roots.

Climate Suitability and Frost Tolerance

Grevillea ‘Honey Gem’ grows well across a wide range of Australian climates, particularly in warm temperate and subtropical regions.

It thrives in full sun and benefits from a position protected from strong winds. While established plants can tolerate light frost, younger plants may be affected by colder conditions.

In cooler regions, a sheltered, sunny location will help support healthy growth and flowering.

Watering Requirements

Water well after planting and continue regular watering through the first summer while the plant establishes.

Once established, Grevillea ‘Honey Gem’ is reasonably drought tolerant and generally requires only occasional deep watering during extended dry periods.

Container-grown plants will need more frequent watering, especially during warmer weather.

Care and Maintenance

This is a relatively low-maintenance plant once established. Avoid disturbing the soil around the base, as grevilleas have sensitive root systems.

Mulching will help retain soil moisture and regulate temperature around the roots. Fertiliser is rarely needed, but if applied, use a low-phosphorus product suitable for native plants.

Pruning Grevillea ‘Honey Gem’

Pruning will help maintain a dense shape and encourage more prolific flowering.

Begin light pruning from a young age to control size
Remove spent flowers to promote new growth
Carry out more substantial pruning after flowering if required

Regular pruning will keep the plant bushy and bring the flowers down to a more visible level.

Landscaping Uses

Grevillea ‘Honey Gem’ is a versatile plant suited to a range of landscape applications.

It works well as a tall screening or hedging plant, as a background feature in garden beds, or as a standalone specimen in larger spaces.
