PROSTANTHERA CUNEATA

Planting Prostanthera cuneata (Alpine Mint Bush)

Prostanthera cuneata is a compact, evergreen shrub known for its small, aromatic leaves and masses of pale mauve to white flowers in late spring and early summer. It is well suited to borders, rockeries, and sheltered gardens, bringing both fragrance and delicate colour.

Choosing the right position

• Prefers full sun to light partial shade
• Best flowering occurs in a warm, sunny position
• Ideal for borders, rock gardens, and containers
• Suitable for sheltered gardens with good air circulation
• Protect from cold winds and exposed conditions

Soil requirements

• Thrives in well-drained soil
• Prefers light, sandy or loamy soils
• Tolerates slightly acidic to neutral conditions
• Does not tolerate heavy, waterlogged soil
• Improve drainage with grit or sand if needed

How to plant

• Dig a hole twice the width of the root ball and similar depth
• Position the plant so the root ball sits level with the soil surface
• Backfill with soil and firm gently
• Water thoroughly after planting
• Space plants around 50–70cm apart
• Apply a light mulch to retain moisture

Planting in containers

• Use a pot with good drainage holes
• Fill with a free-draining compost mix
• Choose a container slightly larger than the root ball
• Water well after planting
• Place in a sunny, sheltered position

Ongoing Care and Maintenance

Prostanthera cuneata is relatively low maintenance but benefits from careful watering and light pruning to maintain its shape.

Watering

• Water regularly during the first growing season
• Keep soil lightly moist but not wet
• Once established, it is moderately drought tolerant
• Container plants require more frequent watering
• Avoid waterlogging, especially in winter

Feeding

• Apply a light, balanced fertiliser in spring
• Avoid excessive feeding, which can lead to soft growth
• Mulch annually with organic matter
• Container plants may benefit from occasional liquid feeding

Pruning

• Lightly trim after flowering to maintain shape
• Remove any dead or damaged growth
• Avoid hard pruning into old wood
• Regular trimming encourages a bushy habit
• Keep the plant compact and tidy

Mulching

• Apply a light organic mulch in spring
• Helps retain moisture and suppress weeds
• Improves soil structure over time
• Keep mulch away from the base of the plant
