LEPTOSPERMUM S. KIWI

Planting Leptospermum scoparium ‘Kiwi’

Leptospermum scoparium ‘Kiwi’, commonly known as New Zealand Tea Tree, is an evergreen shrub admired for its fine, aromatic foliage and masses of small, colourful flowers. It is ideal for adding texture and vibrant seasonal interest to sunny borders, coastal gardens, or containers.

Choosing the right position

• Prefers full sun for best growth and flowering
• Requires a warm, sheltered location protected from cold winds
• Ideal for coastal gardens due to tolerance of salt-laden air
• Suitable for borders, gravel gardens, and patio containers
• Avoid exposed or frost-prone areas

Soil requirements

• Thrives in well-drained, acidic to neutral soil
• Prefers light, sandy or loamy soils
• Does not tolerate heavy or waterlogged conditions
• Avoid chalky soils, which may lead to poor growth
• Improve drainage by incorporating grit or horticultural sand

How to plant in the ground

• Dig a hole twice the width of the root ball and similar depth
• Loosen the soil at the base to aid root establishment
• Position the plant so the root ball is level with the soil surface
• Backfill with soil, firm gently, and water thoroughly
• Apply a light mulch, such as bark or gravel, to retain moisture

Planting in containers

• Choose a pot with good drainage holes
• Use a free-draining compost, such as ericaceous or multi-purpose with added grit
• Select a container slightly larger than the root ball
• Water well after planting and allow excess water to drain
• Place in a sunny, sheltered position

Ongoing Care and Maintenance

Leptospermum ‘Kiwi’ is relatively easy to maintain, provided it is grown in the right conditions.

Watering

• Water regularly during the first growing season to establish roots
• Once established, it is moderately drought tolerant
• Water during prolonged dry periods, especially in summer
• Container-grown plants require more frequent watering
• Avoid overwatering, particularly in cooler months

Feeding

• Apply a light, balanced fertiliser in spring
• Use an ericaceous feed if soil is not naturally acidic
• Container plants benefit from occasional liquid feeding during the growing season
• Avoid excessive feeding, which can encourage soft, weak growth

Pruning

• Lightly prune after flowering to maintain a neat shape
• Remove any dead, damaged, or crossing branches
• Avoid cutting back into old wood, as regrowth can be slow
• Regular light trimming encourages a bushier habit
• Use clean, sharp tools for best results

Mulching

• Apply a light mulch in spring to conserve moisture
• Bark or gravel mulch works well for this plant
• Helps suppress weeds and improve soil conditions
• Keep mulch away from the base of the plant

Seasonal Care and Common Issues

With the right care, Leptospermum ‘Kiwi’ will provide reliable colour and structure throughout the year.

Winter care

• Not fully hardy in colder climates and may require protection
• Protect from frost and cold, drying winds
• In colder areas, grow in containers that can be moved to shelter
• Use horticultural fleece during cold spells if planted outdoors
• Ensure excellent drainage to prevent winter root damage

Flowering and appearance

• Produces masses of small, colourful flowers in late spring to early summer
• Best flowering occurs in full sun
• Foliage remains evergreen and aromatic throughout the year
• Regular light pruning helps maintain a compact and tidy shape

Common problems

• Root rot can occur in poorly drained or waterlogged soil
• Leaf drop may result from cold stress or overwatering
• Poor flowering can be caused by insufficient sunlight
• Generally pest-free, though occasional aphids may appear
• Yellowing leaves may indicate unsuitable soil conditions

Leptospermum scoparium ‘Kiwi’ is a striking and versatile shrub that brings both texture and seasonal colour to the garden. Its fine foliage and profusion of flowers make it an excellent choice for sunny, sheltered positions. With well-drained soil, a warm location, and minimal maintenance, it will thrive and provide a vibrant display year after year.
