Introducing Crepe Myrtle Acoma: A Bunnings Favourite
If you’re hunting for a stunning, low-maintenance tree that fits snugly into Aussie backyards, the Crepe Myrtle Acoma (Lagerstroemia indica ‘Acoma’) from Bunnings is a top contender. This compact hybrid reaches just 3-4 metres tall and wide, making it perfect for small gardens, courtyards, or as a feature in pots. Its masses of crinkly white flowers in summer, combined with vibrant orange-red autumn foliage and attractive exfoliating bark, deliver year-round appeal.
Native to the southern US but thriving in Australia’s warm climates, Acoma is bred for disease resistance and vigour. You’ll find tubestock or advanced sizes at Bunnings warehouses across the country, often priced affordably from around $15 for young plants. It’s a smart buy for beginner gardeners or those seeking that classic crepe myrtle look without the size of larger varieties.
Why Crepe Myrtle Acoma Suits Australian Gardens
Australia’s diverse climates – from subtropical Queensland to temperate Victoria – make plant selection tricky, but Acoma shines. It’s rated for USDA zones 7-9, translating to Australian hardiness zones 8-10. It handles light frosts down to -10°C once established, ideal for coastal NSW, QLD, and protected spots in VIC and SA.
Key advantages:
- Drought tolerance: Survives dry spells common in Aussie summers; water weekly for the first year, then sparingly.
- Heat lover: Copes with 40°C+ days, unlike fussier natives.
- Urban tough: Pollution-resistant, great for Sydney suburbs or Melbourne streets.
- Small footprint: Multi-stemmed habit suits 2-3 metre spaces, no overshadowing the veggie patch.
In trials by Australian nurseries, Acoma outperforms older varieties in powdery mildew resistance, a common crepe myrtle woe in humid areas like Brisbane.
Planting Crepe Myrtle Acoma from Bunnings
Timing is key: Plant in autumn or early spring to dodge summer heat. Bunnings stock arrives in these seasons, so grab one with healthy roots and no leaf scorch.
Site Selection
Choose full sun – at least 6 hours daily – for prolific blooms. It tolerates light shade but flowers less. Well-drained soil is non-negotiable; crepe myrtles hate wet feet, a risk in clay-heavy Aussie soils.
Preparation and Planting Steps
- Dig the hole: Twice as wide as the pot, same depth as root ball (about 30-40cm for tubestock).
- Soil prep: Mix in 20-30% compost or cow manure. Add gypsum (1 handful per square metre) for heavy clays.
- Planting: Tease out circling roots, position so graft union (if present) sits 5cm above soil. Backfill, firm gently.
- Spacing: 2.5-3 metres from structures or other plants.
- Mulch: 5-7cm layer of pine bark or sugar cane around the base, keeping it 10cm from trunk to prevent rot.
Water deeply (20-30L) post-planting. For pots, use a 50-60cm diameter container with potting mix; elevate for drainage.
Ongoing Care for Thriving Acoma
Acoma is low-fuss, but these tips ensure bumper flowers.
Watering
Establish with 25-40L weekly for 6-12 months. Mature plants need 20L fortnightly in dry periods. Use drip irrigation in hot zones like Perth.
Fertilising
Apply a native or rose fertiliser (low phosphorus, e.g. NPK 12:4:8) in early spring and after flowering. Avoid high-nitrogen feeds to prevent weak growth. Yates Thrifty Garden range at Bunnings works well.
Pruning Essentials
Crepe myrtles respond brilliantly to pruning – don’t skip it!
- Timing: Late winter (July-August) before bud swell.
- Technique: Remove suckers at base, thin crossing branches. Tip-prune to outward buds for shape. For multi-stem, cut back to 30-50cm stumps annually for bushier form.
- Avoid: ‘Topping’ – it ruins natural shape and invites pests.
Expect 20-30cm annual growth.
Pests and Diseases
Mostly trouble-free, but watch for:
- Aphids/scale: Hose off or use eco-oil (Bunnings staple).
- Powdery mildew: Rare in Acoma; ensure airflow and avoid overhead watering.
- White lace bugs: Spray with pyrethrum if spotted in humid areas.
In wet summers (e.g. northern NSW), apply copper fungicide preventatively.
Design Ideas and Companions
Acoma’s white blooms pair beautifully with:
- Underplantings: Lomandra hystrix, Westringia, or dianellas for Aussie natives.
- Neighbours: Lavender, salvias, or agastache for pollinator magnets.
- Pots: Group three in a courtyard for screen; add grasses like Carex for contrast.
Use as a street tree alternative in narrow verge plantings. In QLD poolsides, its non-invasive roots won’t crack pavers.
Autumn colour rivals maples – plant near seating for fiery display.
