Crepe myrtles are a fantastic choice for Australian gardens. Known for their long-lasting blooms and vibrant colors, these plants add serious style to any outdoor space. Lagerstroemia indica, as they’re also called, includes popular varieties like white crepe myrtle and crepe myrtle Natchez. They love the warm Aussie climate and are pretty easy to care for. Let’s dive into the basics of growing and looking after crepe myrtles so you can enjoy them in your garden.
The Different Types and Varieties of Crepe Myrtle
Crepe myrtle comes in a bunch of different shapes and sizes, from compact shrubs to tall, stately trees.
- There’s the classic Lagerstroemia indica, which comes in pink, red, and purple shades.
- Then there’s crepe myrtle Natchez (or Lagerstroemia Natchez), known for its stunning white flowers and smooth, attractive bark that adds interest year-round.
With so many options, it’s easy to find a variety that fits your space and style. Just think about the look you want and the amount of space you have, and you’re good to go.
Planting Crepe Myrtle in Open Ground
Getting the planting right is key if you want your crepe myrtle to thrive. Let’s go over the basics, from timing and soil type to picking the right spot.
When to Plant
Planting crepe myrtles in late winter or early spring is ideal. This timing lets the roots establish before the intense summer heat kicks in. Try to avoid planting in the peak of summer, as young plants can struggle in high temperatures.
Suitable Soil
Crepe myrtles do best in well-drained soil. If your soil is on the heavy clay side, mix in some compost or coarse sand to improve drainage. They’re pretty adaptable, but slightly acidic to neutral soil will keep them happiest.
Best Spot for Planting
Choose a location that gets lots of sunlight. Crepe myrtles need full sun to bloom well, so aim for at least six hours of direct light daily. Avoid planting them in shady areas, as this can lead to fewer blooms and leggy growth.
Planting Process
Dig a hole that’s about twice as wide as the root ball and only as deep as the plant itself. Pop your crepe myrtle in the hole, backfill with soil, and give it a good soak to help the roots settle in.
Taking Care of Crepe Myrtle
Once planted, crepe myrtles don’t need much fussing, but a little care goes a long way in keeping them healthy and looking great.
Watering
Water deeply once a week during the first growing season to help the roots establish. After that, crepe myrtles become pretty drought-tolerant and usually only need watering during long dry spells.
Fertilizing
Use a balanced, slow-release fertilizer in early spring. Avoid over-fertilizing, as this can cause lots of leafy growth at the expense of flowers. A single feeding each year should be enough.
Loosening
Loosen the soil around the base of the plant every so often to prevent compaction and improve airflow around the roots. Be gentle, though—crepe myrtles have shallow roots that can get damaged with aggressive digging.
Pruning
Pruning helps keep your crepe myrtle in shape and encourages blooms. In late winter, remove any dead branches and thin out any crowded areas. Just be careful not to overdo it, as heavy pruning can weaken the plant and reduce flowering.
Caring for Crepe Myrtle After Flowering
Once the flowering season is over, snip off any spent blooms to tidy up the plant. This also helps prevent seed production, allowing the plant to put its energy back into growth.
Ways to Propagate Crepe Myrtle
Crepe myrtles can be propagated using cuttings or seeds. Softwood cuttings taken in spring tend to work best. Just dip the cuttings in rooting hormone, place them in a mix of perlite and peat, and keep them moist until roots start to form.
Common Problems: Diseases and Pests
While crepe myrtles are generally tough, they can sometimes get powdery mildew, especially in humid areas. If you spot mildew, treat it with a fungicide or neem oil. Also, keep an eye out for aphids; they can cause a sooty mould on the leaves. A quick spray with insecticidal soap should take care of it.
Using Crepe Myrtle in Landscape Design
Crepe myrtles are super versatile in landscaping. They make great focal points as standalone trees or add colour to a mixed border. Dwarf varieties are perfect for smaller gardens or pots, while taller varieties like Natchez crepe myrtle are great for natural screens or even shade trees.
Wrapping Up
Growing crepe myrtles in Australia is a rewarding experience, especially if you give them a bit of attention to keep them happy. From picking the right spot to a little seasonal care, these stunning plants will reward you with beautiful blooms and year-round interest. With the right care, your crepe myrtles will thrive and become a standout feature in your garden for years to come.
