Why Grow Dahlias in Western Australia?
There’s something magical about dahlias, isn’t there? Their bold colours and intricate shapes bring a joyful energy to any space. Dahlias are well-suited to the Perth climate, especially if you’re in regions with warm summers and mild winters like ours.
Growing dahlias means you’re inviting a splash of elegance and cheer into your garden. Plus, they’re fantastic for cut flowers, perfect for brightening up your home or even for those special wedding bouquets we all adore. And if you’re like us, there’s nothing quite like the satisfaction of watching your own flowers bloom from tuber to full glory.
How to Grow Dahlias Successfully
Let’s get down to the nitty-gritty of growing these gorgeous flowers. Here’s a simple, step-by-step guide to help you get started:
Choose the Right Spot
Dahlias love sunshine! Pick a spot in your garden that gets at least 6 hours of direct sunlight daily. Good air circulation is also important to keep those pesky fungal diseases at bay.
Prepare the Soil
These flowers prefer well-draining soil rich in organic matter. Before planting, mix in compost or aged manure to give your dahlias a nutrient boost. If your soil is heavy clay, consider adding some sand or perlite to improve drainage.
Planting the Tubers
Plant your tubers about 10-15cm deep with the growing points facing up. Space them roughly 60cm apart to give each plant room to stretch out and grow. Water them well after planting to settle the soil.
Watering and Feeding
Keep the soil moist but not soggy. Overwatering can cause tuber rot, so a good balance is key. Feed your dahlias every 3-4 weeks with a balanced liquid fertiliser to encourage those big, beautiful blooms.
Staking for Support
Pam Howden dahlias can grow quite tall, so staking is a must. Use bamboo stakes or garden canes and tie the stems loosely with soft garden ties to keep them upright.
Deadheading and Maintenance
Regularly remove spent flowers to encourage continuous blooming. Keep an eye out for aphids and powdery mildew, and treat promptly if needed.
By following these steps, you’ll be well on your way to growing a stunning display of dahlias that will have your neighbours stopping by for a closer look!
Seasonal Tips for Perth Gardeners
Perth's climate can be a bit of a mixed bag, so timing and care are everything. Here’s how to tailor your dahlia growing routine to our local conditions:
Spring Planting
In most parts of Perth, spring is the perfect time to plant your tubers. The soil is warming up, and the risk of frost is low. This gives your dahlias a long growing season to shine.
Summer Care
Summer is showtime! Keep watering regularly, especially during dry spells. Mulching around the base helps retain moisture and keeps the roots cool.
Autumn Harvest
As the weather cools, dahlias will start to slow down. This is a great time to cut flowers for indoor arrangements or weddings. If you’re in a frost-prone area, dig up the tubers before the first frost and store them in a cool, dry place for replanting next season.
Winter Storage
Store your tubers in a paper bag or box with peat moss or sawdust. Keep them in a frost-free spot with good ventilation. This little bit of care ensures your dahlias come back strong year after year.

Tips for Using Dahlias in Your Garden and Events
Once you’ve got your dahlias growing beautifully, it’s time to think about how to showcase them:
Garden Design
Plant them in clusters for a bold statement or mix with other perennials for a more relaxed, cottage garden feel. Their height and colour make them perfect as a backdrop or focal point.
Cut Flower Arrangements
Dahlias last well in a vase. Cut stems early in the morning or late afternoon, and place them in fresh water immediately. Change the water every couple of days to keep them looking fresh.
Wedding Bouquets and Decor
Their dramatic blooms are perfect for bridal bouquets, table centrepieces, and ceremony arches. Pair with greenery and softer blooms for a balanced look.
Community and Sharing
Share your blooms with neighbours or local flower swaps. It’s a wonderful way to spread the joy and connect with fellow flower lovers.
Growing and using dahlias is not just about the flowers themselves, but about the happiness and community they help cultivate. We’re excited to see how you’ll bring these gorgeous blooms into your life!
