Dahlia Tubers

There’s no flower more stunning than a dahlia. The perfect flower to bloom through summer, a dahlia tuber can help cover up the bare spots in your flower garden. Dahlias are well-suited for Australian summers, as they thrive in hot, dry conditions. As drought-tolerant plants, they have a prolonged flowering period and are easy to grow. 


With both dahlia seeds and tubers at Mr Fothergill's, you can find the perfect summer-flowering bulbs for your garden.

When to Grow Dahlia Tubers

Dahlia tubers are recommended to be grown when spring starts. Specifically, they should be planted after the last frost, as this time provides the ideal temperature for them to get started in your garden.

With dahlia flowers coping well in hotter climates, you can plant them in spring and enjoy a multitude of summer blooms to keep your garden looking at its best.

How to Grow Dahlia Tubers

While you can grow dahlias from flower seeds, they are most commonly grown from dahlia tubers. They love the sun, so they will need to be grown in a sunny spot in your growing space. However, they may need some protection on particularly hot or windy days.

As they grow, they should be regularly watered and fed with a liquid fertiliser to ensure they have all the nutrients they need to produce their beautiful blooms. They’ll also benefit from their soil being mulched to prevent weeds from growing and to keep the soil cool and moist. Dahlias can grow quite tall, so provide them with support in the form of a stake if needed to prevent their stems from breaking.

For further advice on how to grow dahlias from tubers and seeds, our in-depth guide tells you all you need to know to choose the right dahlias for your needs and our best tips to grow these summer favourites at home.

Getting Your Garden Started in Spring

Dahlias are among some of the best spring-planting flowers, though many other flower plants will look great alongside them if you’re looking to grow your garden into a show-stopping paradise! Some of our favourite flower seeds to sow in spring are marigold seeds, which not only complement each other’s bright colours but also repel pests that could attack your dahlias.
