Description

Regarded as the showstoppers of the dahlia world, these plants produce large, lavish blooms accompanied by lush foliage that can serve as the centrepiece of any garden. These flowers command attention and are perfect for garden beds or sizeable pots. Their intricate petal patterns and vibrant colours render them adaptable for any garden design.

When planting dahlias in pots, choosing a pot with good drainage is important to prevent waterlogging. A pot at least 30cm in diameter is ideal for giving the tubers enough room to grow.

Successfully cultivating dahlias is very feasible in suitable climates. While dahlias prefer cooler climates, they can also thrive in temperate and tropical regions, depending on the variety. Generally, dahlia flowers are more likely to bloom in climates with mild frosts or without heavy frosts.

If you reside in one of Australia’s frost-prone regions, you can aid your dahlias’ growth by relocating them during winter and storing them in a dry area. For those in hot climates, it can be advantageous to plant dahlia tubers in a garden section that receives ample morning sunlight and afternoon shade.

While dahlias often thrive when left undisturbed for years, it’s advisable to lift and separate them every second winter, particularly if your soil tends to remain damp during winter, which can lead to tuber rot.

When lifting, take care to prevent the tubers from drying out completely. Covering them with soil or sawdust can help prevent this. When dividing your tubers, ensure that each division retains some of the old stem, as this is where new growth will emerge from.

In springtime, it’s advisable to remove the smaller side shoots, preserving only one central flower at the apex. This strategy fosters the optimal growth of the central flower, as it can thrive without the competition for resources from other budding flowers. Additionally, spring is an opportune moment to unearth dahlia tubers and separate them into individual units, making sure each possesses viable eyes, then patiently await their sprouting. Upon observing the emergence of a shoot, it’s time to plant them, and once six pairs of leaves have developed, trimming off the top bud is recommended.

For optimal results, stake the plants to ensure they grow upright.

Dahlias can be prone to pests like aphids and spider mites, and diseases such as powdery mildew. Natural methods, like introducing beneficial insects, can be effective. For severe infestations, a pesticide might be necessary. Always follow manufacturer guidelines if using chemicals and consider the impact on your garden’s ecosystem.

How to Plant

Plant the tuber around 10cm deep, with the growing tip a little under the soil surface facing up, and then water them in well. If you’re looking to plant a few of them, it is important that you are planting dahlia tubers at a density of around 60cm apart. Tall varieties will need staking and you can do this at planting time to minimise damage to the tubers.

Soil

Dahlia tubers flourish in well-drained, organic-rich, neutral, or alkaline soil. Adding lime to acidic soils can be highly beneficial. Ensure the soil maintains good drainage while retaining moisture for optimal dahlia growth.

Watering

Except in very dry conditions, water your dahlias lightly until the plants have grown to around 15cm high, as an excess of water can cause the tubers to rot before they’ve had an opportunity to grow.
Once your dahlias have reached over 15cm, it is important to keep the soil moderately moist, watering them once or twice a week. Be cautious not to over-water, as this can lead to rot. Wilted leaves often indicate under-watering.

Prunning

Dahlias thrive when regularly picked, so removing spent flowers will stimulate further blooming.
In cooler areas, mulch to protect from frost once plants become dormant. This will help extend their flowering season.

Fertilising

Dahlias benefit from regular feeding. Use a balanced, slow-release fertiliser at planting time and consider a liquid fertiliser every few weeks during the growing season.
