Description
Pompon Dahlias are a charming and distinctive variety of dahlias, celebrated for their small, spherical blooms and intricate petal structure. The fully reflexed petals give the flowers a smooth, polished look, resembling brightly coloured golf balls or small pom-poms. Their blooms can reach up to 7.5 cm in diameter.
Their sturdy stems make them weather-resistant and less prone to flopping over compared to some larger dahlia varieties. This makes them ideal for any garden setting, particularly those with limited space. They are also a versatile choice for patios, balconies, and small garden spaces.
When planting dahlias in pots, it’s important to choose a pot with good drainage to prevent waterlogging. They should be spaced about 30 cm apart to allow enough room for growth and adequate air circulation.
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. It is best to store them in a cool, dry place until the following spring.
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.
While dahlia tubers may require an initial investment, they can prove to be a worthwhile one as they are easily multiplied.
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.
