The Perfect Time to Plant Dahlias in Greater Victoria


Dahlias are a popular choice among gardeners in the Greater Victoria area, thanks to their stunning blooms, diverse colors, and varieties. Timing is crucial when planting dahlias to ensure a long blooming season. In this blog post, we’ll discuss the best time to plant dahlias in Greater Victoria and provide helpful tips to ensure a successful planting season. As avid dahlia enthusiasts, we at JN Landscaping Ltd. maintain own dahlia garden each year, which seems to get larger with each season.

  1. The Ideal Planting Time for Dahlias in Greater Victoria

In Greater Victoria, the optimal time to plant dahlias is in late spring, typically between late April and early May. The soil temperature should be consistently above 10°C (50°F) during this period. Planting dahlias too early, when the soil is still cold and wet, can lead to tuber rot or poor growth.

  1. Preparing Your Dahlias for Planting

Before planting your dahlias, ensure the tubers are healthy and free from signs of rot or damage. To give your dahlias a head start, consider starting letting them eye up and then potting them indoors in pots about 4 to 6 weeks before planting them outside. This allows the tubers to develop roots and shoots, giving them a head start and earlier blooms.

  1. Choosing the Right Location

Dahlias thrive in well-draining soil and require at least 6 hours of sunlight per day. When selecting a planting location, consider the specific sunlight and drainage requirements of your chosen dahlia variety. Provide enough space between plants to ensure adequate air circulation and prevent overcrowding, which can lead to disease and poor growth.

  1. Planting Your Dahlias

Dig a hole about 6 inches deep and slightly wider than the tuber. Place the tuber horizontally with the eye (the small bud on the tuber) facing upwards. Cover the tuber with soil, leaving the eye slightly exposed. Water the soil thoroughly and continue to water regularly throughout the growing season, ensuring the soil remains moist but not saturated.

  1. Staking and Supporting Dahlias

Some larger dahlia varieties may require staking to support their growth. Install stakes at the time of planting to avoid damaging the tubers later in the season. As the dahlias grow, gently tie the stems to the stakes using soft twine or plant ties, providing the necessary support without damaging the plants.


Potting up your dahlias early can an result in your dahlias blooming from July through to October.
