Radiance

Since Radiance dahlias are not hardy, we don’t recommend leaving them in the ground over winter. Dahlias are tender perennials that prefer warm temperatures and well-drained soil. If left in the ground during winter, the tubers are likely to rot or freeze, which could kill the plant.

Instead, it is best to dig up the tubers after the first frost and store them in a cool, dry place until the following spring. This will help ensure that the tubers remain healthy and produce beautiful blooms year after year.

But, if you live in an area with warmer temperatures and mild winters, then you’ll be fine leaving Radiance dahlias in the ground over winter.

To keep Radiance Dahlias blooming, it is important to follow some key steps. First, make sure the soil is well-draining and rich in organic matter. Dahlias also require full sun to thrive, so plant them in an area that receives at least 6-8 hours of sunlight per day.

Regular watering is essential, particularly during hot and dry weather. However, avoid overwatering as this can lead to root rot. Deadheading spent blooms is also important to encourage continuous flowering.

Fertilize dahlias every 2-4 weeks with a balanced fertilizer to promote healthy growth and vibrant blooms. Finally, protect the plants from pests and diseases by regularly inspecting them and treating any issues promptly. With proper care, Radiance Dahlias will continue to bloom and add vibrant color to your garden.

Radiance dahlias can be grown both in pots and in the ground, depending on the growing conditions and the gardener's preferences. When planted in the ground, dahlias tend to have a more extensive root system and can reach their full growth potential, producing larger and more abundant blooms.

However, if the soil in your garden is not suitable, or if you have limited space, growing dahlias in pots can be a great option. Potted dahlias require regular watering, feeding, and a well-draining potting mix. Regardless of the growing method, it is essential to provide adequate sun exposure, as dahlias thrive in full sun conditions.

We recommend a balanced fertilizer with an almost equal mix of NPK, such as a ratio of 10-20-20 or 5-10-10. NPK is a mix of nitrogen, phosphorus and potassium. Use this right after you plant the dahlias and then every 2-4 weeks.

It's important to follow the manufacturer's instructions for application rates and timing, as over-fertilizing can lead to burned roots and damaged plants. Additionally, a slow-release fertilizer can be beneficial as it will provide a steady supply of nutrients to the plant over time.

Finally, it's worth noting that dahlias are heavy feeders and may benefit from regular applications of organic matter such as compost or aged manure to improve soil fertility and structure.
