Rembrandt

The secret to growing Rembrandt dahlias is to provide them with the right growing conditions. These flowers thrive in full sun, so it's important to plant them in an area that receives at least 6 hours of direct sunlight per day.

They also prefer well-drained soil that's rich in organic matter, so adding compost or other organic materials to the soil before planting is beneficial. It's important to keep the soil consistently moist but not waterlogged, and to avoid overhead watering as it can promote the growth of fungal diseases.

Regular deadheading of spent blooms will encourage continued flowering throughout the growing season.

Rembrandt dahlias are a dahlia variety that produces large, colorful blooms with irregular patterns. In general, dahlias are not winter hardy and should be lifted and stored over winter in areas where temperatures drop below freezing.

However, Rembrandt dahlias may be hardy in some milder climates or sheltered areas. If you live in a region with mild winters, such as USDA hardiness zones 8 or higher, you may be able to leave Rembrandt dahlias in the ground with some winter protection.
However, it is generally recommended to lift and store them to ensure their survival and optimal growth the following year.

Yes, Rembrandt dahlias can come back every year if they are properly cared for and provided with the right growing conditions. Dahlias are not hardy in colder regions, so they need to be dug up when the first signs of frost are coming. Lift them up carefully and store them in a cool and dry place.

In warmer climates, such as USDA climate zones 8 or higher, it is possible to leave them in the ground. Give the dahlias an extra layer of mulch and they’ll come back for several years.

To ensure that Rembrandt dahlias return year after year, it is important to plant them in well-draining soil and in a location that receives full sun. Regular watering, fertilizing, and deadheading of spent blooms can also help promote healthy growth and increase the likelihood of the plant returning each year.

Soaking Rembrandt dahlia tubers before planting can provide some benefits, but it is not necessary. Soaking the tubers in water for a few hours before planting can help rehydrate them and encourage sprouting.

Additionally, soaking them in a solution of fungicide can reduce the risk of fungal infections. However, soaking the tubers for too long or in too much water can cause them to rot, so it's essential to be cautious with soaking times. Ultimately, whether or not to soak the tubers is up to the gardener's specific needs of their planting location.
