Karma Sangria dahlias are a popular variety of dahlia known for their vibrant red and pink blooms. While dahlias are technically perennials, meaning they have the potential to come back year after year, whether or not Karma Sangria dahlias will return annually depends on several factors.
Firstly, dahlias are sensitive to frost and require warm, well-draining soil to survive the winter. If the soil is too wet or the temperatures are too low, the tubers may rot or freeze, preventing the plant from returning the following year. Additionally, in colder climates, you need to dig Karma Sangria dahlias up and store their tubers over the winter to ensure their survival.
If you live in a warmer climate, then you can just leave them in the ground and they’ll come back every year. Just don’t forget to cut spent blooms off.
