Know before you buy
These plants reach a mature height of approximately 4 feet. Because of their size and the weight of the 10-12 inch blooms, you should plan to provide staking or support for the stems.
Kelvin Floodlight dahlias require full sun, which means at least 6 to 8 hours of direct sunlight daily. Planting them in a spot with adequate light ensures the best bloom production and stem strength.
Space your tubers 18 to 24 inches apart. This provides enough airflow to prevent fungal issues and gives the plants sufficient room to develop their large, decorative blooms.
You can expect the first blooms to appear in approximately 80 to 100 days after planting. This timeline can vary slightly depending on your local climate and soil temperatures.
Yes, they are excellent for cutting gardens. Their formal decorative structure and impressive 10-12 inch size make them a standout choice for large floral arrangements.
