    Frequently Asked Questions

    In terms of height, they typically grow to be about 3 to 4 feet tall. However, the actual height can vary depending on growing conditions, such as soil quality, sunlight exposure, and temperature. Kelvin Floodlight dahlias are known for their large, vibrant yellow blooms that can reach up to 10 inches in diameter.

    To ensure optimal growth and height, it's important to plant Kelvin Floodlight dahlias in well-draining soil with plenty of sunlight. They also benefit from regular watering and fertilization throughout the growing season. With proper care, these dahlias can reach their full height potential and produce stunning blooms that brighten up any garden or landscape.

    Kelvin Floodlight dahlias typically take around 2-3 weeks to sprout after planting the tubers. It is important to know that you need to plant them in the proper planting season. In colder climates, this is between late spring and early summer, as soon as the threat of frost has passed.

    The exact time may vary depending on factors such as temperature, soil moisture, and the condition of the tubers. Dahlias prefer well-draining soil with plenty of organic matter, and they grow best in full sun.

    Before planting the tubers, it's a good idea to soak them in water for a few hours to help rehydrate them. Once planted, keep the soil moist but not waterlogged, and be patient. With proper care, your Kelvin Floodlight dahlias should begin to grow within a few weeks.

    Kelvin Floodlight dahlias are typically planted in the spring after the last frost has passed and the soil has warmed up. This usually means planting them in mid to late May in most parts of the Northern Hemisphere.

    Dahlias are susceptible to frost damage, so if there is a risk of frost after planting, cover the area with a frost cloth or straw mulch until the danger has passed. With proper care and attention, Kelvin Floodlight dahlias will produce beautiful, large blooms in late summer and early fall.

    In an area with a warmer climate, such as USDA zone 8 or higher, is it possible to plant them earlier or even leave them year-round in the ground.

    Follow the following steps to plant Kelvin Floodlight:

    • Choose a location with full sun and well-draining soil. Dahlia plants prefer a soil pH between 6.0 and 7.5.
    • Dig a hole that is twice the width of the dahlia tuber and about 4-5 inches deep.
    • Mix some compost or well-rotted manure into the soil at the bottom of the hole.
    • Place the dahlia tuber in the hole with the "eye" facing up and cover it with soil. The "eye" is a small bump on the tuber where the stem will grow.
    • Water the plant thoroughly and keep the soil moist but not waterlogged.
    • As the plant grows, provide support with stakes or a cage to prevent the stems from falling over.
    • Fertilize the plant every few weeks with a balanced fertilizer.
    • Remove any dead or damaged leaves or flowers as they appear.
