Star Favourite

Star Favourite dahlias should be planted in a location with full sun exposure and well-draining soil. The planting hole should be around 4-5 inches deep and wide enough to accommodate the dahlia tuber. Place the tuber in the hole, with the "eye" (the pointy part where new growth will emerge) facing upwards.

Cover the tuber with soil, leaving about 1-2 inches of space between the soil surface and the top of the hole. Water the tuber thoroughly after planting and keep the soil evenly moist, but not waterlogged, throughout the growing season. As the plant grows, provide support with stakes or cages to prevent it from falling over in strong winds.

Star Favourite dahlias are typically planted in the spring once the soil has warmed up and all risk of frost has passed. In most regions, this means waiting until after the last frost date, which varies depending on your location.

For example, in USDA hardiness zone 8, where temperatures typically range from 0 to 10°F, the last frost date is typically around April 15th. In zone 6, where temperatures range from -10 to 0°F, the last frost date is typically around May 1st.

Before planting, it's important to prepare the soil by removing any weeds, adding compost or other organic matter, and ensuring good drainage. Dahlias prefer well-draining soil and full sun for optimal growth.

Soaking Star Favourite dahlias before planting is not necessary, but it can be helpful. Soaking the tubers for an hour or two in lukewarm water can help hydrate them, which can encourage faster growth once they are planted.
Soaking can also help to soften the outer layer of the tuber, making it easier for the plant to break through and establish roots.

However, it's important not to soak the tubers for too long, as this can cause them to rot. Overall, while soaking is not required for successful growth, it can be a helpful step for encouraging healthy plants.

No, it is not recommended to leave Star Favourite dahlias in the ground over winter as they are sensitive to frost and cold temperatures. The tubers can easily be damaged by freezing temperatures and can also be at risk of rotting.
It's best to dig up the tubers after the first frost and store them in a cool, dry, and dark place until the next growing season. This will ensure that the tubers remain healthy and will be ready to grow strong and healthy plants next year.

Unless you live in an area with a warmer climate, such as USDA climate zone 8 or higher, then it is possible to leave them in the ground over winter. Make sure to give them an extra layer of mulch in the winter.
