Islander

To plant Islander dahlias in the ground, first, select a sunny location with well-draining soil. Dig a hole that is about 4-5 inches deep, and amend the soil with compost or organic matter. Place the tuber in the hole with the eye facing up and cover it with soil, but do not bury it!

Water thoroughly, and continue to keep the soil moist but not waterlogged throughout the growing season. When the plant reaches 12 inches tall, pinch off the top two sets of leaves to encourage branching. Stake the plant and remove spent blooms to encourage continuous blooming. Dahlias typically bloom from mid-summer to the first frost and can be dug up and stored over winter in colder climates.

Soaking Islander dahlia tubers before planting is not necessary, but it can help jumpstart the growing process. Soaking the tubers in lukewarm water for a few hours can soften the hard outer layer, making it easier for the plant to sprout.

However, it's essential not to over-soak the tubers as they can become waterlogged and susceptible to rotting. If you decide to soak your Islander dahlia tubers, it's best to do so for no more than 2 hours. Additionally, it's important to plant the tubers in well-draining soil and keep the soil moist but not waterlogged to ensure optimal growth.

Islander dahlias are a type of dahlia that is hardy in USDA zones 8 or higher. In these zones, it is possible to leave Islander dahlias in the ground over winter, as long as they are protected from freezing temperatures. This will help to insulate the roots and protect them from the cold.

In colder zones, the Islander dahlia is absolutely not hardy and it is best to dig up the tubers in the fall with the first sign of frost. Lift them carefully up, clean them, and store them in a cool, dry place until the next growing season.

Islander dahlias should be planted approximately 4 to 5 inches deep. Planting the tubers too shallow can result in weak, spindly plants and a lower yield of flowers. On the other hand, planting them too deep can delay growth and cause the tubers to rot.

To plant Islander dahlias, dig a hole that is slightly wider than the diameter of the tuber and add a small amount of compost or fertilizer to the bottom of the hole. Place the tuber in the hole with the stem pointing up and cover it with soil. Don’t bury it! Water the newly planted dahlia thoroughly and continue to water regularly to ensure healthy growth.
