We love the subtle beauty of October Sky. The 5 inch flowers gently blend from a yellow center to peach, to magenta outer petals. Watch for a variety of colors over the course of the growing season. October Sky has strong stems on a 6 ft plant and blooms in abundance. A real class act, if we do say so ourselves.

How to Plant
Dig a hole about 8-12" deep and mix in compost if you have it. For planting the clump whole, the tuber clump should be fully covered in dirt, but the stem should be sticking out. For planting a single tuber, lay the tuber on its side horizontally 2-4” deep. Cover with soil and gently compress to make your dahlias nice and snug. Mark the spot with support (a stake or tomato trellis works well) for the big blooms to come. Tubers are prone to rot, so only water if the soil is very dry, otherwise leave it be until it starts to grow.
Where to Plant
Find a place that gets mostly sun, and space plants about 12" apart.
When to Plant
Plant outside after your average last frost in the spring, when the ground has warmed.
When to Expect Blooms
Mid-summer through frost.
Water regularly once they start to sprout, and then give them extra water during dry spells. Pick the flowers using a sharp tool (Bring the flowers in! Make bouquets! Have fun!) to encourage more blooms. They are sensitive to frost, so make sure to wait until any threat of frost has passed before planting outside. And ask us any questions along the way.
When the plant is about 12" tall you can pinch it back, (which is to clip off the first main middle bud), so that the plant is encouraged to be bushier and more full of blooms as it matures. In places with mild climates, generally zones 7-10, Dahlias are tender perennials, but in places with freezing winters they are annuals. After your first frost, you can dig up your tubers and store them someplace cool and dark to replant the following spring.
