Growing Info

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 the tubers about 12" apart
When to Plant	Late spring once the soil has warmed up
When to Expect Blooms	Late summer until your first hard frost
Care Instructions	Water regularly once they start to sprout, and then give them regular water. Pick the flowers regularly to encourage more blooms. They are sensitive to frost, so make sure to wait until any threat of frost has passed before planting outside
Extra Credit	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. After your first frost, you can dig up your tubers and store them someplace cool and dark to replant the following spring.
