Dahlia Care Guide

  • Pre-Season Storage

    Your tubers will arrive bagged with wood shavings. Store your tubers in a dark and cool 40-50 degrees(F) place until you are prepared to plant.

  • Planting

    It is safe to plant your tubers in your garden after your last frost dates when the soil has reached 60 degrees(F) (or when you would plant your tomatoes). Plant your tubers with the eye facing upwards (horizontal) 4”-6” deep and 12”-24” apart.
    Don’t plant dahlias in soil that does not drain well or has not dried out yet from wet spring weather. Dahlia tubers are most likely to rot between when you plant them and when the sprouts burst forth from the ground, so do not water at this time unless the soil becomes bone dry!
    Begin to water after you see sprouts pop through the soil. Once the plant reaches 12” begin to increase the watering as mature dahlias are true water hogs.

  • Protecting/ Supporting

    Most varieties grow tall and will need support so we suggest putting a stake next to your tuber when you plant them initially to not disturb the roots later and it will be there to support your beautiful blooms!
    SLUGS love dahlias so be on the lookout for slime trails and evidence of critters in the garden.

  • Bloom Production

    To encourage more blooms on
    your plant you'll want to "pinch" the tops. When it gets to 12 inches tall, with 3-4 sets of leaves, simply remove the growing tip of the stalk above the top set of leaves. This will force the plant to branch out, ultimately providing more blooms for you!
    When blooms begin to appear in late summer remember to cut deeply and deadhead to allow the production of even more blooms.

  • After Season Care

    Your tubers will produce blooms from late summer until frost. After that the plants will die back to the ground. Wait a week then dig up your tubers! Your original tuber will have become a clump of tubers. You can choose to split them at this point or to store them as a clump. If you are new to growing dahlias there are many great resources online that can show you how to split tubers.

    Store your tubers in a cool dark location (40-50 degrees (F)). We recommend you look up the best storage medium and location for where you live.
