Caring for Your Dahlias & Cannas

Before Planting

  • Slowly introduce plants to the outdoors over a few days before planting.

  • Keep them near a wall or protected area at first to reduce wind stress.

  • Avoid leaving them outside overnight if temperatures are below 50°F.

  • Many people wait until after Memorial Day to plant outdoors, but if your plant is getting large for its pot, drying out very quickly, or becoming top-heavy/rootbound, it’s probably ready to plant outside soon.

  • Dahlias and cannas can be planted either in the ground or in large pots/containers.

Planting Tips

  • Water after planting.

  • Liquid seaweed fertilizer can help reduce transplant stress and encourage healthy growth.

  • For dahlias, place a stake at planting time. As blooms get heavier, stems can flop or snap, so tie plants gently as needed using Velcro plant tape, cloth strips, or other soft ties.

Rabbit Protection

  • Young plants are especially tasty to rabbits.

  • For the first ~6 weeks after planting, temporary fencing can help protect plants while they harden off.

Cutting Flowers

Dahlias

  • Cut blooms early in the morning or in the evening.

  • Choose flowers that are fully open, since dahlias do not continue opening after cutting.

  • Cut stems deep into the plant to encourage more blooms.

Cannas

  • Remove spent flower stalks once most blooms on the stalk are finished.

End of Season / Winter

  • After the first frost blackens the foliage, cut stems back and dig up tubers/rhizomes if you want to save them for next year.

  • Store somewhere cool, dark, and dry over winter.
