A few tips for successfully growing your dahlia tubers:

  1. Plant them when the soil is not soggy and about 60 degrees.  Dig a hole 4-6” deep, lay the tuber on its side, add a bit of bone meal, and put a stake so you won’t stab the tuber by accident later. Cover it with soil, and don’t water until you see the sprout.

  2. They love as much sun as you can give them, hopefully at least six hours a day.

  3. They want weekly summer water to encourage sustained bloom.

  4. The more you cut off the fading flowers, the more flowers will follow, all the way to first heavy frost. So do cut the flowers to enjoy in the house and to share with friends.

  5. Once they are up and growing, They like occasional supplemental feeding with a seaweed or other liquid fertilizer, mixed no stronger than recommended.  Tomato fertilizer is good for them too.

  6. The taller varieties benefit from staking, especially in windy areas. Tomato cages can be helpful for a large plant.

  7. Slugs love emerging dahlia shoots. Be sure to use preventative measures (slug bait, diatomaceous earth, or other strategies), even before you see the green sprout.

Concerned about what to do when the frost hits? You have choices!

  1. If your soil is very soggy in winter, your dahlia tubers will do best to be lifted and the stems cut back.  The whole plant can be potted up and stored in a frost-free space. Or you can wash off the soil, let the tubers dry a bit, dust them with sulfur, put them in boxes with sawdust or vermiculite, and then store the boxes in that frost-free space. 

  2. In most of our winters, if your soil has decent drainage, you can leave them in the ground. A little preparation will encourage success. The main objective is to keep water from going into the hollow cut stems. Some people cover the dahlia bed with black plastic and then mulch over it.  If your dahlias are scattered through the garden, a black nursery pot filled with leaves provides snug protection from the rain and freezing.

  3. Or treat them as annuals and just be grateful if they survive, as they often do. At our low prices, they are no more expensive than bedding annuals.
