I've found them very easy to grow over the years. Here's a bit of info .
Dahlias will grow in almost any location and in almost any soil.
However, to have outstanding plants and flowers, you must be selective of the planting placement.
Dahlia roots need a sunny location in order to thrive. They should receive at least a half-day of sun and even more is preferable.
Select a site for your dahlia garden that is away from trees, sunny, and yet sheltered from direct wind.
Dahlia tubers are surface feeders.
Since they don’t send down a tap root or long feeder roots the plants will easily be blown over by the wind.
Staking the plants is essential and will be covered later with planting instructions.
A further important consideration is the condition of the soil.
In most cases, a good everyday garden soil is adequate.
But good soil drainage is vital for dahlia plants.
If the soil holds surface water for more than several hours after a rain, the likelihood is that it should be augmented with organic matter.
Humus, peat moss, sand, or well-rotted manure will work well. A mixture of equal parts of all of the above makes an excellent addition to heavy soil.

Agree with kiwi except I just let mine grow wild Never bothered with the stakes. They are really tough but when you take them up after the first frost they say to knock off the dirt but I never do I just put them in baskets and store in the root cellar,and forget them till spring,

they certainly are easy to grow, with the strong winds that we get here, we either have to plant them in a sheltered spot or stake them.
