I understand that fusarium is supposed to die out if no suitable host plants
are available. I have waited years between tries, and the asters die next
try. I have tried several varieties of aster, with the same result. I have
tried different end of the garden. No luck. There are no plants nearby
that I recognize as disease vectors. Asters in pots do fine until I put
them in the ground. Asters in the city parks grow fine, and the city does
not use any preventative chemicals.

How can I grow asters in my garden?

In large decorative pots, as accents. For many years to come.

I assume you are having trouble with the annual (China) asters, correct?
"Dwarf Queen" and "Gem" series are described on one site:

as being fusarium resistant, but that might only lead to more heartbreak...
