They're easy for me so I don't know what might be causing your
Summers should be hot enough in Vista and your winters aren't
that cold.
Maybe put your plants in the ground where they won't get too wet
in the
winter? Or try them in a bigger container.

They don't produce much top growth the first 2-3 years but are
making a
big tuber. I had one produce a tiny thread stem and only 4 small
the first year, but the tuber was bigger than most sweet
potatoes sold in

They don't emerge from dormancy until it's good and hot, so you
might want
to wait a while to start watering, or put the pots someplace hot
as soon
as you can. I wouldn't water them during cold weather. And I
would make
sure the pots don't freeze in the winter. I lost a big plant in
the ground
years ago during a heavy freeze here in Phoenix.

Another option would be to put them someplace warm and sunny and
keep them
growing through the winter, if such be available. They are
evergreen and
ever-blooming in Baja California.
