What you are experiencing sounds a lot like
Phytophtera Blight. This organism attacks the plant at the soil line. It infects
the plant in a ring around the stem. The tissue becomes dark and soft. The plant
is effectively girdled and dies. Rotation is an important part of keeping this
disease under control. If your compost was not completely degraded, pathogens
could survive in it. If you used tomato, pepper or potato plant material in it,
the pathogens could have come from there, even if the plants that you composted
didn't look diseased. This is one of the reasons the compost process needs to be
nurtured carefully and thoroughly before the compost is used.
Some interesting comments came through the
forum. Some of the teas might be helpful for those plants not yet infected. The
idea of using a "handful of fertilizer" at the base of the plants is probably
not good, even if organic. Often, a handful of fertilizer is to a plant what a
bottle of vodka is to you and me, especially if the fertilizer has a high
analysis. It's better to just make sure the soil has appropriate fertility
before planting. Use a liquid starter fertilizer to give the transplants the
proper boost. The liquid disperses into the soil where dry fertilizer remains
concentrated around the base of the plant.
Also, the problem of the plant being
rubbed by the plastic and damaged is a real one. Making larger holes and
planting properly helps, as does covering the edges of the hole with soil (HINT:
Use this technique with clear plastic mulch and the weeds won't grow underneath
the mulch. Try this on melons and you'll see them come in earlier than on other
mulches).
