We have used the vitax clay breaker with moderate success on the areas
of the garden where there is just 'clay', but we haven't even tried to
use it on the areas where there is the sticky grey/blue clay stuff.
We also dig in about the same volume of compost and sharp sand to clay
and keep adding more compost every year. We have been here 11 years and
the first beds we tackled are just beginning to look like proper soil

When the Dutch moved much of the bulb growing from the Bollenstreek,
Zuid Holland to West Friesland 80km. north, they used large
quantities of sand pumped from the IJsselmeer to break down the clay.
It seems to have worked.
