I have grown some healthy looking and large brussel sprouts plants. However
the sprouts themselves need a lot of preparation as they have what seems
like dirt inside, indeed some are so badly infected as to be useless. When
cleaned and cooked they are delicious, however it would be nice to be able
to prepare them easily. Especially on Boxing Day when there are 16 for
dinner!

Apart from cabbage butterfly caterpillars they seemed free from problems.
Any ideas of what it might be, and the prevention for next year?

Caterpillar droppings?
