Brassica blindness

Question ...

For a number of years now, I have sown brassicas in modules and plant them out in well-prepared soil. This year they all grew well (under a net to guard against pigeons). There was not a single head on any plant what has gone wrong?

Answer ...

Blindness arises when growth stops through the absence or malfunction of the growing point. There are various causes of blindness, damage from a pest or disease attack, nutrient deficiency, water-logging or dryness are also common causes.

Next season ensure that crops are watered well in periods of drought, maintain good drainage if plants are getting waterlogged. Maintain a regular feeding regime so that plants are less susceptible to pest and disease damage.
