The Dutch open field vegetable market is experiencing a boost in demand for cauliflower and broccoli due to a seven to ten day gap in supply, resulting in rising prices. The current price for broccoli is between 1.25 and 1.40 euros, while cauliflower is between 75 and 90 cents. The chicory price is around 75-80 cents, with a slight decrease due to increased stem setting. The market is optimistically navigating through the summer, benefiting from increased outdoor vegetable consumption in the Netherlands and losses due to fire in southern Europe.
