Growing tips

Celeriac prefer a soil that is kept moist at all times so be sure to keep well watered during hot and dry periods.
To promote further root growth remove any side shoots when they appear on the plant.
Avoid feeding with any fertilisers that are high in nitrogen as this will reduce the growth of the root ball.
Smaller bulbs tend to have a sweeter taste making them perfect for adding to salads and purees.
Celeriac can be used in a wide range of dishes such as salads, or used in soups, stews, and purees or added to mashed potato.
