Fiann's tips for the week

* Asparagus crowns can go in now and any perennial veg can be divided.

* Now is the time to dig up chicory roots to be forced in a dark warm place. The chicons will be ready to harvest in three to six weeks.

* Protect cauliflower curds by folding their leaves over as natural wrapping. This delays the opening of the flowers better than fleece and keep the curds nicely compact.
