Seasonal Tip
Protect the soil. Heavy winter rain in Ireland can wash all the good nutrients out of bare garden beds. Cover empty vegetable patches with a thick layer of well-rotted manure, compost, or even a deep blanket of fallen autumn leaves. The worms will slowly pull it into the soil for you, leaving it perfectly ready for spring.

Did you know?
Parsnips and Brussels sprouts actually taste much sweeter after a hard winter frost has hit them. When the temperature drops near freezing, the plants get tricky: they convert their stored starches into natural sugars to act like an internal ‘antifreeze’ so their cells don’t burst.
