Garden Hardiness

Remember all ferns need some form of winter protection. Deciduous species that fade in winter and shoot up again in spring, should be protected by folding the fronds over the crown in winter and put an upside down plant pot on top, weighted down with a rock. This will also stop the crown being stood on in spring. A pile of hay can also be used to protect crowns, and mark positions. Potted plants, should be moved to a sheltered spot in winter away from winds which will dry them out too much.
