What to do in the garden in March

At last spring is on the way. Usually we enjoy warmer days come mid-March, and the longer, sunnier days provide the opportunity for an increasing range of gardening tasks. It’s time to prep seed beds, sow seed, cut back winter shrubs and generally tidying up around the garden.
