A grid containing 240 wooden planters filled with 23 tonnes of soil collected from gardens across London – from Peckham Rye to Regent’s Park – has been unveiled in the Tate Modern’s Turbine Hall. Entitled Empty Lot, the work by Mexican artist Abraham Cruzvillegas will be lit by lamp-posts made using materials found in skips and building sites around the Tate. The artist has planted nothing in the boxes but flowers, mushrooms or other greenery may grow depending on what seeds may have found their way into the soil. The new installation – the first in the Hyundai Commission series of annual site-specific works by international artists – can be seen in the Turbine Hall on Bankside from today until 3rd April. Admission is free. For more, see www.tate.org.uk. PICTURE: Andrew Dunkley © Tate 2015
