With more demand for space to build, gardens are getting smaller. In fact, owning a garden is just a dream for many younger people. This week, David Maxwell and the team will explore the options for those with no piece of earth to call their own. How can those with more than they need (or more than they can look after) make land available to those without. David chats to a Belfast born entrepreneur who’s developed an online platform where garden space can be rented out to those who want to grow their own food but don’t have a garden. Also on the programme, RHS Wisley curator, Matthew Pottage on making the most of the garden if you are renting your home and for those who have to garden indoors, some must have houseplants from Danae Diaz.
