With the nation needing its gardens more than ever during lockdown and growing our own food becoming a collective obsession, Alan Titchmarsh shows us how he does it.

Frances Tophill adds flowers with pest-fighting power to her tiny veg plot, and Katie shows us how to construct a vertical garden that will suit any budget.

Alan harvests the first of the radishes he planted as seeds, and steps into his greenhouse to grow an exotic treat. Frances Tophill gives a seed-to-plate guide to growing your own chillies, David grows barbecue favourites, and Katie gets healthy.

Alan Titchmarsh creates a cutting garden in the veg plot, with flowers to pick for the home from summer till the first frost. Frances Tophill moves ever closer to finishing the stunning make-over of her tiny plot in Folkestone, by sharing the secrets of growing free plants from scraps from the veg drawer. Elsewhere, in her converted barn in Yorkshire, Katie Rushworth stays indoors to grow soil-free herbs in a beginners' guide to hydroponics.

The team reveal their individual garden make-overs, and the results are beautiful. Alan, filmed by his wife Alison, adds a beautiful final border of bee-attracting flowers to keep his veg patch pollinated and beautify the whole area. Frances' garden transformation is revealed, from tiny bare backyard to cosy kitchen-garden sanctuary. She completes it with a final addition of veg-filled hanging baskets.
