Beechgrove Garden is back and celebrating its 45th anniversary.

Across the series, the expert gardeners experiment with growing tomatoes on the windowsill, homegrown salads and vegetables, as well as the traditional Beechgrove Garden potato trials. All summer, the show will have advice and instruction for gardeners of all kinds, from beginner to expert.

There will also be a focus on some particular gardening areas, including a monthly Back to Basics guide, where the team give a masterclass on the key skills needed to be a great gardener.

Kirsty Wilson will be presenting a regular houseplant feature looking at care, selection and some on-trend planting styles for indoor growers, and there is also a focus on gardening for wildlife.

In the first episode, Carole Baxter, George Anderson and Diana Yates assess the state of the garden after a long, cold winter, and launch into the many jobs that need to be done at this time of year, including tips on seed-sowing and planting your own garlic supply. Meanwhile, Calum Clunie sends the first report from his allotment in Leven, and Brian Cunningham provides an update on his garden at Old Scone. There is also a list of top tips to save money in the garden - with household budgets feeling the pinch, how do you plant without spending too much?

It's time to make the vegetable bed at Beechgrove Garden. There are top tips for making your garden as productive as possible, whether you have a border, a balcony, or a window box.

Lizzie Schofield and Calum Clunie guide you through one of the busiest times of the year on the horticultural calendar as the days get longer and the weather warmer. There is another great selection of Handy Hints, and the team tackle the major project of taking down a fence damaged in the high winds of January and coming up with a creative alternative.

If you have moved into a new house and are wondering what to do with that bare garden, there is the start of a new series following the development of a newbuild patch of grass into a great family space. We catch up with father and daughter gardeners Joe and Erin Armstrong in East Lothian, and there is another great garden visit.
