Gardening with Carol Klein

The green-fingered expert welcomes viewers back to her garden at Glebe Cottage, in Devon, and discusses her favourite spring flowers - pulmonarias. Carol also introduces a seasonal experiment in intensive veg growing, especially relevant to those with small gardens.

Carol celebrates some of the season's most beautiful - and tiny - flowering treasures, looking at how to choose them, how to plant them and how to care for them. She also visits one of her favourite spring wildflowers in a local wood - the humble celandine - to see how it grows in its natural habitat.

At Glebe Cottage in Devon, the most regal of all the summer bulbs are the regalia lilies, and now is the time to plant them. Many buy them as expensive cut flowers, but Carol reveals how to grow them from bulbs. She also explains the best ways to sow beetroot and brassicas.

Carol is planting onions in her veg garden, and she shows viewers the first shoots of her ornamental allium bulbs, which she planted in pots last autumn. In the greenhouse, there's also a progress report on some of the seeds sown so far this season.

Carol reveals the differences between English and Spanish bluebells, and explains how to rid your garden of this good-looking but thuggish competitor to ensure our lovely native species has a fair chance. The presenter also ensures pond wildlife can get safely in and out of the water.
