At Longmeadow, Monty is planning for next summer by sowing a batch of sweet peas. He wants to find out, by sowing a batch now and another next spring, whether the flowering and general performance of the plants will differ. Carol Klein is amongst the leaves, bark and berries at Thorp Perrow Arboretum in Yorkshire admiring the onset of the autumn display, and recommends varieties suitable to plant in our gardens. Plus, a visit to Ryton Gardens in Warwickshire to find out about their collection of heritage vegetables and how to collect their seeds, and back at Longmeadow, Monty plants daffodils and anemones in the dry shade under trees for a spring display.
