In Gardeners World episode 16 2017:
Agapanthus (African lily) are summer-flowering perennial plants, grown for their showy flowers, commonly in shades of blue and purple, but also white and pink. They thrive in any well-drained, sunny position in the garden, or grow these beauties in containers.
Green manures are fast-growing plants sown to cover bare soil. Often used in the vegetable garden, their foliage smothers weeds and their roots prevent soil erosion. When dug into the ground while still green, they return valuable nutrients to the soil and improve soil structure.
Semi-ripe cuttings are an easy way to propagate a wide range of hardy climbers, herbs, ground-cover plants, shrubs and trees – especially evergreens – without the need of special equipment or skills.
Air layering of plants
Air layering is a method of propagating new trees and shrubs from stems still attached to the parent plant. The stem is wrapped with damp moss to encourage roots to form.
Wisteria needs regular pruning to keep the growth and size under control, but it will also improve the flowering display. Although it seems complicated, wisteria pruning is quite simple if you follow our simple guide.
