Q What can we grow against a trellis set around our oil tank to disguise it?
A Growing climbers in pots is a suitable way to cover your trellis but the main problem here is that the plants will require regular watering, all year round. Three plants should do it. Select containers that are at least 30cm (12in) deep and ideally more than 45cm (18in) wide and use John Innes compost. Good evergreen climbers include ivies, honeysuckle and, on a south-facing trellis, trachelospermum (below).
