How to grow alliums

These ornamental onions are bold and architectural, with large rounded heads of usually purple flowers, followed by attractive seedheads. Weave them through sunny borders or combine them with feathery grasses for best effect.

Flower size and colour Alliums are available in shades of blue, purple, mauve, pink, yellow and white and with a range of flower head sizes from just a few centimetres to 18-20cm (7-8in) in diameter Height Tall alliums such as Allium stipitatum ‘Mount Everest’, which can be over 90cm (3ft) in height, add an architectural quality to your garden. You can plant them in the middle of a border where they can stand above shorter neighbours. You can plant smaller-flowered alliums, for example Allium cristophii, in clumps nearer the front of the border or in the rock garden.

Dig over the soil and remove any weeds before planting. Avoid planting into freshly manured soils which may be too nutrient rich. Plant bulbs in early autumn at a depth of about four times the diameter of the bulbs. Plant smaller growing alliums 7.5-10cm (3-4in) apart, and taller species need at least 20cm (8in) between the bulbs. Regular feeding is not necessary but on poor soils, apply balanced fertiliser such as Growmore in spring.

Rose pruning: climbing roses

Rose pruning ensures that plants grow vigorously and flower well each year. If left, climbing roses can become a tangled mess of branches with very few flowers. Although often considered complicated, rose pruning is not difficult if you follow this guide. Such plants fall into RHS Pruning group 17.

This method is suitable for climbing roses. Sometimes it can be hard to distinguish between a climbing rose and a rambling rose. The easiest way to tell the difference is to take note of the flowering time. A climbing rose will repeat-flower almost all summer and well into autumn, while a rambling rose usually flowers only once, normally around June.

Climbers are routinely pruned in winter, after the flowers have faded, between December and February. Long whippy shoots can be shortened or tied in during autumn, to prevent strong winds from damaging them. Renovation can be carried out at any time between late autumn and late winter. It is easier to see what you are doing when the rose is not in leaf, plus there is a better response from the rose, which should grow back vigorously the following spring.
