Learn about pruning with expert advice from the RHS
Pruning late-summer and autumn flowering shrubs in spring will keep their growth in check and improve flowering.
The rod and spur pruning system is usually used for indoor grapes in greenhouses or conservatories, and for growing grapes against walls outdoors. It is also called the cordon system.
Perennials and shrubs that form an attractive carpet can be put to good use in the garden, especially when looking for low-maintenance options.
Hamamelis is a winter-flowering shrub, commonly known as witch hazel. Its spicy fragrance and spidery flowers in yellow, orange and reds make it a must for the winter garden.
A selection of heathers in your garden can offer bee-enticing blooms for all seasons of the year. They create evergreen ground cover, and offer great variation in foliage and flower colour and some are scented. For cold sites, containers and late season interest, they are hard to beat.
Tall hedges can be a nuisance, especially where neighbours can’t agree on a suitable height amicably. However, legislation now gives people whose gardens are overshadowed the opportunity to resolve the problem with the help of the local council.
Hedges require formative pruning on planting, plus maintenance trimming to keep them within bounds. Pruning times vary depending on the type of hedge.
Hedges can quickly become overgrown, filling up a border and becoming difficult to maintain. Renovation may rejuvenate an old hedge. With legislation in place concerning the height of evergreen hedges, renovation may be advisable where hedges have got out of hand.
Established hedges require trimming to keep them dense and compact. Formal hedges require more frequent trimming than informal hedges.
Hellebores (sometimes known as the Christmas or Lenten rose) are perennial garden plants with elegant flowers, perfect for brightening up shady areas during late winter and early spring. Some species are grown for their striking evergreen architectural foliage.
Hemerocallis (daylilies) produce elegant, usually trumpet-like blooms in summer and are easy to grow in many gardens. Individual flowers are short-lived but each plant produces many flowers, so displays will last for weeks.
