  • Phalaenopsis 'Kung's Green Star' displayed by McBeans Orchids. Hampton Court Palace Flower Show 2007. Tim Sandall/RHS The Garden

    Phalaenopsis (moth orchid)

    Phalaenopsis (moth orchids) grow well in centrally heated rooms and have long-lasting flowers produced all year round. They are one of the most popular indoor orchids.

  • A pleached hedge at RHS Garden Wisley

    Pleached walks, tunnels and arbours

    Pleaching is a method of training trees to produce a narrow screen or hedge by tying in and interlacing flexible young shoots along a supporting framework. Use this technique to make walks, arbours, tunnels and arches.

  • Poinsettia

    Poinsettia

    Poinsettias are cheery plants that are widely grown indoors over Christmas for their brightly coloured bracts. They are often disposed of once they start to fade, but with a little care, you can keep them all year and the bracts will colour up again the following year.

  • blanket weed

    Pond algae and blanket weed

    Algae can be a major problem in ponds, causing discoloured water, green scum at the pond edges, or dense mats of green growth under the surface. If conditions are favourable, algae will spread quickly and can harm aquatic life.

    Pond care

    Ponds are a lovely addition to any garden and can provide a rich habitat for a range of wildlife. However, without care ponds can soon become an eyesore with overgrown plants, weeds and water that is unhealthy for fish and other wildlife. Occasional cleaning and regular maintenance are required.

    Pond construction and repair

    There are a number of ways of creating a pond. Most involve excavating a hole of the required shape: what is different is the type of impervious material used to line the hole. These include flexible waterproof liners, semi-solid preformed ponds and concrete.

  • Pond filters

    Pond filters

    Pond filters are used to maintain a healthy pond by keeping it clear of algae and some of the debris which, in turn, helps to keep fish healthy.

    Raised beds

    Raised beds are a great way of growing a wide range of plants, and are particularly popular for growing fruit and vegetables. They are a good way of boosting drainage and can be used to introduce a different soil type to your garden. Raised beds are also a useful way to garden if you have restricted mobility, as they reduce the need to bend.

    Red thread

    Red thread is one of the most common fungal patch diseases found on lawns, particularly where the turf is deficient in nitrogen. It causes brown patches of turf, especially during a wet summer.

  • Roof gardens and balconies

    Roof gardens and balconies

    If you live in a building without its own garden, establishing a roof or balcony garden is the ideal way to create your own mini horticultural haven, ensuring you don’t miss out on growing a wide range of plants.
