We offer expert advice on a wide range of garden features; see our A - Z directory.
Create a miniature alpine landscape with year-round interest. Planting into sinks and troughs raised off ground level lets you admire these often brightly coloured jewels close at hand.
Slime moulds occasionally cause concern when they appear on lawns, but they do not attack or kill the grass. They vary greatly in their colour, size and form. Their spore-producing structures are often very fragile, disintegrating when touched.
Strelitzia reginae is commonly known as the bird of paradise flower. This south African native has glaucous banana-like leaves and bright architectural flowers. It makes a striking addition to your conservatory.
Streptocarpus are popular, relatively inexpensive, moderately easy-to-grow houseplants in a wide range of attractive colours which will produce flowers over several months. They are also easy-to-propagate.
Take-all is a fungal disease of lawns, particularly those with a high percentage of fine bentgrasses (Agrostis spp.). It causes brown patches of grass, most often in summer when the turf is under drought stress.
Wild flowers have never been more popular with gardeners. But what is meant by 'wild flower' on a packet of seed to one person may not be the same to another. To help minimise confusion, the RHS has prepared the following guidance based on consultation with the horticultural trade and organisations.
This page does not an attempt to define ‘wild flower’ in the broader botanical or conservation sense but for garden use only.
Viburnum beetle can cause severe defoliation of some Viburnum species, especially V. tinus and V. opulus.
For gardeners with a warm, heated conservatory or greenhouse there are lots of interesting plants to choose from.
Lawns can become waterlogged if water sits on the surface and drains slowly. Waterlogging is more likely to be a problem on compacted and clay soils. However, it is worth noting that patches of dead grass where the soil proves very difficult to re-wet can be caused by a fungal problem: dry patch.
Wildflower meadows are an alternative to lawns and borders, and can provide a display for many months. Choose from annual meadows that provide a one-off show or perennial meadows that persist from year to year.
