The leaves of waterlilies can be affected by aphids, moth larvae, beetles or midges which can give them a ragged appearance and lead to secondary rots.
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.
The development of brown leaves or dieback of shoots on a much valued specimen can be alarming, but does not necessarily mean you will lose the plant. More often than not, brown leaves, dieback, wilting and leaf drop are caused by weather damage; such as drought, waterlogging, snow, frost or hail.
Weedkillers are designed to kill unwanted plants. Unfortunately, it is all too easy to damage or even kill desirable plants if care is not taken when applying weedkillers. Since there are no remedies, prevention is best.
Contaminated farmyard manure can cause damage to vegetable crops in gardens and allotments. This contamination is caused by application of weedkillers to farmland used to grow hay and other forage which are then eaten by stock.
Paths or patios are sometimes deliberately planted with thymes or other low-growing plants to add interest. However, many unwelcome weeds find their way into drives and the cracks between paving. There are several options to tackling them.
Weeds can be controlled without resorting to weedkillers. Cultural or organic control measures rely on killing or restricting the weeds by physical action, from manual removal to smothering, burning and using weed barriers.
The western conifer seed bug, Leptoglossus occidentalis is a large brown bug native to North America which has become established in the UK since 2007. It feeds on pines but causes no noticeable damage to garden trees.
White blister is a foliar disease that may be found in the garden on a limited range of ornamentals, vegetables and weeds. It can reduce plant vigour, and sometimes also causes distorted growth.
Wild garlic or ramsoms are a pleasing sight in British woodlands, producing a haze of white flowers from April to June. The leaves are edible and add a garlic flavour to salads. However, their persistent bulbs and spreading habit make them a problem in most gardens. The less common but equally persistent crow garlic can also be a nuisance.
We're a UK charity established to share the best in gardening. We want to enrich everyone's life through plants, and make the UK a greener and more beautiful place.
