WEEDS AND WEEDKILLERS

Satisfactory destruction of weeds depends on correctly timing the application, particularly with liquid weedkillers.

Best results are obtained by applying liquid weedkillers on a dry day, though the surface must be sufficiently moist for the plants to take up the solution. If the paths are dry and hard, soak well with water before application. Withhold treatment if heavy rain is expected. Apply weedkiller solutions with a watering can fitted with a fine rose. One thorough application, if made in the spring before weeds have had time to become firmly established, is usually sufficient, but further treatments may be needed on badly infested areas. Protect grass verges and flower borders by a piece of board which can be moved along the path borders as application proceeds.

Sodium chlorate can be applied in dry form or mixed with water to facilitate distribution. It destroys practically all plant life except mosses but under certain conditions is highly inflammable. If clothing, straw or dead vegetation becomes soaked with the solution and then dries a spark or even friction will cause an explosion. If any clothing becomes wetted with this weedkiller, rinse carefully with plenty of water. However, in a relatively damp climate such as that of Britain, the risk is not great and in any case sodium chlorate can be obtained mixed with a fire depressant which reduces any fire risk to the absolute minimum. Note that sowing or planting cannot be undertaken for at least 6 months after sodium chlorate applications. On heavy land with a low rainfall, persistance is greater than on very light ground which receives planty of rain.

Phenol type weedkillers are less persistent than sodium chlorate and tend to burn off the tops of the weeds, without necessarily getting down to the roots. They are, however, highly effective against moss on paths. See SELECTIVE WEEDKILLERS and LAWN MAKING for details of selective weedkillers such as MCPA, 2, 4-D and 2, 4, 5-T. When applying weedkillers on paths, lawns or elsewhere apply the full amount over the whole area, as bare patches of ground contain hosts of weed seeds which will germinate freely unless treated with a weedkiller.

WEIGELA, DIERVILLA or BUSH HONEYSUCKLE FLOWERING SHRUB. These are atractive shrubs flowering in May and June on the previous year’s shoots, sometimes giving a smaller second flush of bloom in late summer. They grow to about 6 ft. The tubular flowers are usually pink or red. Easily increased by cuttings in spring. Abel Carnere is reddish-pink, Conquete pale pink with extra large flowers and Newport Red rich red.
