What is WEED KILLERS?

These are essential if there is much in the way of pleasure grounds under the gardeners care. Various proprietary articles are on the market, useful though expensive, and thus some gardeners prefer to make their own. This is easily done as follows : Carbolic Acid.A i% solution of the pure acid (i.e. i part acid to 99 parts of water bulk for bulk) makes quite an effective weed killer, but the pure acid being difficult to obtain in some places the common commercial acid can be substituted and i lb. of this mixed with every 14-15 gallons of cold water. Care must be taken that the acid does not float on the surface but is evenly mixed with the whole, and on no account must any come in contact with the clothes or flesh, as it is very corrosive. The liquid is applied through the fine rose of a watering- can to weedy gravel paths, etc., and a good soaking given. Caustic Soda.A solution of this made by dissolving i lb. in 10 gallons of water is recommended by some as a weed killer, but is still rather in the experimental stage. Its use should be limited to very hot weather on gravel paths, and a good soaking given as before. Copper Sulphate. Copper sulphate, or Blue Stone, has an undoubtedly corrosive effect on green leafage, as is evidenced by scorching if potato-spraying liquids are improperly mixed. This may be turned to advantage as a weed killer in districts where this material is cheap. The use is still in the experimental stage, but a solution of I lb. per 5-10 gallons of water may be used with some success in hot weather. Salt.This is of undoubted vjac as a mild weed killer. It is best applied dry and scattered freely over weedy paths on the first really hot day in the early summer. The weeds will wither in a few hours, and can then be got up without much difficulty. Hot Brine, made by dissolving as much salt as is possible in each gallon of boiling water, is also a splendidly effective weed killer if a thorough soaking of the boiling liquid is applied to young weeds on paths through a finerosed can. Sodium Hydrogen Sulphate. This also is of great value as a weed killer. A strong, almost saturated solution should be made as the material is cheap, and this applied hot through a fine-rosed can. Vitriol.A 4% solution of oil of vitriol (Sulphuric Acid) in water makes a weed killer of enormous valueit is probably the most useful of all. The acid must not be measured in a metal utensil, but in one of pot or well-glazed earthenware to prevent damage. The water should be measured into a wooden tub and the acid poured very slowly into it with constant stirring. If the water-can is used this must be repainted all over before and after use on account of the corrosive action of the acid. This solution may be used at any time, a thorough soaking being given as before. Besides these materials there are one or two mixtures which make good weed killers. Many gardeners swear by a mixture of equal parts quicklime and salt applied in dry weather, but this is objectionable in wet districts. A good solution for watering paths may be made by boiling about i lb. of White Arsenic and the same weight of Caustic Soda together in 4-5 gallons of water until a clear solution results. Then filter and bottle the liquid, using a pint of this stock solution per gallon of water. Warnings on Weed Killers. If any of these liquids remain over after use it should be bottled and labelled”Poisonous”to prevent accidents. These bottles should not be left about, but are best locked up in the tool shed. 1166 The clothes and hands must not come in contact with the majority of the liquids, or bad burns will result. The liquids must be kept away from live edgings, grass verges, dwarf hedges, etc., or the latter will be greatly damaged, if not destroyed.E.
