FIGHT THE WEEDS
The chiefwhich grow in a lawn are daisies, dandelions, buttercups, white clover, yarrow, plantains and moss, and as most of these ripen and shed their seeds by the end of June, it is obvious that they are best treated before that time.
With the surface-rooting ones, such as buttercup and yarrow, ann the short-rooted rosette plants like the plantains, the best plan is to pull them out by hand, using when necessary a smallfork. For dandelions, a flat-pronged digging fork may be needed, their roots run so deep. If not carefully pulled out, a small piece of dandelion root will grow again into another plant.
When you weed, work systematically over the lawn, section by section until every weed has gone.
Have at hand some grass seed mixed with fine sand, and as the weeds are removed, fill up the holes with this mixture. Press thedown hard, and afterwards roll, but do not water the lawn.
Weeds are only “plants in the wrong place” as a poppy is among the corn. Their growth is a natural occurrence, and every gardener has to wage an endless war against them. One thorough weeding will not finish the matter; on the contrary, unless the weeds are kept under control they will finish the lawn.
The use of weed-killers will, however, reduce labour to some extent, and the weed-killer most commonly used is lawn sand. This is broadcast over the lawn at the rate of 2 oz. per square yard. Any bright day in the year will serve for this broadcast. Lawn sand can be made by mixing lb. of sand with 3 lb. of sulphate of ammonia and 1 lb. Sulphate of iron, or it may be bought in small bags, ready mixed.
Lawn sand burns the grass and for a week or so it will blacken weeds and grass alike, yet, after that time, the grass will revive and be all the better. Any further weeds that make their appearance may be spot-treated.
This consists in putting a small spoonful of lawn sand in the centre of each weed. Plantains can be killed by cutting off the tops and putting a pinch of lawn sand on to the stumps.
Weeds with long tap roots, such as dandelions, can be quickly destroyed by squirting a little liquid weed-killer into the centre of the crown of the plant. Prepare the weed-killer at double strength, then treat each plant and in a few days they will all be dead. Special tools, which, when pressed into the heart of the weed inject a spot of weed-killer, are sold by all sundriesmen. Other weeds can be treated in this way too, but the application of lawn sand is usually enough for weeds without tap roots.
A lawn which is unusually weedy should be dressed with ½ oz. of sulphate of ammonia to the square yard once a fortnight all the summer. In order to allow for even distribution, mix the sulphate with ash or fine sand, and dust carefully over the lawn, section by section.
Newly-sownshould always be weeded by hand. In showery weather the weeds can be pulled out without harming the surface of the lawn.
