COMMON WEEDS
What a delight it would be if we could garden without weeds. But that is well-nigh impossible. For these rascals, the weeds, are such persistent fellows, so clever in their devices for getting over the surface of the earth, so able to live where nothing else in the plant world can live, that it is a discouraging matter to attempt to exterminate them. They always seem to me like pushing sort of people trying to live among those who do not want them. Then, too, they crowd the better class of inhabitants out.
"There are a certain number of plants which we always looked upon as weeds, such as burdock and wild carrot, for example. But if a beautiful garden plant should persist in living and spreading itself over our vegetable garden, then that, too, would become a weed. Over across the sea in England the poppy grows wild in the fields. It looks very beautiful to the traveler, because it makes lovely red splashes of colour through the field. But I doubt very much if it looks really attractive to the farmer. These things depend largely, do they not, upon one's point of view?
"Even a question like weeds we have no right to look at from one point of view only. The good points of weeds do not balance up the bad points; but it is well to give even weeds their due. Rid the world of weeds and unless these despoiled spots were cultivated, think of the great waste places there would be over the earth's surface. The weeds shade the ground thus preventing too great surface evaporation. Then the weeds are a signal to farmers and all gardeners to get busy. We people of the world are lazy, just naturally so, and perhaps if there were no weeds we might cultivate the soil too little. Years ago certain weeds were much used in medicine. This is more or less true, to-day. The dandelion with its bitter secretion was good, it was believed, for the liver, a sort of spring tonic. The Department of Agriculture has printed a pamphlet on 'Weeds Used in Medicine' (Farmers' Bulletin, No. 188). Jack and Jay each sent for a copy last spring. You all might start a garden library with these pamphlets for a basis. They are sent to you free and are invaluable in your work. Get together all the helps you can on the subject you are studying. Boys and girls receive free so much in the present day that it seems a shame not to make use of these things. The boys have written to the Department of Agriculture and each month it sends to the club a list of the publications sent out or reprinted during the previous month. You girls might follow this good example set you by the boys.
"Well, we have wandered a bit from the subject in hand. Weeds are again discouraging because they have such facilities for travel. Talk about flying machines—weeds are centuries ahead of men along these lines. Look at a milkweed seed; it is a complete flying apparatus. With its perfect ballast it flies beautifully along over field and river ready to alight in proper seed style, end down.
"There is a piece of mechanism in the end of each burdock seed that seems to make travel possible, and dissemination sure. Never was fish hook more cleverly made than this hook of the bur seed. It catches on to your clothing and travels until you feel its pull. Then you pick it off and cast it aside. So it goes. It sticks to the furry and hairy coats of animals and again is carried along.
"Did you ever observe the seed of wild carrot? It, too, is arranged with clinging points all around and about its seed. If you should give just a little attention to the subject of the means of distribution of wild seeds you would have a greater respect for the ways and means of Nature.
"Here is another discouraging side to the weed question. Weeds produce so many, many seeds! Look at a single stalk of plantain. This stalk does not stand for one seed capsule, but all up and down the stalk are the seeds; again, not one seed here and one there, but each capsule or seed case holding many seeds. When these become ripe, then the top of the capsule comes off just like the cover of a box, or the top of a salt cellar, and the seeds are sent out. It would not be a useless thing to count sometimes the number of seeds on one plantain stalk, and thus gain an idea of the tremendous possibilities of increase which the weeds have.
"A lad I once knew counted the number of seeds in a milkweed pod which he had, and found very nearly two hundred. I do not remember the exact number. It was between one hundred and ninety-five and two hundred. Think of one pod scattering that number of seeds! Think again of the number of pods on one milkweed plant! It is staggering, is it not? To be sure we can remember the parable of the sower and have some hope, for some seed may fall on soil in which they will never come to maturity.
"Weeds, like the wild morning glory, form new plants not from their seed only, but from their travelling, trailing branches.
"If, then, the chances are so good for renewal of weeds, what is the plan of campaign which we should follow? Once a German gentleman who loved and cultivated roses was asked how to get rid of rose bugs. 'Kill them,' he said. 'Pick them off by hand and kill them by foot is the sure method!' he continued.
"So, to get rid of weeds, just destroy them. Persistently and constantly weed them out and cultivate the soil. Clean cultivation is the only sort for good crops and freedom from weeds.
"Weeds, as flowers, drop in the three classes of annuals, biennials and perennials. Any annual is easy enough to hold down. Just pull such weeds up. Some merely cut the weed off at the surface of the ground, but it is a better way to be rid of the thing entirely. And should you not be quite sure of the kind of weed, then pulling up is the only really safe plan. For if the weed happened to be a perennial, leaving the root in the ground would be the worst possible thing to do.
"The greatest business of all annuals is to form seed. Now I know you wish to say that this is the business of all plants. It is. But with annuals there is only one chance to produce seed. That chance is the one short year of their lives, and this is doubtless the reason why these chaps work so hard at seed forming, and produce so many seed. Therefore, the thing evidently to be done is to make it impossible for annuals to form seed.
"The biennials and perennials must have further treatment than just that of preventing seed formation. The underground part of such weeds must be destroyed. For these live in the ground ready to come up again. Biennials may be killed out by deep hoeing. Get rid of all the young plants, keep at the older ones with the hoe and prevent seed formation, too. Biennials are found most abundantly in waste places along woodsides and where the soil for a long time has been left undisturbed.
"Perennials need about the same treatment as biennials. But even greater persistency should be exercised in destroying the underground portion. For these underground plants produce new plants as surely as seeds do. The bindweed has a creeping root, wild garlic has a bulb, and such forms are always producing new forms underground while the seed above the ground is able to do the same thing.
"Ploughing helps destroy perennials, as the roots are exposed to direct sunlight and so destroyed. Another method of treatment is that of cutting off the top down to the root and putting salt on the freshly cut root tap. Then again these roots may be starved out by never allowing the top or leafy part to form. You will remember that it is the leaf which makes the food. And if there is no food then there will be none to store away in the root for new root formation. Some farmers smother roots. This is done by planting such crops as hemp, clover or cowpeas. These crops choke out the weeds. They cover the ground very completely, and so the weeds have less of a chance.
"I give the following table of a few very common weeds in order that you may know just how to handle them.
"I must speak especially about snapdragon or butter and eggs. It came to our country as a garden flower. It has spread and spread, partly by its seeds and partly by its root stalks, which are creeping ones, and now it is a perennial weed. For since it has become a nuisance it must be classed as a weed. As it spreads along it tends to force out other plants.
"This weed, like the wild carrot, is really very lovely. Could such weeds be properly held down in small garden areas they would be very ornamental. I saw a little flower garden once, quite beautiful, with two small clumps, one of wild mustard and one of field daisy, among the other flowers.

"The seeds of the wild mustard, like those of the plantain and other weeds, get in with the grain seed and so cause constant trouble. Farmers feel that such weeds must be thoroughly gotten out of the fields.
"It is not our own native weeds which are so troublesome but the foreign ones. Most of our worst weeds are foreigners. They have come to this country as stowaways from across the seas. They have fought for centuries and can keep the fight up over here.
"I am not going to give you a description of each weed we have. This table, a copy of which is for each of you, will be, I think, of true help. The study of weeds is something quite by itself. It is for you to help prevent the seeding of weeds everywhere. Do not carelessly scatter seeds. Keep your own garden plots free from these pests by clean and careful cultivation. Remember, too, the value of cover crops.
"There is another pest to fight. This pest is of the animal kingdom and not of the plant kingdom. Next Friday our talk is on animal pests, and how to destroy them."
