Part 8

We weaken our plants, as we do ourselves, by keeping the temperature of our rooms too high. We are not satisfied with a comfortable warmth. We want heat enough to keep us constantly conscious of it by its intensity. This is all wrong from the health point of view. What ought to be done is to install a thermometer in every room, and so regulate the amount of heat that all are kept at summer warmth by arranging for a system of ventilation that will act automatically when the thermometer goes above a certain point. This system is speedily coming into general use, and gives most excellent satisfaction. Where it is not in use, the temperature can be kept somewhere near where it ought to be by opening doors or windows from time to time, as already spoken of. Keep in mind that too much heat and too little fresh air will kill almost any plant in time, and the two, working together, will, nine times out of ten, make any window-garden a comparative failure.

Care must be taken in watering plants in winter. Those which are dormant, or are making but little growth, will require very little water. Those in active growth will need more. The only way to tell how much to give is to watch your plants closely, and observe the effect of the applications given. When the surface of the soil takes on a dry look it is safe to conclude that the roots of the plant in the pot have made use of most of the moisture in it, and that more water should be given. Then give enough to make the soil moist all through, and withhold further applications until the dry look appears again. Never form the habit of watering your plants every time you happen to think about it, and then apply just enough to make the soil look wet on its surface. If this is done you will never grow good plants, for only the surface roots will get the moisture they need. Have a stated time for watering, and let the appearance of the soil govern the amount used.

THE INSECT ENEMIES OF PLANTS

Every woman who attempts to grow flowers in the house will sooner or later have to wage warfare against insects.

Perhaps the first battle will have to be fought with the aphis, or plant-louse. This insect sucks the sap--the life-blood of the plant--from stalk and leaf, and soon, if let alone, it will exhaust the vitality of the plant to a degree that is wholly incompatible with health. In fact, if allowed to have its way, it will kill your plants, for it propagates its species with such rapidity that a plant will soon be literally covered with them. We used to kill off these insects by fumigating the plants infested with them with tobacco smoke, and in doing it we made ourselves about as sick as the insects were, and the nauseating fumes of it clung to everything in and about the house for days. Nowadays we make use of the nicotine principle of tobacco in our warfare against the aphis, but in a manner that leaves out the objectionable features of fumigation. Tobacco manufacturers have prepared an extract of the nicotine in the plant, and put it on the market under the name of nicoticide. All we have to do when we want to make use of it is to put a small quantity in water, and spray our plants with the mixture. Every aphis that it touches will die, and those that it fails to reach will take the hint that they are not wanted and that their presence will not long be tolerated, and the first you know they will have disappeared.

Instead of waiting for the attack of the enemy I consider it good policy to anticipate it by frequent applications of the tobacco-bath. It will be found easier to keep the enemy away than to rout it after it has established itself on your plants.

The red spider is another insect that does deadly work in the window-garden, especially in rooms where the temperature is high and there is little moisture in the air--a condition that generally prevails in the ordinary living-room. This pest is so small that its presence is seldom suspected until considerable injury has been done to the plants it works on. If you notice that leaves are turning yellow and dropping off, and that more and more of them fall each day, you had better look into the matter. Examine some of the fallen leaves. If you find tiny webs on the under side of them you may be quite sure that the spider is responsible for the condition your plants are in. Look at some of the leaves that are yellowing, but have not yet let go their hold, and you will be quite likely to find little red specks on them. These specks resemble grains of fine Cayenne pepper more than anything else. Watch them for a while and you will find that they are living organisms. It seems hardly possible that such tiny creatures can do much harm to a strong plant, but the fact is that there is no more voracious enemy of plant life in existence. Here the tobacco-bath does not come in play. Cold water is all the insecticide we need. Spray it over every portion of the infested plants daily, until they again take on a healthy look and begin to grow. The spider will not stay long in a moist atmosphere. Make it moist and keep it so by the liberal use of water sprayed upon your plants, and you will have very little trouble with this dangerous pest. But if you neglect to use water regularly and freely the probabilities are that your window-garden will look rather sickly by spring.

Scale is an insect that often attacks plants having thick, firm-textured foliage, like the oleander, lemon, ivy, ficus, and palm. It is a flat creature, looking more like a fish-scale than anything else, hence its name. It attaches itself to the leaf and sucks the life out of it. The best weapon to fight this enemy with is an emulsion made as follows: shave thinly half a pound of white soap; pour a little water over it and set it on the stove to liquefy. When the soap is melted, add to it a pint of water and bring to a boil. When boiling, add a teacupful of kerosene and three tablespoonfuls of the tobacco extract. These ingredients, under the effect of heat, will form an emulsion that will unite readily with water. Use in the proportion of one part emulsion to fifteen parts water. Apply to the infested plants with a soft cloth or a camel's-hair brush. Be sure that some of it gets to all parts of the plant. Two or three applications may be necessary. Prepare a quantity of it and keep it on hand for use when needed.

The emulsion spoken of above is an excellent remedy for the ills the rose is heir to during the early part of the season. If Paris green is sprayed onto the plants the foliage is frequently burned by it. If kerosene is mixed with water and applied, the oil will seldom emulsify perfectly with the water, and wherever a drop of it falls on leaf or bud it will do quite as much damage as would the bug or worm you are fighting. Hellebore is never to be depended on. The kerosene-tobacco-soap emulsion will be found safe and effective.

Worms in the soil of pot plants can be got rid of by the use of lime-water. Put a piece of perfectly fresh lime as large as the ordinary coffee-cup in ten quarts of water. If fresh, as it must be to be of any benefit, the water will seem to boil for a little while. By and by a white sediment will settle to the bottom of the vessel, and the water above will be clear. Pour this off and apply enough of it to each plant to saturate all the soil in the pot. Plug up the drainage hole in the bottom of the pot before the application is made, that the water may be retained long enough to do its work. Repeat the application if necessary.

GARDENING FOR CHILDREN

If you want to keep children out of mischief give them a little garden. One that they can call their own will afford them far more pleasure than they get out of working in your garden. Of course they will not be expected to go ahead with garden work at first and make much success at it without assistance from some one, and by object-lessons, but they will soon master the fundamental points of it, and when they have done that they will surprise you by the facility with which they pick up the information that grows out of their early experience and the amount of work that they will accomplish all by themselves.

And you will be pleased to see how interested they are in the new undertaking. It will not seem like work to them. It will be play, and play of such a healthy character that you can well afford to ignore soiled clothes, and hands that have caught the grime of the soil, and faces on which sweat and soil have met on common ground and formed an intimate partnership. The healthy color of the faces of the children who work out of doors, and the excellent appetites that they bring to the table, will convince you that gardening is the best of all tonics for them.

And you will be gratified to know that they are learning more from the great book of Nature than they would ever learn in the schools. They are learning things at first hand, for Nature will take charge of the little pupils and not trust her kindergarten work to an assistant. Nine children out of ten who have a garden to work in will become more interested in it than in all the fairy-books that were ever written. For are not the processes of germination and growth going on before their eyes akin to magic? The miracle of life is being performed before them every day, and they are taking part in it. That is what will make it so delightful to them. They have formed a partnership with Nature in miracle-making.

Parents who have only a hazy notion of garden-work may think themselves incompetent to teach their children. But if they set out to do so they will soon find that they are daily learning enough to make them safe teachers for the little folks. And the best of it will be that they themselves are getting quite as much good and pleasure out of it as the children are.

Give the boys and girls good tools to work with. Never ask them to make use of those you have worn out or found worthless. Something quite as good as you would provide for yourself is what should be provided for them. They will appreciate a good thing, be very sure, and the fact that they have it will be one of the best possible incentives to work. Supply them with good seed. And do not fail to encourage them by giving all the credit justly due them for what they accomplish. Children like to know that their efforts are properly appreciated. We grownups and the children are very much alike in that respect.

HOME AND GARDEN CONVENIENCES

There are many ways in which work in the garden and about the home can be varied in such a manner as to give a variety of comparatively new and pleasing effects with so little trouble and expense that the amateur gardener and home-maker who would like "something new" will, I feel sure, be delighted to undertake some of them.

One is a floral awning for the windows which are exposed to strong sunshine. A frame is made of lath, the width of the window and half its depth, by nailing four of the strips together in a square and then fastening other strips across it in a diamond or lattice fashion. Attach this frame to the top of the window-casing by door-butts. Then push the lower part of it away from the window until you have it at the angle at which a cloth awning would hang when dropped, and support it in that position by running strips of wood from each corner to the sides of the window-frame.

If such vines as morning-glory, flowering bean, and cypress are trained up each side of the window until they reach these supports, it will be an easy matter to coax them up them and from them to the awning's framework, which they will soon cover with foliage and flowers. Such an awning will be found quite as satisfactory as one of cloth, so far as shade is concerned, and, as for beauty, there is no comparison between them, for the ordinary awning of striped cloth is never ornamental. A floral awning is to the upper part of the window what the window-box of plants is to the lower portion of it, and the two can be used in combination with most delightful results. Indeed, they belong together, and one without the other only half carries out the scheme of window decoration.

Such awnings will be found as satisfactory for exposed doors as for windows. The boys of the family--or the women of it--can make them and put them in place, and the cost of them will be so small, compared with their ornamental and practical value, that one season's trial of them will make them permanent features of home-beautifying thereafter. I would advise planing the strips of lath and giving the frames a coat of green or white paint before putting them in place. Green paint will make them unobtrusive, and white will give a pleasing color contrast. If they are taken down in fall and stored in a dry place over winter they will last for a good many seasons.

As a general thing the front gate, if there is one, is not particularly ornamental. But it can easily be made so by setting posts ten or twelve feet tall at either side, and attaching to the top of them a double awning-frame similar to that advised for windows. Let these frames meet at the top and slope outward and downward, roof fashion, and have supports running to each outer corner from the posts. When vines are trained up the posts and over the frames, and are allowed to droop in graceful festoons of foliage and flower from them, the effect will be charming. Here is where the wild cucumber--the most rapid climber of all our annuals--will be able to do most effective work. I would advise the use of hardy vines for positions of this kind, as they will be attractive from the beginning of the season, while an annual has to be given considerable time to grow before it becomes equal to the task assigned it.

Garden-seats ought to be a feature of all home grounds large enough to admit of them. And these seats can be made as ornamental as the gateway just described by providing them with awnings large enough to afford complete shade. Of course, where there are trees to furnish shade such awnings will not be needed--and the logical place for a garden-seat is under a tree, if there is one--but on grounds where there are no trees to furnish shade, such protection from the heat of summer sunshine as these awnings will afford becomes more a necessity than a luxury. As it is, they are both ornamental and useful, and the ease and cheapness with which they are made commends them to all who believe in the value of "little things" in making home attractive and pleasant.

Often it is desirable to furnish certain portions of the home grounds with screens large enough to shut off the public view. These should have frames of a size that guarantees strength. Lath put on in lattice fashion will make a good covering for them, but it will not be strong enough to insure durability in itself, hence the necessity of a more substantial framework. It is always advisable to paint them before covering them with vines. As screens of this kind are generally built with a view to permanence, I would advise covering them with hardy vines, like ampelopsis, Clematis flammula and C. paniculata, aristolochia, or trumpet honeysuckle.
