Weeds. Many very strong Weeds are a compliment to one’s soil: only good soil produces them. But they are not a compliment to one’s tillage. If the soil is well prepared and well tilled to conserve moisture and to unlock plant-food ([see Tillage]), Weeds will find little chance of growing. Stir the ground often: it benefits the ground and keeps out the Weeds. Plant vegetables in long straight rows rather than in beds, for thereby tillage is made easier. For beds and for small plants, the hand-weeders (as shown in the margin) are very efficient. They save laborious finger-work. Weed seeds are often distributed in manure, especially if Weeds have been allowed to grow and ripen on the piles. See that pernicious Weeds do not seed about the premises. For the treatment of weedy lawns, see the article [Lawns].
Windbreaks. There is the greatest difference of opinion as to the value of Windbreaks for fruit plantations. These differences arise from the fact that a Windbreak may be of great benefit in one place, but a disadvantage in another. It is always advisable to break the force of very strong winds, for such winds tend to injure the trees when laden with fruit or ice, and they blow off the fruit; and in dry countries they cause the soil to become parched. If the wind is usually warmer than the area, however, particularly in the winter time, it is better not to stop it, but to allow it to circulate through the plantation. This is the case in areas which lie close to large bodies of water. The wind coming off the water is warmer than that off the land, and tends thereby to protect the fruit plantation from severe cold. A circulation of air is desirable in late spring and early fall in order to avoid the still frosts. Therefore, if the area is very closely surrounded by dense plantations, it may have what the fruit-growers call “stagnant air;” but thinning out the Windbreak on one or two sides, or cutting holes through it, may allow the air to move through, thereby affording atmospheric drainage and insuring greater immunity from the light local frosts.
It is ordinarily better to break the force of the winds than to stop or deflect them. That is, the Windbreak may be thin enough to allow the wind to take its normal direction, but its force is broken. A stone wall or a very dense hedge of evergreens may cause the wind to rise over the plantation or to be deflected to one side; and this, in many cases, as already said, may be a decided disadvantage. The philosophy of a good Windbreak for fruit plantations may be summed up in this way: the force of heavy winds should be broken; warm winds should be allowed to circulate freely through the plantation; still air should be avoided.
Ordinarily, one or two rows of deciduous trees are sufficient protection. When the plantation is very much exposed to very cold or land winds, a thick evergreen screen may be a decided advantage. It is usually better to have the heavy Windbreak on the upper side of the area, so that it may not interfere with the natural drainage of the cold air down the slope. In making a Windbreak, it is important that those trees be chosen which will not become harboring places for orchard enemies. The wild cherry, for example, is inveterately attacked by the tent caterpillar, and the wild crabs and wild plums are likely to breed orchard insects. If the Windbreak is planted some time in advance of the orchard, the row of fruit trees next the Windbreak will be very likely to suffer from lack of moisture and food.
A different type of Windbreak is that which is desired for a shelter belt about the home grounds. The matter of atmospheric drainage does not enter into this problem to any great extent. Such shelter belt is usually placed at the extreme edge of the home yard, toward the heaviest or prevailing wind. It may be a dense plantation of evergreens. If so, the Norway spruce is one of the best for general purposes. For a lower belt, the arborvitæ is excellent. Some of the pines, as the Scotch or Austrian, are also to be advised, particularly if the belt is at some distance from the residence. As a rule, the coarser the tree the farther it should be placed from the house.
Persons may desire to use the Windbreak as a screen to hide undesirable objects. If these objects are of a permanent character, as a barn or an unkempt property, evergreen trees should be used. For temporary screens, any of the very large-growing herbaceous plants may be used. Very excellent subjects are sunflowers, the large-growing nicotianas, castor beans, large varieties of Indian corn, and plants of like growth. Very efficient summer screens may be made with ailanthus, paulownia, basswood, sumac, and other plants which tend to throw up succulent shoots from the base. After these plants have been set a year or two, they are cut back nearly to the ground every winter or spring, and strong shoots are thrown up with great luxuriance during the summer, giving a dense screen and presenting a semi-tropical effect. For such purposes, the roots should be planted only two or three feet apart. If, after a time, the roots become so crowded that the shoots are weak, some of the plants may be removed. Top-dressing the area every fall with manure will tend to make the ground rich enough to afford a very heavy summer growth.
