If it so happens that the soil is not very fertile and there is only a limited quantity of fertilizer available, it is a good plan, instead of spreading it all over the plot, to apply it only in close proximity to the hills or drills in which the plants are growing.
It is important to remember that the greatest good can only be obtained from chemical fertilizers when the soil is plentifully supplied with humus.
VI THE KINDS OF VEGETABLES TO GROW
A number of factors have to be taken into consideration before deciding just which kinds of vegetables to plant in your garden. Some of these factors are: the nature of the soil, the size of the garden, the food value of the crop and the ease with which it may be stored for winter use.
Sometimes it is possible to adapt the soil to the crop, but usually it is easier to adapt the crop to the soil. A rich loam will support practically all of the vegetables and produce good crops. A thin, sandy soil which has not been properly fertilized is only suitable for such crops as bush beans, beets, Swiss chard, tomato, and New Zealand spinach. Of course other crops can be grown on such a soil, but not very satisfactorily. Potatoes like a sandy soil, but it must be well fertilized.
Heavy clay soils will grow cabbage, kale, corn, parsley, parsnips (if the soil is deep), peas and rhubarb.
If the soil is shallow it is not advisable to attempt any of the root crops that make a long root. In this category belong the long beets, parsnips, and salsify.
That person is unwise who attempts to grow potatoes, corn, and cabbage in a very restricted area. These crops need plenty of room in which to develop, and when one has only a city back yard, or a small plot, it is better to concentrate on the smaller-growing vegetables. The best crops to grow in the city back yard are bush beans, parsley, radish, beets, Swiss chard, and tomato. Peas would probably succeed if it were not for the sparrows which pick off the leaves as fast as they are produced.
One is strictly limited if the available ground is shaded. All the vegetables need sun for the greater part of the day. Those kinds which are grown for their leaves are more satisfactory in a shady garden, and if the soil conditions are favorable the following may be tried: beet, cabbage, lettuce, and Swiss chard. Even these need a few hours of sunshine.
Those who are interested in dietetics may wish to choose their vegetables on the basis of their food value. In terms of the calorie, the unit of energy as applied to food, we find that 1 ounce of dried beans (seeds) and 8 ounces of string-beans are required to produce a hundred calories. Of green corn 3.2 ounces are needed; of potatoes, 5.3 ounces; of onions, 8 ounces; of beets, 9.6 ounces; of cabbage, 13.3 ounces; and at the bottom of the list comes celery, of which 23.7 ounces are required to produce a hundred calories. It is misleading, however, to take a list of vegetables with their caloric values and decide, that because 6.4 ounces of peas contain one hundred calories, while it is necessary to have 10.1 ounces of carrots to produce the same amount, nothing but peas shall be grown in the garden. The proper basis on which to make a decision along these lines is on the amount of calories that can be obtained from each square yard of ground. A considerable area is necessary for the production of a pound of peas, while a similar weight of carrots could be produced in a much smaller space. Furthermore, it must be remembered that the human system demands a certain amount of bulky foods, and these are supplied by vegetables low in caloric values.
There are a number of crops that can easily be preserved or stored for winter use, and this should be considered when deciding what kinds of vegetables to grow. String-beans are easily preserved by pickling them in brine, and there is no difficulty whatever in caring for the dry-shell beans when they are not infested with weevils. All of the root crops—carrots, beets, parsnips—can be easily stored in sand or soil in the cellar, and potatoes are one of the easiest of crops to care for. Onions can readily be carried over into the winter if a cool, airy room is available. All of the crops just mentioned are fairly high in food value.
VII PLANNING THE GARDEN
A garden can be made without a plan, but it is usually a haphazard sort of affair, and it frequently means that much more money is spent for seeds than is necessary. Another frequent happening in a miss-or-hit garden of this kind is a plethora of some kinds of vegetables and a great scarcity of others.
It is difficult to give any definite information as to the quantities of vegetables to grow, as yields vary so much, owing to the character of the soil and climate, the variety of the vegetable, and the skill, or lack of it, of the gardener. The preferences of the individual must also be considered. The table in the Appendix giving the approximate amount of vegetables that can be obtained from a hundred-foot row may be helpful. It must be remembered, however, that these figures are only approximate and that wide variations can be expected.
When planning your garden you must take into consideration the sunshine it receives, and if part of it is shaded reserve that part for those crops that will endure shade. If there is any variation in the nature of the soil, whether in regard to its physical condition, fertility, or wetness, you should place the crops accordingly.
As a general rule the rows should run north and south, as by this plan each row receives its share of sunlight. If for any reason this is not practicable, put the tall-growing crops at the north end of the plot, so that they do not shade the smaller kinds. The perennial crops, like asparagus and rhubarb, are best placed at one end or side of the plot so that they are not in the way when digging or plowing is being done. It makes a better-looking plot if those vegetables which are planted the same distance apart are grouped together.
Plan to have the ground occupied for the whole season. Many vegetables take a comparatively short time in which to mature, and these can be removed when harvested and the ground occupied by another crop. Thus peas can be followed by cauliflower or cabbage, early beets by beans, lettuce by tomato, and so on. Find out the average number of growing-days in your locality and consult the table in the Appendix giving the number of days required to bring the various crops to maturity.
When planning for succession vegetables, have some regard to crop rotation. That is to say, if the ground in the early part of the season has been occupied by a leaf crop, follow it by a fruit crop, or vice versa. Early cabbage followed by beans may be cited as an example. Similarly, root crops may be followed by leaf crops, as early carrots and fall spinach.
Another important reason for crop rotation is that it lessens the danger of loss from disease. Many of the fungous diseases of plants are carried over from year to year in the soil. Some of them are able to live on only one particular host plant, and if that crop is not grown in the soil where the fungus is hibernating the disease ultimately dies out through lack of food.
The first thing to do in planning a vegetable-garden is to measure the plot and transfer its outlines to scale on paper. Then, bearing in mind the considerations just outlined in this chapter, decide on the kinds of vegetables you wish to grow. Now the real fun of planning begins! The desires of the grower as to quantities and variety of vegetables must be scaled down so as to fit the plot. Take a ruler and draw lines across your plan to represent the rows of vegetables. The distance between the rows may be drawn to scale to correspond with the actual distance between the rows on the ground, or you may merely note the theoretical distance between the lines. Write the name of the vegetable on each line, with that of the succession crop, if any. It is a good idea to mount your plan on stiff cardboard when finished, and to allow a space either at the side or on the back for making notes to be taken during the growing-season. These notes may consist of reminders that such and such a crop is not suited in its present location, the time occupied from seed-sowing to maturity, the desirability or otherwise of certain vegetables, etc.

VIII SEEDS, SEED-SOWING, AND TRANSPLANTING
Most seeds, with the exception of carrot, onion, parsnip, and parsley, will grow fairly satisfactorily even if they are more than one year old, so that left-overs from the preceding year may be planted with good results. Before using these left-over seeds, however, it is wise to test their germinating power before committing them to the garden. To plant seeds which will not germinate is a waste of time and labor. Testing the viability of seeds is a simple and easy matter and very advisable if there is any doubt. Count out fifty or one hundred seeds of the kind that you wish to test and plant them in sand or earth in a cigar-box or something similar. Place them in a fairly warm room (temperature about 60° Fahr.) and keep the soil moist. In a week or two take note of the number which have sprouted, and this will give you the percentage of good seeds and some idea of the quantity you will have to plant in order to get a good stand. For instance, if only 50 per cent. of the seeds germinate it means that it will be necessary to plant double the usual number to make sure of having a sufficient number of plants. Another and less messy way of testing seeds is to place them on a plate between blotters or cloth, which must be kept moist, covering them with another plate to prevent too rapid evaporation of moisture. Although they adequately furnish the desired information, neither of these methods of testing seeds gives an absolutely accurate indication of what will take place when they are planted in the garden. Seeds out of doors are exposed to a number of hazards that are not present under indoor conditions.
Before planting any seeds outdoors the soil must be in the proper condition. It must not be so wet that it sticks to the tools used, the surface must be finely pulverized with a rake, and all large stones taken off.
There are three ways of planting seeds outdoors—in drills, in hills, and broadcast. The drills consist of shallow trenches from one-half inch to two inches deep, in which the seeds are sown. The young plants are later thinned out so that they stand an equal distance apart.
Seeds are said to be planted in hills when they are sown in such a way that the resultant plants are in groups of three or more standing the same distance in the rows as the distance between the rows.
Broadcast sowing is when the seeds are scattered over the surface of the ground and covered by raking them in, or by sprinkling soil over them.
