Preparation of the Soil

With the location of the garden settled, the first step is the preparation of the soil. First, remove anything that would interfere with the plowing or spading of the soil. If the location is the home back yard it is assumed that the ground is free from débris and ready to be broken up. If the garden is to be located on a vacant lot it is probable that there will be stones, broken bricks, tin cans, and other trash to be gotten rid of. If the quantity of trash is not too great it should be hauled to some dump, but if there is so much of it as to make its removal expensive it may be piled on one side or one end of the lot. In some cases stone fences have been built along the outside of lots from the stones that were scattered over the ground. This cleaning-up process requires considerable work and should be done whenever the weather will permit prior to preparation for planting.

The next step in the garden-making process will be to plow or spade the ground. If the land is in sod it should be turned in the fall so that the sods will rot. Heavy clay soils should be turned up loosely and allowed to lie exposed to the freezing and thawing of the winter months. In all cases manure should be turned under if it can be secured. If the surface soil is so hard that it can not be spaded or plowed to advantage a pick or mattock should be used and the ground broken to a depth of 8 or 10 inches. Plenty of manure is about the only thing that will bring a soil of this character into condition. The supply of manure in cities is now quite limited, and the city gardener should make arrangements early in the season to get what he needs. It is assumed that the average back-yard garden is about 30 by 60 feet in size. About 1 ton or one 2-horse load of stable manure can be spaded into the soil of a plat of this size each year. On soil which has not been worked before and which is especially heavy and wanting in organic matter a larger quantity of manure can be used. Street sweepings are not desirable, as they frequently contain considerable oil. Sawdust and planing-mill shavings should not be used on garden land. Leaves may be mixed with heavy soils, but it is best to have them fairly well rotted before they are applied to the land. Early breaking and exposure to frost is the best method of getting land that has not been under cultivation for a number of years in shape for planting. Sandy soils do not benefit by freezing and thawing as do the heavy clay soils, and in all cases precautions must be taken so that the soil will not wash away during heavy rains. It is a very good plan to plow or spade the land in the autumn, sow rye upon it, and then turn the rye under early in the spring.

In regions where the soil is very sandy it is often necessary to keep the surface covered with coarse manure or with some material to prevent it from blowing away. If this precaution is not taken the entire surface soil will be blown off to the depth of the plowing. In the spring the coarser part of the covering should be raked off or turned under before pulverizing and fitting the surface for planting.

Nothing is gained by working the land before it is sufficiently dry in the spring. In sections where the ground freezes hard during winter no harm will be done by plowing it in the fall or during the early winter when quite wet, as the freezing will correct any injury, but land that is worked when too wet in the spring will be injured for the entire season. The usual test is to press a small quantity of the soil in the palm of the hand. If it is too wet for working it will adhere in a solid mass and retain the imprint of the hand, but if dry enough to work it will crumble apart of itself.

When the test shows its fitness for working, land which was plowed or spaded in the fall should be thoroughly harrowed, raked, hoed, or forked over to a depth of 4 or 5 inches, in order to fit it for planting. The more carefully this part of the work is done the easier it will be to care for the crops during the growing season. Land which was not worked in the fall should be plowed or spaded as soon as it dries out sufficiently in the spring, and the top should be thoroughly fitted, as suggested above.

Use of Ashes on Garden Soils

Gardeners frequently ask whether it is advisable to use coal and wood ashes on garden soils. The use of coal ashes on heavy clay soils will tend to lighten them, but the ashes should be screened before they are applied, in order to remove any clinkers or cinders. They should then be spread evenly upon the land and thoroughly mixed with it. Coal ashes have little value as a fertilizer, their use being mainly to loosen the soil and make it more workable.

Wood ashes that are produced by the burning of hard woods, such as oak and hickory, frequently contain as much as 7 per cent of potash and also a little lime and for this reason are a valuable fertilizer. Wood ashes produced by the burning of pine and other soft woods and hardwood ashes that have been exposed to the weather and have had their potash leached from them have comparatively little value as a fertilizer. Not more than 50 pounds of reasonably dry unleached hardwood ashes should be applied to a plat of ground 30 by 60 feet in size, and these should be well mixed with the soil.

Liming Garden Soils

An application of about 12 pecks of hydrated or air-slaked lime to a plat of land 30 by 60 feet in size is advisable in most cases, but there are certain soils that do not need lime. Lime has the effect of loosening and pulverizing heavy clay soils. It also has the effect of sweetening poorly drained soils and those that have a tendency to be sour. It is poor policy, however, to endeavor to remedy conditions resulting from lack of drainage by the application of lime without first providing suitable drainage and removing the cause of the sourness of the soil. Lime should always be applied to the surface soil and not turned under. It should not be applied to land that is to be planted to Irish potatoes, on account of the tendency of the tubers to become infested with scab where lime is present. Perhaps the best method of applying lime to the remainder of the garden is to scatter it over the surface after plowing and before the land is harrowed and fitted for cultivation in the spring. ([Fig. 4].) One application each year is sufficient, and much larger quantities may be applied on heavy clay soils than on light or sandy soils. Lime should never under any circumstances be mixed with commercial fertilizer or with manure, as it liberates the nitrogen contained in them.

Use of Manure on Garden Land

The use of barnyard manure on garden land has already been mentioned, but too much stress can not be placed upon this important point. The most successful commercial gardeners not only follow the practice of plowing or spading under large quantities of manure, but they stack up manure to rot and apply the rotted manure as a top-dressing when fitting the land for planting. Beans, tomatoes, and Irish potatoes may be injured by the use of too much manure, but it is practically impossible to have the land too rich for most garden crops.

Poultry and pigeon manures are excellent fertilizers for the garden but must be used sparingly, as they are very strong and are liable to burn the crops. These manures should be kept under shelter until used and then should be well mixed with the soil, care being taken that no lumps of the manure come in direct contact with the seeds. Not more than 200 pounds of poultry or pigeon manure should be applied to a garden plat 30 by 60 feet in size.

Sheep manure is sold by florists and seedsmen and is an excellent fertilizer for garden crops. Like poultry manure, it is very strong and should be used sparingly. A little pulverized sheep manure sprinkled along the rows and worked into the soil will give the plants a vigorous growth.

Commercial Fertilizers

The use of commercial fertilizers is advisable, especially where plenty of stable or barnyard manure can not be procured. As a rule, fertilizers should be sown broadcast and thoroughly harrowed or raked into the upper 3 inches of soil. Where applied underneath the rows the fertilizer should be well mixed with the soil before the seeds are planted. Great care must be taken in the use of commercial fertilizers in a small garden, as there is always a tendency to use too much and do more injury than good. From 40 to 60 pounds of a standard fertilizer, such as is used by truck gardeners, may be applied to a plot of ground 30 by 60 feet in size.

Commercial fertilizers may be used in very moderate quantities as a side dressing for most growing crops. Nitrate of soda is frequently used in this manner, especially with crops that are grown for their leaf and stem development rather than for fruit. Where used as a side dressing it is best to apply the fertilizer a short distance from the plants but where the small feeder roots will reach it. The fertilizer should be worked into the soil immediately.

It should be remembered that the best results are obtained by the use of commercial fertilizers where there is plenty of manure or organic matter in the soil. All sods and weeds and the remains of garden plants that are not infected with disease should be turned under or composted in one corner of the garden, in order to form material with which to enrich the soil.
