Culinary Herbs: Their Cultivation Harvesting Curing and Uses

by M. G. Kains

In the home garden, parsley may be sown as an edging for flower beds and borders. For such purpose it is best to sow the seed thickly during late October or November in double rows close together, say 3 or 4 inches. Sown at that time, the plants may be expected to appear earlier than if spring sown and to form a ribbon of verdure which will remain green not only all the growing season, but well into winter if desired. It is best, however, to dig them up in the fall and resow for the year succeeding.

For window culture, all that is needed is a box filled with rich soil. The roots may be dug in the fall and planted in the box. A sunny window is best, but any window will do. If space is at a premium, a nail keg may be made to yield a large amount of leaves. Not only may the tops be filled with plants, but the sides also. Holes should be bored in the staves about 4 inches apart. (See illustration, [page 2].) A layer of earth is placed in the bottom as deep as the lowest tier of holes. Then roots are pushed through these holes and a second layer of earth put in. The process is repeated till the keg is full. Then plants are set on the top. As the keg is being filled the earth should be packed very firmly, both around the plants and in the keg. When full the soil should be thoroughly soaked and allowed to drain before being taken to the window. To insure a supply of water for all the plants, a short piece of pipe should be placed in the center of the keg so as to reach about half way toward the bottom. This will enable water to reach the plants placed in the lower tiers of holes. If the leaves look yellow at any time, they may need water or a little manure water.

As parsley is grown for its leaves, it can scarcely be over fertilized. Like cabbage, but, of course, upon a smaller scale, it is a gross feeder. It demands that plenty of nitrogenous food be in the soil. That is, the soil should be well supplied with humus, preferably derived from decaying leguminous crops or from stable manure. A favorite commercial fertilizer for parsley consists of 3 per cent nitrogen, 8 per cent potash and 9 per cent phosphoric acid applied in the drills at the rate of 600 to 900 pounds to the acre in two or three applications—especially the nitrogen, to supply which nitrate of soda is the most popular material.

A common practice among market gardeners in the neighborhood of New York has been to sow the seed in their cold frames between rows of lettuce transplanted during March or early April. The lettuce is cut in May, by which time the parsley is getting up. When grown by this plan the crop may be secured four or five weeks earlier than if the seed is sown in the open ground. The first cutting may be made during June. After this first cutting has been made the market usually becomes overstocked and the price falls, so many growers do not cut again until early September when they cut and destroy the leaves preparatory to securing an autumn and winter supply.

When the weather becomes cool and when the plants have developed a new and sturdy rosette of leaves, they are transplanted in shallow trenches either in cold frames, in cool greenhouses (lettuce and violet houses), under the benches of greenhouses, or, in fact, any convenient place that is not likely to prove satisfactory for growing plants that require more heat and light.

This method, it must be said, is not now as popular near the large cities as before the development of the great trucking fields in the Atlantic coast states; but it is a thoroughly practical plan and well worth practicing in the neighborhood of smaller cities and towns not adequately supplied with this garnishing and flavoring herb.

A fair return from a cold frame to which the plants have been transplanted ranges from $3 to $7 during the winter months. Since many sashes are stored during this season, such a possible return deserves to be considered. The total annual yield from an acre by this method may vary from $500 to $800 or even more—gross. By the ordinary field method from $150 to $300 is the usual range. Instead of throwing away the leaves cut in September, it should be profitable to dry these leaves and sell them in tins or jars for flavoring.

When it is desired to supply the demand for American seed, which is preferred to European, the plants may be managed in any of the ways already mentioned, either allowed to remain in the field or transplanted to cold frames, or greenhouses. If left in the field, they should be partially buried with litter or coarse manure. As the ground will not be occupied more than a third of the second season, a crop of early beets, forcing carrots, radishes, lettuce or some other quick-maturing crop may be sown between the rows of parsley plants. Such crops will mature by the time the parsley seed is harvested in late May or early June, and the ground can then be plowed and fitted for some late crop such as early maturing but late-sown sweet corn, celery, dwarf peas, late beets or string beans.

When seed is desired, every imperfect or undesirable plant should be rooted out and destroyed, so that none but the best can fertilize each other. In early spring the litter must be either removed from the plants and the ground between the rows given a cultivation to loosen the surface, or it may be raked between the rows and allowed to remain until after seed harvest. In this latter case, of course, no other crop can be grown.

Like celery seed, parsley seed ripens very irregularly, some umbels being ready to cut from one to three weeks earlier than others. This quality of the plant may be bred out by keeping the earliest maturing seed separate from the later maturing and choosing this for producing subsequent seed crops. By such selection one to three weeks may be saved in later seasons, a saving of time not to be ignored in gardening operations.
