Growing the Tomato Plant

Growing the Tomato Plant
To manage a crop, one must needs know the plant. To know the various characters of the tomato helps one to master its culture.

The tomato belongs to the night shade family, the Solanaceae of the botanist, along with the potato, tobacco, petunia, pepper, eggplant, night shade, jimson weed and many other plants useful and noxious.

The tomato is a warm-season crop, sensitive to frost but reasonably resistant to heat and drought, thriving under a wide range of climate and soil. A frost free season of seventy-five to ninety days will mature home garden tomatoes in useful quantities if good plants are set but over 120 days are needed for economical commercial production. Plant growing requires six to eight weeks previous to setting out-of-doors. Each fruit requires about six weeks from blossom to ripeness. The fruit ripens best for yield, color and quality when the weather is warm and sunny. Low temperatures without frost are not favorable for growth and prolonged conditions of this sort may "check" the plant and retard the response when higher temperatures come.

The tomato is sensitive to extreme day-length, setting fruit at 7 to 19 hours but not at 5 or 24 hours.

The tomato responds readily to fertilizers and to moisture, coming quickly into vigorous growth after unfavorable conditions, unless too badly stunted.

As long as moisture and nutrients are available and other conditions are favorable, a tomato plant will continue to branch and blossom and make fruit almost indefinitely. A pruned single stem plant in a greenhouse at Cornell once reached a length of over 40 feet during a year and a half of growth. Thus, it is really a herbaceous perennial grown in northern climates as an annual.

The plant branches freely at leaf joints but fruit clusters are formed along the bare stem,—a habit not common among plants. Some varieties are "determinate" in habit, sometimes miscalled "self-pruning," as branches only attain limited length.
