Tomatoes for home gardens

Tomatoes are one of the most popular garden vegetables. Many different tomato types, varieties and shapes are available for gardening.

Tomatoes do best if started indoors from seed six to eight weeks before planting. For an early crop, plant tomatoes as soon as the danger of frost is past. Popular varieties of tomatoes are available at nurseries and garden centers as bedding plants, or transplants. The four consistently performing tomato varieties for this area are Big Beef, Celebrity, Early Girl and Medina. When buying transplants, remember that, for healthy plants, the condition of the plant is more important than the variety.

Tomatoes for home gardensTomatoes perform best in a warm, rich, deep garden soil and have an extensive root system. Add a one-inch layer of organic material to the tomato-bed soil and mix it in deeply. Fertilize the area before planting tomatoes. Warm the soil using black fabric mulch, or plant tomatoes on the south side of buildings that are warmed by the sun.

If there's a possibility of frost, protect the plants with hot caps, plastic covers, boxes or baskets. Remember to remove this protection each morning to vent the plants and prevent over-heating.

A poor crop can be caused by night temperatures below 50 degrees Farenheit when pollen isn't produced in sufficient quantities. Once tomatoes form, avoid fluctuations in soil moisture to prevent blossom end rot, a disorder related to watering and the movement of nutrients into the plant.

To hurry the ripening of tomatoes, withhold water a bit, but avoid prolonged wilting of the plant. When frost threatens in autumn, cover plants or cut them off at ground level and hang them upside down indoors so tomatoes continue to ripen on the vine.

For "Organic soil amendments" refer to message number 1604.
