Botanical Name:

Lycopersicon esculentum

Description:

Tomatoes are members of the nightshade family. Originally from South and Central America, today the tomato is grown worldwide for its brightly colored, edible fruits. Red tomatoes contain the pigment lycopene, a well-known antioxidant thought to help prevent some cancers.

Planting Time:

Sow seeds outdoors when air and soil temperatures reach 60F. Set transplants out when nighttime temperatures stay above 50F. Sow seeds indoors 6 to 8 weeks before transplanting.

Exposure:

full sun

Soil:

loose, well-drained, nutrient-rich soil with a pH of 5.5 to 6.8.

Planting:

Plant seedlings in large holes supplemented with kelp and bone meal to provide plants with the extra potassium and phosphorus they need. Allow at least 2 to 3 feet between staked plants in rows spaced 3 feet apart. Sow seeds directly 1/2 inch deep and 2 inches apart. To plant tomatoes in trenches, strip all but the top sets of leaves from plants and place them on their sides in a 2 to 3 inch trench. Firm the soil around the plants and as they grow, the plants will turn upward while the buried stems produce roots. Use this method if transplants are tall and leggy at planting time.
Ad

Containers:

Tomatoes are also well suited to growing in containers. Look for cultivars that are specifically bred to be patio' plants.

Watering:

Keep soil evenly moist (not wet). Water from the ground and early in the day to help prevent disease. Keep plants watered well during dry periods.

Maintenance:

Support plants with stakes or cages if necessary. Snap off any suckers (off-shoots) that appear between the main stem and the stems of the leaves to focus the plant's energy on producing fruit. If your soil is poor in nutrients, feed plants a solution containing fish emulsion once per week until the plants flower. If plants are growing vigorously with dark green leaves, they do not need nitrogen. Too much will increase leaf production and decrease fruit production. On the other hand, yellowing leaves may indicate a need to add nitrogen. Areas with extremely warm summer temperatures may need to protect fruit from sun scald and prevent blossom drop.

Harvesting & Storage:

Tomatoes are ready to harvest when they have developed their full, mature color. Harvest them ripe or while still slightly green and let them ripen at room temperature out of direct sunlight. Cold causes flavor loss so do not refrigerate them. Harvest all remaining tomatoes before the first hard frost. Freeze extras, or if still green, store them in a box filled with newspaper in a dark room (at 55 to 60F) and they will continue to ripen over several weeks.

Diseases and Pests:

Unfortunately, tomatoes are susceptible to damage from a wide variety of insects and diseases. Purchase seeds or plants that are resistant to common tomato diseases and don't plant in areas that have had tomato troubles in the past. Keep soil moisture consistent to help prevent fruit from cracking and water plants early in the day (from the ground) so leaves have time to dry before nightfall. Check for worms and caterpillars that can be picked off by hand and for signs of aphid infestations that can be sprayed off with a hose.

Tips to Success:

Tomatoes cultivars are either determinate (grow to a specific height, flower and produce in short time) or indeterminate (grow, flower and fruit over a long period of time). Determinant tomatoes are good for large crops used for canning. Indeterminate varieties are best if you want to pick tomatoes to eat fresh.

Many of today's tomatoes are hybrids and won't breed true if seeds are saved and planted the following season. If growing plants with the intention of saving seed, choose heirloom varieties for offspring that reproduce true to their mother plant. Mixing some lime into the soil adds calcium that will help balance soil minerals, helping prevent some types of fruit deformities as well as blossom end rot.

Tomatoes are America's most popular garden crop, but they are not necessarily the easiest crop to grow. Even the most experienced gardeners occasionally find themselves at a loss as to why their tomato plants fail. Here are a few helpful guidelines for understanding tomatoes. The more you know about their needs and growth habits, the easier it will be to cope with their sometimes puzzling behavior.

Developing a Fertilizing Schedule

Tomato plants have a heavy workload, so their soil needs to provide them with a good supply of nutrients. To produce a crop of fruit successfully, they require moderate levels of nitrogen and phosphorus and moderate to high levels of potassium and calcium. Before planting seedlings, mix 1 cup of kelp meal and 1 cup of bone meal into the bottom of the planting hole. This will provide your plants with the necessary potassium and phosphorus. As long as you are starting with good soil, no additional feeding should be necessary until fruit is set.

Once fruit is set, feed plants monthly with an organic fertilizer that is low in nitrogen and high in phosphorus and medium to high in potassium. If your plants are starting out in poor soil, water your plants weekly with 1 cup of a fish emulsion solution (1 Tbsp. fish emulsion per gallon of water). Continue this from planting until the first blossoms form.

Uniform Watering is Key

In the early stages of growth, before fruit has set, it is a good idea to put the plant under slight stress by stretching out the length of time between watering. After fruit has set, however, it's important to maintain uniform soil moisture. Fluctuating wet and dry spells can bring on stunting of plants, blossom-end rot and a host of other problems.

  • Fruit crack: If soil moisture varies too much- if the soil gets too dry and then it rains, for example - the fruit can experience a growth spurt, which may cause the skin to split and crack. If droughts are common to your area, plant crack-resistant varieties.

Failure to Set Fruit

  • Prolonged moisture: Rain or prolonged humid conditions hamper fruit set. Gardeners growing tomatoes in cool, humid climates have found that fruit set can be increased by shaking the plant (or tapping the stakes of trained plants) to release pollen. Do this in the middle of the afternoon when the temperature is highest and the humidity is low.
  • Temperature: Tomato plants are quite fussy when it comes to air temperature (especially at night). They won't set fruit when temperatures fall below 55 degrees or rise above 100 degrees F. In many cases the plants will flower, but the blossoms simply drop off before they are fertilized. One way to avoid this problem is to start the season with early maturing varieties, which have been bred to set fruit at lower temperatures.

    Once the weather warms up, plant your main season varieties. Row covers can also provide a bit of protection from weather that is too cold. Use them in the spring until the weather warms up.

  • Too much nitrogen: Tomato plants sometimes fail to move from the growing stage to the fruiting stage of growth if they are given too much nitrogen early on in their development. Excess nitrogen and lots of water encourages young plants to keep on producing foliage at the expense of fruit. You can help the plant switch over to the fruiting stage by pinching out some of the terminal shoots, or by withholding water to check growth.

Sun Scald

When temperatures rise above 86 degrees F and the sun is at its most intense, fruit that is exposed to direct sunlight can fail to develop good, even red color. In climates where high summer temperatures are the norm, try to select varieties known for having a good dense foliage cover that will help protect developing fruit.

Leaf Curl

  • Hot weather: During midday summer heat or after a prolonged period of wet weather, a certain amount of leaf curl and wilt is normal- some varieties showing more sensitivity than others. For tomatoes growing in containers, wilted, droopy top-growth is their way of signaling the need for more water. Heavy pruning also seems to encourage leaf curl in some varieties.
  • Tobacco mosaic virus: This is a disease spread on seeds and by contact - not contact by insects, but by way of contaminated tools or even a gardeners own hands (smokers can spread it because it is often present in cigarette tobacco). Affected plants will have leaves that are curled and/or mottled, with discolored pale green or yellow fruits.

Misshapen Fruits, Dropped Leaves, & Other Evils

Tomato problems are usually caused by nutrient deficiencies, viruses, fungi, or insects. Some tomato varieties are more resistant to problems than others, and as always, good cultural practices can go a long way in reducing or eliminating many problems.

  • Blossom-end rot: Blossom-end rot appears as a large, leathery scar (rot) on the blossom end of the fruits. It can occur at any stage of development, and is usually caused by a lack of calcium. The calcium may be present in the soil, but it's not being transported to the fruits where it's needed, usually as a result of uneven watering. Blossom-end rot can also affect the inside of the fruit. When this happens, the outside of the tomato appears normal, while the inside is rotten and fuzzy.
  • Catfacing: The fruits are misshapen with bulges, crevices, scars or holes at the blossom ends. Catfacing is caused by anything that damages the fruit as it begins to develop within the flower. This includes heat, dry soil, excessive nitrogen, and especially, cold temperatures.
  • Fungal diseases: Early blight and tomato late blight are fungal diseases that are active during periods of warm, moist weather. The spores are usually spread by wind, splashing water, or contaminated tools. Early blight appears as irregularly shaped spots on lower leaves with a subtle bull's-eye pattern, and then gradually infects higher sets of leaves. Eventually, the infected leaves turn yellow and drop off, and the fruits develop dark, sunken blemishes.

    Late blight appears as dark green or brown patches on leaves and stems. Gray fuzz may appear on the undersides of leaves, while the stem ends of the fruit develop slimy brown patches.

  • Wilts: The other two major tomato diseases are fusarium or verticillium wilt. Plants may become affected early in the season, while the symptoms show up later - often just as the fruit starts to ripen. One day your tomato plants look fine, and the next day they are suddenly yellow and wilted.

The best ways to avoid tomato problems is to follow good cultural practices and start with disease-resistant plants. In catalogs and on plant tags, initials given after the variety name indicates kinds of resistance. Double initials indicate resistance to more than one strain of that type of disease.

V = verticillium wilt; F = fusarium wilt; T = tobacco mosaic virus; A = alternaria (early blight).

tomato suckers

CommentPin It! Was this helpful? 1

Tomato suckers are side shoots that grow out of the place where a branch meets the stem. If left to grow, they will compete with the main plant for nutrients. You may get more fruit, but they will be smaller. It's recommended to prune them. They are really easy to remove; all you need are your fingers!

If you like big ripe tomatoes, stick your tomato or tie it to a garden fence to keep it off the ground. Then when it gets growing good, take all the small branches off, leaving the 4 biggest branches. When more suckers start to grow, pinch them off of the plant.
