Tomatoes Solanum lycopersicum, Lycopersicon lycopersicum are the most popular homegrown vegetable. Like other plants in the potato family which includes eggplants, peppers, and tobacco , tomatoes are heat-loving plants that require a long, frost-free season and full sun.
The long, hot, sunny days of Minnesota summers are great for growing tomatoes. Start tomatoes from seeds indoors, five to six weeks before planting outside. In most of Minnesota, this is mid-April. Plants started earlier are difficult to manage and do not necessarily lead to better or earlier harvests.
For a stronger, more vigorous plant, plant tomatoes so that some of the stem is below the soil line and new roots will emerge from the buried part of the stem. Rather than digging a hole, dig a trench three to four inches deep. Remove the lowest leaves from each seedling, and lay the plant down in the trench, burying the stem up to just below the lowest remaining leaves.
Use good cultural control practices to reduce disease problems and allow for a successful harvest. Some tomato varieties are very vulnerable to diseases common in Minnesota. Others are naturally resistant. These letters are code for the diseases that these plants can resist.
If the variety name has no code letters, it may be vulnerable to all known tomato diseases. Even if you have not noticed disease symptoms previously, it is best not to plant tomatoes where other plants in the same family have grown recently. Disease spores in the soil can easily infect new plantings.
Bacterial canker of tomato may be spreading in Minnesota. This disease can transmit on seeds. If you start your own plants, be sure you start with clean seed.

Others cling to the plant and you should cut them off in clusters. You may choose to pick the fruit of varieties that drop before it is completely ripe. Most types will come off the plant easily when ripe or close to ripe. When frost threatens at the end of summer, pick all the fruit and bring it indoors.
Tomatoes picked truly green will probably never ripen to a good flavor, but those picked when the green color is decreasing and starting to turn white or pink should not disappoint. Fruit that is mature green, fully developed in size, but not color, will often ripen satisfactorily.
Some gardeners look for a star, or streak of white, on the bottom of the tomato. If the fruit is so truly unripe that the bottom is as green as the rest, it will not be worth ripening indoors. Store unripe fruits at room temperature, one layer deep, spaced apart without touching each other. Light is not necessary. Warm temperatures are more important than light in ripening the fruit. Fruit will ripen over the next few weeks. Check them often and eat them as they ripen.

Soil testing, fertilizer and mulch Have your soil tested to determine pH. Apply phosphorus P and potassium K according to soil test recommendations. Many Minnesota soils have enough phosphorus.
Unless your soil test report specifically recommends additional phosphorus, use a low- or no-phosphorus fertilizer. Too much nitrogen fertilization will lead to plants that are bushy, leafy, and slow to bear fruit. Do not use any fertilizer containing a weed killer "Weed and Feed" , as it may kill your vegetable plants. When the first fruits start to enlarge, apply fertilizer alongside the row of plants.
Spread the fertilizer in a six-inch wide band, and scratch it into the surface of the soil. Improve your soil by adding well-rotted manure or compost in spring or fall.
Do not use fresh manure as it may contain harmful bacteria and may increase weed problems. You may not need additional fertilizer applications, depending on how much organic matter you apply.

It is best to install plant supports —stakes, cages, spirals, or trellises— at the time of planting. If the plants were growing in a community pack or container, cut the soil between the plants with a knife so each plant can separate easily with a root ball attached. When transplanting seedlings in peat pots, make sure you do not expose the top edge of the peat pot above the soil surface. The peat pot will act like a wick and rapidly draw the moisture from the root ball, stressing the plant.
With a hand shovel, make a hole large enough for the root ball of the transplant. Firm the soil around the roots and water the transplants. How to keep your tomato plants healthy and productive. Watering Consistent soil moisture levels will help produce the best quality fruit. When soil moisture levels fluctuate during fruit growth, blossom-end rot can develop. Avoid overhead sprinkling.
Wet leaves are more disease prone, and soil splashed up onto the leaves can contain disease spores. Always soak the soil thoroughly when watering. Light watering can cause shallow root development, increase the crop's exposure to hot weather and drought stress, and reduce fruit quality. One inch of rainfall or irrigation per week is ideal. An inch of water will wet a sandy soil to a depth of ten inches, a heavy clay soil to six inches. Very sandy soils may require watering more often.
Use a trowel to see how far down the soil is wet. If it is only an inch or two, keep the water running. Controlling weeds Frequent, shallow cultivation with a garden hoe or trowel will kill weeds before they become a problem. Cultivate just deeply enough to cut the weeds off below the surface of the soil. Mulch with herbicide-free grass clippings, weed-free straw or other organic material to a depth of three to four inches to help prevent weed growth, decreasing the need for frequent cultivation.
