Tomato Seed Planting Information:

Tomato plants should be grown in warm areas and receive plenty of sunlight, so choose a sunny spot in your garden. Relocate your tomato plants in different parts of your garden yearly to avoid diseases. The optimum temperatures for growing tomatoes from seeds are between 80 - 85 F. Plant your seeds indoors 10 to 12 weeks before setting them outside. Use Miracle Gro Seed Starting Material for best germination results. We have tested other Seed Starting mixes and experienced poor germination rates. Do not add any soil, fertilizers, and other chemicals to the seed starting material. Do not use jiffy peat pots, plugs, or potting soil, or use covers, as the soil may become too dry or too wet, which can lead to disease and fungus and poor germination results. Do not bottom water the seeds as this causes the seed starting material to become too wet and you will experience poor germination too. We have experienced disease and low germination when using these types of products and covering the pots and trays with covers. When seedlings are 4" tall, transplant them in larger pots. Plants should be at least 10" tall before transplanting outdoors. Plants should be planted outdoors in shady areas for several days before transplanting outdoors. Shelter the transplants to prevent sunburn, wilting, and rain damage. Spring planting should occur when the soil is warm, at least 3 weeks after the last frost, and when temperatures remain above 70 degrees F. You can plant early if you use water towers. To prevent branches from breaking from the weight of tomatoes, use 5 to 6 ft tall cages. To tie plants to stakes, use soft strips of cloth. Check indeterminate plants regularly and pinch off suckers and side branches where leaves join the stems. Plants can grow from 1 to 6 ft tall.

Soil Requirements:

Requires fertile slightly acidic soil in a well-drained location in the garden. Apply mulch, grass clippings, or straw around the base of the plant. Work the soil thoroughly before planting. Add well-rotted manure and compost.

Water Requirements:

Keep soil consistently moist, but not waterlogged. Water well during dry and hot spells. Water in the morning only, on the side of the plants and not directly on the leaves.

Fertilizer Requirements:

Use Slow Release (6 Month) Fertilizer when transplanting outdoors. Apply Miracle Gro Liquid Fertilizer every two weeks.

Harvest Tips:

Harvest tomatoes when they are fully mature using a garden scissor so you don't damage the plant. Pick them as they mature to encourage new fruit to form. Remove any decayed tomatoes from the plant.

F – Fusarium Wilt (Race 1)

Scientific Name: Fusarium oxysporum

Type: Fungus

Fusarium Wilt, Race 1, is a fungal disease that affects the growth of tomatoes. It is one of the most devastating of all soil-borne diseases. Race 1 is the most widely found throughout the United States, especially in warm regions of the country. It attacks the roots of the plants and moves up the stems. Symptoms include yellowing and browning of the older bottom leaves, stunting, and wilting. Often the entire plant will die. Usually little or no fruit develops. The infected plants will produce inferior and unmarketable tomatoes. It can cause significant yield loss and even total crops losses. If you stick with Fusarium Wilt Resistant tomato varieties you don’t have to worry. Many of the older heirlooms don’t have any resistance to the disease, so if you grow these then you should keep an eye out for it. The infected plants should be removed and burned to avoid further infestation. Plan on using a 5 to 7 year crop rotation and avoid planting in the same location, year after year, as the disease can survive in the soil up to 10 years. The best option is to use disease resistant varieties.

TMV – Tobacco Mosaic Virus

Type: Virus - Potyvirus

Tobacco Mosaic Virus is a world-wide virus disease that affects the growth of eggplants, peppers, and tomatoes. Tobacco mosaic virus may cause significant losses in the field and in the greenhouse. The virus does not usually kill the plant, but it does cause damage to flowers, leaves, and the tomato. Symptoms include stunted or dwarfed plants, yellow-green mottling, blistering of the leaves, a light-green and dark-green mosaic pattern on the leaves, leaf distortion and curling of the leaves, fernleafing, and reduced growth rate and yields. Blooms may have brown streaks. Pepper plants may have yellow spotting on the leaves. Slightly sunken brown rings will appear on tomatoes. The virus is spread primarily by mechanical methods. The virus is not spread by aphids. Smokers can infect plants by handling them. Gardeners contaminate the plants when they touch tobacco products or infected plants or weeds and spread the virus to healthy plants. The virus can stay alive in dead plant material for long periods of time. It can survive on infected seeds, plant debris, and even clothing for months or years. Tobacco mosaic is one of the most highly persistent tomato diseases because it can remain viable for many years and is able to withstand high heat. The virus can survive for up to 50 years in dried plant debris. The infected plants should be removed and buried or burned to avoid further infestation. Plan on using a 3 year crop rotation and avoid planting in the same location, year after year. Keep your garden weed free. Wash your hands thoroughly and disinfect tools. Try to avoid smoking while working in the garden. Spraying plants with 20 percent nonfat dry milk has been shown to be somewhat effective in preventing the spread of the virus. The best option is to use disease resistant varieties.
