- Tomatoes are a warm-season annual that grow best when the soil temperature is at least 55°F and the air temperature ranges between 65° and 90°F. Tomatoes require from 50 to more than 90 warm, frost-free days to reach harvest.Tomatoes are commonly grown from seedlings started indoors and transplanted into the garden.row young seedlings on at 60° to 70°F; allow a gentle breeze to rustle over young seedlings each day so that they grow strong stems. About four weeks after germination, about two weeks after potting up seedlings the first time, pot them up again to 4-inch pots.

Rhododendrons and Azaleas Thin the plants once seedlings grow large enough to handle safely, spacing seedlings 18 to 36 inches apart and leaving 24 to 48 inches between rows. Provide extra protection for tomatoes plants by starting seeds indoors four to eight weeks before planting outdoors. February is a good time to sow seeds indoors.When planting indoors, use a light potting mix and plant seeds 1/2 inch deep. The seeds germinate well when kept evenly moist, warm and with six to eight hours of sunlight daily.he best time to sow seeds directly into the garden is after all danger of frost and soil has warmed, usually in May. Prepare the soil by amending with compost, peat moss or leaf mold, and deeply spade or plow the area. When sowing seeds, place three seeds in a 1/2-inch-deep hole with 1 inch between holes.

The Effect of Soil Temperature of Tomato Growth Warm soil stimulates tomato seeds to germinate faster than cooler earth. In fact, Organic Gardening reports that a 10-degree window between 75 and 85 degrees Fahrenheit is the best temperature range for successful germination in just one week.

Soil Temperatures for Seed Germination and Transplanting Vegetables If the soil temperature is not right, your seeds may fail to germinate. Both the seedlings that do sprout, and your garden transplants, can become stunted, or even die. For the absolutely best start to your garden season, plant your vegetables, both seeds and seedlings, when the soil temperatures are optimum to do so.ost seeds require warm soil temperatures down to 3 inches deep, to encourage germination. Use a garden soil thermometer, to check the soil temperature. Simply insert the thermometer to a depth of 2-3 inches.

- Step 3. Make sure the tomato plants are under greenhouse fluorescent lights for 18 to 22 hours each day. The best temperatures to grow tomatoes in a greenhouse are about 70 to 75 degrees F during the day, and 65 to 67 degrees F in the evening.Transplant the tomato plants from the containers you purchased the seedlings in once they have grown about twelve inches.omato plants are an ideal addition to any garden or landscape, especially since three to four plants can provide a generous harvest within three months of maturity. Tomatoes can be grown outdoors in or in a greenhouse, with the latter being the easiest option because you can control the environment and temperature.

Tomato Temperature Tolerance: Best Growing Temp For Tomatoes Most tomatoes are warm season plants and should only be planted after the danger of frost has passed. Tomato temperature tolerance for extreme heat or cold snaps is of extreme importance to the development of blossoms and subsequent fruit set.hese tomatoes set fruit not only in cooler temps, but also reach maturity in the shortest number of days; around 52-70 days. One of the most popular is called Early Girl, but there are many different cold hardy varieties to choose from. Some examples of hybrid tomatoes for cool climates are:

Starting Seedlings Indoors Fresh air: Put a fan in the room on low to keep the air circulating. This is surprisingly important. If the air is static the plants will not prosper. Temperature: Seeds need a warm environment to germinate. They will be comfortable with temperatures between 15-21°C (60-70F) during the day and will generally tolerate 10-15°C (50-60°F) overnight. Heating the soil will speed up germination, even though the surrounding air temperature may be chilly. Using seed heating pads or mats, even hot-water bottles and electric blankets under your seed trays, can make it possible to produce soil temperatures in the 80's.

What is the minimum temperature for tomato plants? Given the proper care, full-sized tomato transplants can be grown in 6 to 8 weeks. Before planting seeds, you must determine when your plants can be safely placed into the garden. Planting outdoors is best done about 1 or 2 weeks after the average last frost date for your area. Ask friends or use web resources to find your average last frost date, then do the math to calculate your seed starting date. #5 Plant Your Seeds Fill a small container with damp seed starting mix.

- If temperature is kept consistently and sufficiently warm, your tomato seeds will usually germinate within 5 to 10 days. Best to keep temperature range 70 to 80F (21 to 27C). The lower the temperature the slower the germination. However, temperatures below 50F (10C) or above 95F (35C) are poor for germination.

- Tomato Seed Starting Tips. Purchase and Prepare Your Tomato Seed. Because your garden soil compacts too easily and can harbor organisms that may cause diseases it's a better choice to purchase a prepared seed starting mix. A good commercial seed starting mix is often a blend of peat moss, vermiculite and perlite. I like to thoroughly combine the seed starting mix with warm water to make it useable since a dry mix is difficult to work with. You may want to let your seed starting mix sit wet overnight before using to assure that it is evenly soaked. The final product should be evenly dampened but not soggy wet. Select Your Tomato Seed Containers: As long as your tomato seeds get sufficient moisture, warmth and drainage almost any container will work. I used to use styrofoam cups with holes punched in the bottom. I've found that commercially available seed starting kits with peat or plastic containers are easy to use and proven successful. Most gardening stores will carry seed starting containers with single or multiple cells. I now use commercially available 128 cell seed trays.

The Effect of Soil Temperature of Tomato Growth But soil temperatures that exceed 95 degrees Fahrenheit by approximately 10 a.m. are too extreme for even the established tomato plant, states Colorado State University Extension. If the plant has flowered, the blossoms drop at this high temperature.ow Temperatures. Cool soil temperatures affect the tomato plant negatively, especially if they persist for more than a week. Temperatures dipping below 55 degrees Fahrenheit stops both pollen production and overall plant growth.
