Tomato 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 to different parts of your garden each year to avoid disease. The optimum temperatures for growing tomatoes from seeds are between 80°F and 85°F. Plant your seeds indoors 10 to 12 weeks before setting them outside. Use Miracle-Gro Seed Starting Material for the best germination results. We have tested other Seed Starting mixes and experienced poor germination rates. Do not add any soil, fertilizers, or other chemicals to the seed starting material. Do not use Jiffy peat pots, plugs, or potting soil, or covers, as the soil may become too dry or too wet, which can lead to disease, fungus, and poor germination. Do not bottom-water the seeds, as this causes the seed-starting material to become too wet and can lead to poor germination. We have experienced disease and low germination when using these types of products and covering the pots and trays. When seedlings are 4" tall, transplant them into 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 cloth strips. 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 only in the morning, on the side of the plants, 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 fully mature using garden scissors 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.
