INTRODUCING TOMATO SEEDS

The tomato species come originally from Mexico, western South America, and Central America. Tomato seeds grow into a vegetable garden staple rich in vitamins A and C. They are healthy vegetables, whether eaten fresh as a snack or incorporated into cooked meals. These plants grow anywhere from 1 to 6 feet in height. Depending on the variety, they may require staking or caging to support potentially heavy fruits. Tomatoes grow well in USDA hardiness zones 5 to 13.

HOW TO PLANT TOMATO SEEDS

Sow tomato seeds indoors, around six to eight weeks before the final frost. Use small pots, filled with a sterile seed starting mix. Lightly cover the seeds with soil. Consistently keep the soil moist, in warm conditions. This will encourage germination, which happens in 5 to 10 days. Allow the seedlings the develop and pot them up, burying deeply to allow roots to fully develop before hardening them off. Make sure the danger of frost has passed before transplanting as tomatoes are intolerant to cold. Space seedlings about 2 feet apart for determinate varieties, and 3 feet apart for indeterminate varieties.

MAINTAINING TOMATO PLANTS

Tomato plants will require regular care to thrive. They need at least six to eight hours of direct sunlight daily, with frequent watering. Amending the soil with organic manure or compost before transplanting will help the growth of juicy fruits immensely. These plants are heavy feeders, so this practice can also be done several times during the season, to ensure continuous growth and fruiting. As the plants grow, support them with stakes or cages as needed. This will also help with prevention from pests and diseases. Removing suckers from indeterminate varieties is a good practice to manage the plant’s energy and improve air circulation.

Growing tomatoes will promote you to a stellar gardener. This is a wonderful plant, offering delicious, useful fruits and requiring special care and love. Given the many, many varieties available, you can grow an abundance of different sizes, colors, tastes, and shapes at home and enjoy the unmatched flavor of freshly harvested, homegrown tomatoes.

Frequently Asked Questions

What are heirloom seeds?

Heirloom seeds are the types of seeds your grandparents grew. These varieties have been passed down from generation to generation. They’re old reliable open-pollinated varieties that aren’t typically grown commercially. Instead, they have a rich history that predates modern breeding techniques. You can learn more about open-pollinated, heirloom, and non-GMO seeds in our Survival Garden Training blog.

How do I know my seeds are fresh?

Every seed packet includes a "packed for" date, and we germination test each seed lot before packaging to ensure you receive viable, high-quality seeds that are ready to grow.

Are your seeds chemically treated?

No, we do not pre-treat our seeds. All of our garden seeds are untreated, open-pollinated, non-GMO, and heirloom varieties. They are kept in temperature-controlled cooler storage until they are packed and shipped to keep them pest and disease-free.

Will your seeds grow in my USDA Hardiness zone?

The seeds in our collections are specifically chosen from varieties that can be successfully grown from Zone 3 to Zone 10 USDA Hardiness Zones. However, individual varieties have specific needs to thrive in different environments. Each seed pack has optimal temperatures for germination and instructions on seed starting. Consult local frost dates to plan your garden and get the most out of your seeds.

What is the shelf life of these garden seeds?

Most seeds remain viable for 3 to 5 years or longer when stored properly. Check your seed packet for specific varieties. For best results, keep your seeds in a cool, dry place away from direct sunlight and moisture. Store them in an airtight container in a consistent temperature environment—a refrigerator or cool basement works well. Proper storage helps maintain germination rates and extends seed life well beyond the packed date.

Where are Survival Garden Seeds sourced?

The majority of our seeds are sourced in the United States, with a few exceptions when the seed is difficult to source domestically. Whenever we do have to source outside of the US, we ensure our seeds are safe to grow, non-GMO, heirloom varieties that meet our standards for germination and reliability.
