Growing Tomatoes Made Easy: A Beginner’s Guide to Success
There’s nothing quite like the taste of a homegrown tomato. If you’ve been wanting to try growing your own, but you’re not sure where to start, you’ve found the right place and I’m so glad you’re here!
I’ve been growing tomatoes for years, and through trial and error, I’ve learned what works (and what definitely doesn’t). Let’s walk through the process together, step by step, so you can grow strong, healthy tomato plants. Ready? Here are the things I wish I knew when I first started growing tomatoes.
Choosing Your Tomato Plants
The first thing to decide is whether you want to grow tomatoes from seed or purchase young plants from a garden center.
- Starting from Seed – This gives you more variety choices and can be cost-effective, but it takes extra time and care.
- Buying Plants – A great option for beginners! You can skip the indoor seed-starting process and plant directly in your garden after the last frost.
There are two main types of tomato plants:
- Determinate (Bush) Tomatoes – These grow to a set height, produce all their fruit at once, and then they’re done. They’re great for canning and making sauces since you’ll get a big harvest at once.
- Indeterminate (Vining) Tomatoes – These keep growing and producing all season long, so they’re ideal if you want fresh tomatoes throughout the summer. They’ll need staking or caging for support.
Popular Tomato Varieties
- For Slicing: Beefsteak, Brandywine, Cherokee Purple, Big Boy
- For Sauces & Pastes: Roma, San Marzano, Amish Paste
- For Drying: Principe Borghese, Roma, San Marzano
Starting Seeds Indoors
If you decide to start from seed, begin about 6-8 weeks before your last frost date. Here’s how:
- Fill Seed Trays or Containers – Use a quality seed-starting mix. Regular garden soil is too heavy and can introduce disease.
- Plant the Seeds – Place seeds about ¼ inch deep in the soil and lightly cover them with plastic wrap.
- Keep Them Warm – Tomatoes need warmth to germinate. Keep the trays at around 70-75°F. A heat mat can help if your house is on the cooler side.
- Water Gently – Keep the soil moist but not soggy. I like to bottom water the trays to encourage roots to grow deep, just be careful not to let them sit in the water for more than 15 minutes.
- Provide Light – Once the seeds sprout remove the plastic wrap, they need at least 12-16 hours of light per day. If you don’t have a bright window, a grow light works wonders. This is the one I use!
Transplanting and Hardening Off
Once your seedlings are about 6 inches tall and have a few sets of true leaves, it’s time to get them ready for the garden.
- Hardening Off – About a week before planting, start placing your seedlings outside for a few hours each day, gradually increasing their time outdoors. This helps them adjust to sun and wind. Not in direct sunlight, because they could fry (ask me how I know. Ha!).
- Planting in the Garden – Choose a sunny spot (tomatoes love at least 6-8 hours of sunlight). Space them about 2-3 feet apart to give them room to grow.
Supporting and Pruning
- Cages and Stakes – Indeterminate tomatoes need strong support. Really strong. I like to use sturdy cages or stake them with tall wooden poles. Even cattle panel is a great idea.
- Pruning – For indeterminate varieties, remove the suckers (the little shoots that grow between the main stem and branches). This helps direct energy into fruit production instead of excess leaves.
Common Mistakes to Avoid
- Overwatering – Tomatoes hate wet feet. Water deeply but let the soil dry out between waterings.
- Planting Too Early – Cold soil stunts growth. Wait until nighttime temps stay above 50°F.
- Ignoring Blossom End Rot – This is caused by calcium deficiency and uneven watering. Mulching and consistent watering help prevent it. I’ve crushed egg shells and sprinkled this on the soil before watering and it worked wonders.
- Crowding Plants – Good airflow prevents disease. Give your tomatoes space!
Attracting Beneficial Insects
Ladybugs are fantastic natural predators for aphids and other pests that can damage your tomatoes. To attract more ladybugs to your garden, plant flowers and herbs that they love, such as:
- Dill
- Fennel
- Marigolds
- Yarrow
- Calendula
- Chamomile
- Sweet Alyssum
These plants not only help keep pests under control but also add beauty and biodiversity to your garden!
Harvesting and Enjoying!
Once your tomatoes are deep in color and slightly soft to the touch, they’re ready to pick! For the best flavor, let them ripen on the vine. Then, slice them up for a fresh sandwich or cook them down into a rich sauce. Congratulations! You’ve just grown a beautiful part of Summer.
FAQ
1. How often should I water my tomato plants? Tomatoes need deep, consistent watering. Water about 1-2 inches per week, but let the soil dry out slightly between waterings to prevent root rot.
2. Why are my tomato leaves turning yellow? Yellow leaves can be caused by overwatering, nutrient deficiencies, or lack of sunlight. Check your watering habits and consider adding compost or organic fertilizer.
3. Do I need to fertilize my tomato plants? Yes! Tomatoes are heavy feeders. Use a balanced fertilizer when transplanting, then switch to a fertilizer higher in phosphorus and potassium once they start flowering. Here are some natural options, you can use:
- Banana peels for potassium
- Crushed eggshells for calcium
- Compost or aged manure for balanced nutrients
- Wood ash for phosphorus
- Epsom salt (magnesium sulfate) for magnesium
4. How do I keep pests off my tomatoes? Common pests like aphids and hornworms can be controlled with by introducing beneficial insects like ladybugs. I’ve also used a blacklight in the evening to find the hornworms and remove them by hand (and feed to the chickens!). They glow in the blacklight!
5. What if my tomatoes aren’t ripening? If your tomatoes are staying green, try trimming back some of the leaves to let in more sunlight. You can also pick them and let them ripen indoors in a warm spot.
Growing tomatoes is one of the most rewarding things you can do in the garden. With a little care and patience, you’ll have a delicious harvest to enjoy all summer long.
