Inside: Learn when to plant tomatoes in North Carolina – both when to start seeds indoors and when to transplant outdoors.

All winter long, I dream of that first ripe summer tomato. And every year, in my eagerness to taste fresh tomatoes, I almost always plant a tomato or two a little too early in my garden.

Some years this works out okay for me if we don’t have cold temperatures too late in the spring. But other years, I’ve lost tomato plants to a late frost because I just couldn’t wait any longer to get them in the ground.

But I want to save you from the heartache of waking up on a cold frosty morning and seeing your tomato plants black from the cold temperatures.

Knowing the best time to plant your tomato plants is vital to success. And various regions have different planting dates. If you are located in North Carolina, this post shares when to plant tomatoes in NC, whether you are starting them from seed indoors or transplanting them outside.

I’ll also share some of the best tomato varieties to grow in North Carolina.

How Do I Know When to Plant Tomatoes in NC?

To know when to plant your tomato plants in NC, you first need to know your last expected frost date in the spring. North Carolina has a wide range of gardening zones, from 6a to 8a with a few spots on the coast 8b and a few high peaks in the mountains 5b.

So using your last spring frost date will be the best way to determine when to plant your tomato plants. Don’t know your frost dates? This handy calculator will look it up for you based on your zip code.

You always want to wait until after your last expected frost to plant your tomato plants. Tomatoes are a warm-season crop and can’t handle any amount of frost.

They also don’t particularly enjoy cool soil temperatures, so it’s not a bad idea to wait a week or two after your last frost to give the soil a chance to warm up a bit.

When to Start Tomatoes Indoors

To get a head start on growing tomatoes, it is a good idea to start tomatoes from seed indoors unless you plan on buying transplants from a local garden center.

Tomato seeds should be started a minimum of 6 weeks before your last frost, but I like to start mine about 2 months before my frost date.

Once you have found your last expected frost date (I explained how earlier in this post.) count back 6 to 8 weeks to find the perfect time to start your seeds.

We have an average last frost date around April 14 and my Granddaddy always started his tomato plants on Valentine’s Day (February 14). Sow seed 1/4 inch deep in good quality potting soil or seed starting mix.

Keep the soil moist and the seeds should sprout within a week to 10 days. When starting tomatoes inside, you will definitely need to use grow lights to keep the tomato seedlings from getting leggy. See this post for more information on using grow lights.

The tomato seedlings need to be exposed to light for 12 to 14 hours each day to ensure optimal growth. Try to keep the lights 2 inches above the growing plants.

A week or two before it’s time to transplant your tomato plants to the garden, be sure to harden them off properly so they are prepared for the outdoors and you avoid transplant shock.

When to Plant Tomatoes Outdoors

You must wait until all danger of frost has passed before planting tomato transplants in the vegetable garden. In most of NC this is early spring, but the western North Carolina counties may need to wait until early May.

For the best results when transplanting young plants to the garden, wait until the soil temperature is above 50 degrees. (You can test your soil temperature with an inexpensive soil thermometer.)

If the soil is too cold it may stunt the plant’s growth. Tomatoes prefer a daytime temperature of 70-80 degrees and nighttime temperatures of 60-70 degrees. Unfortunately, this isn’t always easy to obtain.

And despite what a lot of people believe, tomatoes don’t like really high temperatures either. When the temperature rises above 85 or 90 degrees, the blossoms may start to fall off. And no tomato blossoms means no tomatoes.

However, if you keep the plants alive, they may start producing tomatoes again in late summer as the temperatures start to drop. Many people are still able to get a fall harvest of tomatoes if the insect pests and diseases don’t wipe the plants out first.

Tomatoes can be planted directly in the garden, in containers, or even in straw bales. When choosing a location for your tomatoes, keep in mind that tomato plants need full sun, which means 12 to 14 hours of sunlight a day.

Tomatoes also like fertile, well-drained soil with a pH of 6.2 to 6.8. If you don’t know your soil’s pH, you can learn how to do a soil test here.

​The Best Varieties of Tomatoes for North Carolina

In North Carolina, tomato varieties need to be able to handle our hot and humid conditions. While big heirloom varieties are popular right now, they can be difficult to grow in NC because of our hot summers.

While I love heirloom tomatoes just as much as anyone, beginning gardeners would do well to try a few hybrid varieties the first year or two. Many hybrid tomato cultivars are bred to be disease-resistant and the North Carolina humidity means fungal diseases are often a concern.

Because we often go long periods of time without rain, a crack-resistant variety of tomatoes can be a good option to consider also.

If you are just starting out growing a garden, I want you to have the best chance for success. And in the case of tomatoes, disease-resistant varieties are a great choice for the beginner.

A Quick Note About Determinate Versus Indeterminate Varieties

Tomato plants come in two types – determinate or indeterminate. Determinate tomatoes will produce a lot of fruit at one time over a period of a few weeks. This type is great for those who want to preserve a lot of tomatoes at one time.

Indeterminate tomatoes generally keep fruiting all season long. This also means the plants keep growing and growing. If you don’t know whether you have an indeterminate or determinate variety, you should be able to do a quick Google search to find out.

Indeterminate types will need to be staked, caged, or trellised to prevent them from sprawling all over the ground. However, I prefer to tie up all my tomatoes to prevent problems like soil-borne diseases and damage from bugs and critters.

Best Cherry Tomato Varieties

Cherry tomatoes are well-suited to North Carolina temperatures. And when it gets too hot for some of the larger varieties, cherry types will keep right on producing, usually to the end of the growing season (mid to late October.)

These are some of my favorite varieties to grow.

  • Super Sweet 100 – The best red cherry tomato I’ve found. Loads of sweet, sweet cherry tomatoes on long vines. It needs to be staked or caged really well. Very prolific.
  • Sun Gold Pole Cherry Tomato  – A beautiful yellow cherry tomato. These are even sweeter and tastier than the Super Sweet 100’s. This is my all-time favorite tomato variety for salads. Sun Gold tomatoes have become very popular in the last few years. I love using this kind mixed with red cherry or grape tomatoes to make a roasted cherry tomato sauce.
  • Jasper – Another red variety, this one seems to be a bit more crack-resistant than Super Sweet 100. We get dry spells and then a lot of rain at once which can cause the tomatoes to crack so I appreciate that this variety seems to hold up better to our fluctuating rainfall.

Best Varieties of Paste Tomatoes for NC

Paste types are best for preserving, whether canning, freezing, or dehydrating. They have less moisture and seeds than slicing tomatoes or cherry types.

Paste tomatoes are also often used for salsa and are the best variety for making homemade sun-dried tomatoes.

These are often called Roma tomatoes in the store because that is the name of a popular variety.

  • Roma VF – I grow this variety every year because it is consistent and reliable. The VF means it is resistant to Verticillium Wilt and Fusarium Wilt. These plants are fairly compact so this variety can be grown in containers too. It is a determinate variety so it will produce all the tomatoes over a 3-4 week span. Then it can be yanked from the garden in time to plant fall vegetables.
  • San Marzano – The standard for canning tomatoes. An indeterminate variety that will produce tomatoes all season long.
  • Supremo Bush Roma Tomato – This is a hybrid variety with extra large fruit and the plants produce lots of them. While they are listed as a determinate variety, I still had tomatoes on the vine in OCTOBER!

Best Varieties of Slicing Tomatoes

As I mentioned earlier, big, beefy slicing tomatoes can sometimes be difficult to grow in North Carolina because of our summer heat. However, I’ve had good success with the 3 varieties below. The tomatoes aren’t super large, but they do produce flavorful fruit in our climate.

  • Early Girl – I always like to grow one early variety and Early Girl is my favorite. These are small slicing tomatoes that grow in clusters. While not as flavorful as some of the later varieties, any homegrown tomato is better than a store-bought tomato!
  • Arkansas Traveler – This variety always seems to continue producing tomatoes from early summer to frost each year. This variety is bred for hot, humid climates and the plants in my garden are still usually producing tomatoes when I pull them out each fall.
  • Mountain Merit – This tomato has a fabulous disease resistance package and it resists cracking due to moisture fluctuations. This is a determinate variety but it does get fairly large so it will require staking.

Tomatoes Are Still the Most Popular Vegetable to Grow

Tomatoes are still the most popular vegetable for backyard gardeners to grow. With a long growing season, the North Carolina climate can produce some delicious tomatoes.

But the ideal time for planting tomatoes does depend on where in North Carolina you actually live. But planting tomatoes at the perfect time will help ensure you have a bountiful harvest of homegrown tomatoes.
